+---------------------------------------------------------------+

Changes to the ICD AdSCSI ST host adapter software since the
latest manual was printed:

-    3 levels of ICD software are now in distribution.  These are:
     PRO, LINK, and STHA (or regular) levels.  See notes on ICDBOOT 
     below.

-    This software supports the IDE drive in the Falcon 030 computer.
     The PRO version of ICDBOOT is suggested for use with the Falcon.
     The IDE drive is treated as SCSI ID 16.  ICD's driver emulates
     the required SCSI functions on the IDE drive.  Partitions on the
     IDE drive will be the first identified (i.e. C: D: E: etc.) followed
     by partitions found on SCSI drives.

-    The PRO and LINK levels of ICD software support Flopticalū drives.

-    CHANGE IN FLOPTICALū DRIVE SUPPORT: (Link and Pro level only)
     Previous versions of ICDFMT and ICDBOOT only allowed you to
     set up the 21 Mb diskettes according to the Insite Peripherals
     standard for information exchange between different computer
     systems.  These disks would not auto-boot and were not useable
     under TOS 1.0 - 1.2.  Because of popular demand, you are now
     given the choice in ICDFMT and INSTALL to set up the 21Mb
     diskettes either with the Standard (Insite Peripherals) or Atari
     format.  If you choose Atari format, the diskettes are useable
     with all TOS versions.  They can also be made to auto-boot if
     the the drive is the lowest ID in the system.   
 
-    A new hard disk installation program is included.  INSTALL.PRG is
     intended for the user who is totally unfamiliar with hard disks
     and wants an easy installation.  The program will automatically
     format the disk if necessary.  It will verify sectors, partition 
     the disk, sets up the auto-boot, and create a DESKTOP.INF file 
     and AUTO folder on partition C.  There are no user-selectable
     parameters.  Several warnings are given allowing the user to quit.
     After that, all data on the disk is destroyed.
     
     This program is also ideal for dealers to set up hard disks for
     their customers.  If more than one hard disk is connected, the user
     must choose which one to install.  After that, this disk is set
     up AS IF it is the only disk in the system.  In other words, the
     installed disk may then be taken to another system and plugged in.
     It will auto-boot and show a desktop with the correct icons for
     the number of partitions on the disk.

-    The TIMESET function is now incorporated in ICDBOOT.  This means
     that the hard drive clock will automatically be read and the
     system clock be set upon bootup, when using a host adapter with
     real-time clock.  This option may be disabled in the "Config" 
     option of HDUTIL for those choosing to use their Mega internal 
     clock or other clock device.  It is no longer necessary to have
     ICDTIME or TIMESET in your AUTO folder to set the system clock.
     You must still run ICDTIME to install the clock handler in memory
     before using the Control Panel or other software to reset the
     clock in the ICD host adapter.

-    ICDBOOT now recognizes hard disks formatted and partitioned
     with MS-DOS and FDISK on a PC.  This should simplify the transfer
     of files between PCs and STs using removable media (SyQuest, 
     etc.) much easier.  NOTE: (a) although reading and writing 
     MS-DOS partitions is supported, most of the ICD utilities 
     will not work with MS-DOS partitions. (b) very large DOS partitions
     have too many data clusters, which confuses TOS, so some DOS
     partitions will not be entered into the drive tables and will
     not be useable.

-    Previous versions of ICDBOOT would always change the screen 
     to medium resolution when booting with a color monitor.  
     The resolution is now configurable with HDUTIL, allowing 
     you to boot in any ST/TT graphics mode available on your 
     system.  As of ICDBOOT 5.5.0, you can also choose to completely
     skip any resolution change; this will be useful for those with
     1024x768 color monitors which require special driver software
     to load before any other program.

-    ICDBOOT will now work without an ICD host adapter connected
     to the system.  An ICD host adapter is still required for
     the use of the utilities such as HDUTIL, ICDFMT, etc., unless
     you own the PRO level of ICDBOOT.
     
     This feature was added so that people using an ICD tape
     backup system on an Atari TT or Mega STE can continue to
     boot their internal HD even with the tape drive disconnected.
     This feature, unfortunately, will NOT work on the STacy.
     
     When booting without an ICD host adapter present, unless using
     the PRO level of ICDBOOT, the ICD caches will be disabled, 
     resulting in performance similar to the hard disk drivers from 
     other companies.
     
-    This release now fully supports the Atari TT SCSI port as
     well as the ACSI port.  For the most part, hard drives 
     connected to the SCSI port of the TT can be treated just
     like drives connected to the ICD AdSCSI host adapter.  The
     primary difference is that the devices connected to the ICD
     AdSCSI are numbered 0-7 and the devices connected to the TT
     SCSI port are devices 8-15.  Since the TT itself is a SCSI
     device, it uses one of the device numbers.  The ICD software
     sets the TT to SCSI ID #7 (device 15), so that number is not
     available for any other devices.

     Drive letters are assigned to devices attached to the SCSI 
     port before those attached to the ACSI/DMA port.

     Keep in mind that an ICD AdSCSI host adapter is still 
     required to use the ICD host adapter software on the TT, unless
     you have the PRO level of ICDBOOT.

-    You do not always need to run HDUTIL to install a new ICDBOOT
     on your hard drive.  If the drive is already set up to auto-boot
     all you need to do is to copy ICDBOOT.PRG to the root or main
     directory of drive C:, rename your old ICDBOOT.SYS (to .SYX) or 
     trash it, then rename ICDBOOT.PRG to ICDBOOT.SYS and reboot.

-    COPYFIX.PRG has been updated to fix a bug which caused 
     compatibility problems with several applications.  There 
     should no longer be any problems with it.

-    All programs have been tested and modified as necessary to 
     present a proper display in the Atari TT's new graphics 
     modes.  Be advised, though, that any programs which didn't 
     work in the ST's low-resolution also will not work in TT 
     low-res (256 color mode).

-    Several minor bugs have been fixed.  Because of this, it is 
     advisable that you always use the latest version of the ICD 
     AdSCSI ST host adapter software.  Updates to all programs
     (except the PRO and LINK levels of ICDBOOT) are available on
     the ICD BBS, GEnie, or CompuServe.

-    When using the ESC key to disable the booter options, only
     the caching gets disabled.  The TOS buffers are still 
     allocated so that BGM partitions can be accessed.  If you
     need the additional memory, use HDUTIL to disable the
     buffers and reboot.

-    Simple statistics on the cache effectiveness are maintained 
     and can be checked with CACHEHIT.TOS.

-    It is now easier to bypass the hard disk auto-boot and force
     bootup from floppy disk drive A.  See HDUTIL below.

-    HDUTIL now has a new feature, called "Wipe".  See HDUTIL
     below.

-    STacy users, using ICD PRO software and ICDFMT, see special
     note below about determining drive size.

+---------------------------------------------------------------+
 
Changes to files on the distribution diskette: 
 
ADSCSI.CPX
     This is an extension for Atari's Extensible Control Panel
     (XCONTROL).  See the file ADSCSI.TXT for additional
     information.
     
BOOTFIX.TOS
     This has been updated to support drives attached to the TT
     SCSI port as well as the ACSI\DMA port.

     This version also disables Parity checking on Quantum ELS
     series 3 1/2" hard drives.  Of course, to do this, the drive
     must be connected to an AdSCSI or Advantage series host adapter.

CACHEHIT.TOS
     This program displays the effectiveness of the caches.  It 
     displays the percentage of reads which were satisfied by 
     the cache, and the percentage of writes which updated 
     entries already in the cache.  This can be used to 
     determine what cache settings are the most efficient for 
     your system.

     It's important to note that this only gives statistics for 
     the cache buffers, and not the TOS buffers.  The TOS 
     buffers are maintained by the operating system and can't be 
     checked.  The ICD AdSCSI ST host adapter manual explains 
     the TOS buffers in more detail.

CACHEOFF.PRG
CACHEON.PRG
     These programs are used to enable and disable the write
     cache function of ICDBOOT.  Users of the Supercharger PC
     emulator must turn off the write cache before running the
     Supercharger intialization program or the Supercharger will 
     NOT be able to write to the hard disk.

     Turning the cache off this way does not reduce memory usage.

CFGCBOOT.PRG
     This program configures COLDBOOT.PRG to skip selected 
     ACSI/DMA devices.  See section on COLDBOOT.PRG (below) for 
     additional documentation.

CLEANUP.PRG
     Detects and corrects structural and logical errors on GEM/BGM
     partitions.

     This is included only on the PRO level version, and is also
     available for separate purchase.

COLDBOOT.PRG
     This has been updated to support devices attached to the TT
     SCSI port as well as the ACSI/DMA port.

     Versions 1.30 and later of ICD COLDBOOT.PRG are 
     configurable to allow skipping of the ACSI/DMA ID of the
     Supercharger from Talon Technologies.  To configure COLDBOOT
     run CFGCBOOT and specify the ID(s) you wish to skip when
     doing a coldboot.  The Supercharger is normally shipped as
     ID 3.  This should only be necessary for those users who do 
     not have Quantum, Seagate, or other drives which autoboot
     upon power-up, and who are also using the Supercharger.

COPYFIX.PRG
     This has been updated to fix a bug which caused 
     compatibility problems with several applications.  There 
     should no longer be any problems with it.

DESKTOP.PRG
     This program (formerly a desk accessory) has been updated 
     to be compatible the Atari TT and all TOS versions.  See 
     DESKTOP.DOC for a more complete explanation of changes since
     previous versions.  DO NOT RENAME DESKTOP.PRG TO DESKTOP.ACC;
     attempting to do this and installing the file as an accessory
     will give you grief.  This program is NOT designed to be 
     renamed to .ACC.

EJECT.TOS
     A program to eject diskettes from the Macintosh versions of 
     Flopticalū drives.  This may be renamed as EJECT.TTP to run
     from a command line, or you can create a file EJECT.LST for
     it to run from.  For more information, run the program with
     no parameters, see example file EJECT.LSX, or read HDPARK.DOC.
     This program is included only with the Link and Pro levels of
     ICD software.

HDPARK.TOS 
     This has been updated to support the TT SCSI port.
     This program replaces MAKEPARK.PRG.  See HDPARK.DOC for 
     complete documentation.

HDPARTS.TOS
     This program displays various statistics about each hard 
     drive partition on the system.  For the most part, this 
     information will only be of use to people who have some 
     understanding of disk structures.

HDUTIL.PRG
     There is now an option to set the bootup screen resolution 
     in ICDBOOT (it previously defaulted to medium resolution on 
     a color monitor).

     This has been updated to support the TT SCSI port.  This
     affects several functions:

     -    Setting a hard disk for auto-booting will result in 
          either TT-SCSI boot sectors or ACSI/DMA boot sectors
          being written to the drive based on which port the
          drive is connected to.  If you ever move the drive to 
          the other port, you will have to reinstall the boot 
          sector with HDUTIL.

     -    If run on a Falcon 030, the auto-boot code will be
          written on the internal IDE drive.

     -    It is possible to disable scanning of any of the 16
          devices.  The device number of the TT itself will 
          never be scanned, regardless of the button settings.

     It is now easier to bypass the hard disk auto-boot and force
     bootup from floppy disk drive A.  Just hold down ALTERNATE
     only.  It is no longer necessary to hold down SHIFT-CONTROL-
     ALTERNATE.  You must use HDUTIL to reinstall the "Boot" to
     take advantage of this.

     HDUTIL now has a new feature, called "Wipe".  Previously the
     only partition-blanking feature was "Zero", which blanked
     the directories and File Allocation Tables.  The data was
     still present and a talented snoop could possibly recover
     it.  "Wipe" will zero out every sector of the partition, so
     that you do not have to be concerned about any of your 
     confidential data falling into the wrong hands.

HOST.TOS
     This is a utility to tell you what kind of host adapter you 
     have connected to each hard drive on line.   Note that it is
     not always possible to differentiate between Link, AdSCSI Plus ST,
     AdSCSI ST, and AdSCSI Micro ST host adapters.  This is
     particularly true when multiple host adapters are connected.

     It is also not possible to differentiate between one of 
     ICD's original STHA boards and one of those made by another
     manufacturer.  These items do NOT have signatures.  We are 
     merely seeing which ones do full SCSI commands and which
     ones have ICD real time clocks.

ICDBOOT.PRG
     The names of SCSI hard disk devices are now displayed as they
     are found, followed by the partitions logged from these devices
     (if any).

     If you wish to pause ICDBOOT to read the information it prints,
     press <control-S>; press <control-Q> to restart the program.

     There are 3 levels of ICDBOOT now in distribution.  
     (1) The PRO level, which installs on all ST and TT computers 
         regardless of whether an ICD host adapter is found.  The
         PRO level supports Flopticalū drives.  This level is 
         available only for purchase.  To obtain updates, original
         disk must be returned to ICD with a $10 fee.

     (2) The LINK level, which supports Flopticalū drives.  This
         level is shipped only with the Link host adapter.  To
         obtain updates, original disk must be returned to ICD with
         a $10 fee.

     (3) The regular level.  Flopticalū drives are not supported.  
         Updates are available from ICD on disk for $10 (original disk
         not required), or on the ICD BBS, GEnie, or CompuServe.

     Now supports most MS-DOS formatted/partitioned hard disks.
     Some MS-DOS partitions have too many data clusters and give
     TOS problems.  These partitions are not supported.

     Can now be used without an ICD host adapter present.  An 
     ICD host adapter is still required to install the booter 
     and to use the various other utilities.  The caching will 
     be disabled when running without an ICD host adapter, except
     for the PRO level of ICDBOOT.

     This has been updated to support devices connected to the 
     TT SCSI port as well as devices connected to the standard
     ACSI/DMA port.  Full SCSI arbitration is supported on the 
     SCSI port, which offers great potential.

     A few other minor bugs were fixed, so it is advisable to 
     use this version even if you don't own a TT.

ICDFMT.PRG
     This program can now format drives connected to the TT SCSI
     port as well as the ACSI/DMA port.  As with the other 
     software, the devices attached to the SCSI port are 
     numbered 8-15.  

     Calculation of DEFAULT and SPLIT partitions now make one 5.00
     meg drive followed by equally-sized partitions.  This is to
     encourage you to use a small drive C.  In case your first drive
     gets destroyed (which seems to happen randomly on Atari computers,
     although it is VERY rare), you do not lose a lot of data.  This
     feature may be disabled by holding down the Alternate key while
     clicking on DEFAULT or SPLIT, or while clicking on OK in the
     dialog headed "Split into several partitions...".   However, you
     are VERY STRONGLY encouraged to use a small drive C.

     STacy users with Conner drives:  because of a severe bug in Conner
     drive firmware, it is necessary to avoid the standard methods of
     determining drive size.  You must use any ordinary ASCII text
     editor to create a file called INTERNAL.HD in the same folder as
     ICDFMT.  The first line of this file must match EXACTLY what the
     Conner drive returns when you run IDCHECK.  Spaces are important.
     The second line is the number of the LAST SECTOR on the Conner
     drive.  Here is an example of INTERNAL.HD:

     CONNER  CP3020
     41117

     If your drive is not a CP3020, you will have to determine the
     last sector through trial and error.  Start with a value large
     enough for your drive (i.e. 45000 for a 20 meg, 90000 for a 40
     meg).  Run ICDFMT and select Partition, then Partition Entire Hard
     Disk.  The program will verify the sectors and will stop when the
     Conner bug kicks in.  If the sector the program is at is a multiple
     of 32, add 31 to that value, use that value as the second line of
     INTERNAL.HD, and repeat the test.  Note that the drive will have to
     be turned off and back on again to rerun ICDFMT.  This time subtract 
     1 from the sector showing and that should be the correct value.

ICDFMT.DAT
     This file is updated from time to time to include more hard drive 
     models.  (See additional documentation below).  This file is used
     for and necessary for ST506/412 type drives only.  It is not used
     for SCSI drives; information about these drives is needed by
     asking the drive for it.  If ICDFMT.DAT is needed and not found,
     you will be able to fill in the heads and cylinders and proceed.

ICDTIME.PRG

IDCHECK.PRG
     This has been updated to check devices connected to the TT
     SCSI port as well as the ACSI/DMA port.  When running on a 
     TT, the left-hand column shows the devices attached to the 
     SCSI port (including the TT itself) and the right-hand 
     column shows the devices attached to the ACSI port.  Also shows
     IDE drive on the Falcon 030.

INSTALL.PRG
     Automated setup of a hard disk.  Formats (if necessary), verifies,
     partitions, sets up auto-boot, and creates a desktop.  Ideal for
     the novice user who wants a quick setup, and for dealers setting
     up hard disks for customers.  When done, the disk should boot up
     when connected to any ST or TT with any TOS version and display a
     desktop containing all the icons necessary for the number of 
     partitions.

RATEHD.PRG 
     This has been updated to test drives connected to the TT 
     SCSI port as well as the ACSI/DMA port.  See RATEHD.DOC for 
     complete documentation.

SCSI.PRG
     This is a SCSI Command tester which can also be used as a sector
     editor.  This is included only on the PRO level of ICD software.

TIMESET.PRG

WHEREIS.TOS
 
+---------------------------------------------------------------+

The ICDFMT.DAT File 
------------------- 
 
The ICDFMT.DAT file contains information about ST506/412 
compatible hard drives only (not drives with embedded SCSI 
controllers).  The ICDFMT.PRG gets data about SCSI embedded
drives by doing an Inquiry and Mode Sense to get the necessary
data directly from the drive.

To add a drive, enter the following information about your drive 
in the EXACT same format (position sensitive) as the others 
listed as follows:  a. The letter 'd' to indicate a drive b. The
name of the drive c. The number of heads on the drive d. The
number of cylinders on the drive e. The cylinder number at which
to start using reduced write current (if not sure, then just put
same number as # of cylinders) f. The cylinder number at which to
start using write precomp (if not sure, then just put same number
as # of cylinders) g. The parking cylinder (usually 40-50
cylinders beyond the last cylinder).  h. The step rate; normally 
2 (unless very old).  0 = 3ms non-buffered step for older drives
(ST506) 1 = 28us buffered step rate (ST412 and maybe others) 2 =
15us buffered step rate (Almost all new drives)

Presently we support 98% of all hard drives and SCSI controllers
that can be used on the Atari ST.  Some may not work on the ST at
all.  If in doubt, try it, or you can call or write our technical
support department.

Miscellaneous Notes
------------------- 

Connecting Supra/Atari Drives:
     Supra drives are initially set to SCSI=0, LUN=0, so if you 
     want to boot off your ICD drive, you may wish to change the
     ID of the Supra drive.  Alternatively, you could set the
     SCSI ID of the controller or drive in your ICD drive to a
     different value and boot off the Supra drive.  Contact ICD
     Technical Support for assistance if necessary.
 
     Atari SH204 drives are also set to SCSI=0, LUN=0, BUT they 
     have a bug in their hardware.  They respond to ALL LUN
     numbers causing havoc to the system.  A provision in the
     drive handler has been made to only see LUN=0 with a SCSI ID
     of 7.  Therefore you will need to set the 3 position dip
     switch in your SH204 to ID 7 (flip all three switches to the
     other position).

     Atari Megafile (SH205) drives are set as SCSI=0, LUN=0.  The
     SCSI ID # is changeable inside the box.  It uses a 
     combination host adapter/controller board but can be
     formatted with our software as an Adaptec 4000 for their 20
     Meg and Adaptec 4070 for the 30 and 60 Meg drives.

Clock Battery:
     If the clock is way off or seems to return crazy times, the
     battery may be low. For a replacement battery, send $5.00, 
     unless your host adapter is in warranty.  If it is in
     warranty, call us and we will send a batter at no charge.  A
     new battery socket is available for an additional $3.00.
     Soldering is usually required with older original ICD ST
     Host Adapters.  The newer units already have the socket
     installed and replacing the battery is a very simple
     operation.  We will install battery and/or socket for $20 
     when unit is out of warranty.  

     If your clock seems to run fast or slow it is probably 
     adjustable.  Look for a variable capacitor labled VC1 near
     the clock battery.  Use a subminiature flat-bladed screwdriver.
     Insert the blade into the opening and turn clockwise to speed
     the clock up, counter-clockwise to slow it down.  Start with
     1/2 turn, let it go for a day and recheck and go from there.
     It is possible with a little patience to calibrate these
     clocks very accurately.  If your host adapter does not have
     VC1 about the only recourse is to try changing the clock chip.

Host Adapter Mounting:
     There are four mounting holes on the board; mount it as you
     see fit.  ICD makes a mounting bracket kit for the host 
     adapter which you can probably use in your application.  It
     is called the ST/MK and is US $8.95 plus S & H (contact us to 
     order, or for more information).

Using Multiple SCSI ID's and Host Adapters:
     When using multiple SCSI ID's and host adapters a few rules
     apply:

     -    Power up the device closest to the computer first
          (plugged in). Then power up the next out in the chain 
          and continue in this fashion until all devices are
          powered.  Now BOOT the computer.
 
     -    SCSI ID #0 will be the first device seen and will 
          provide the booter and AUTO folder for the system.  It
          will be assigned as C, D, E, etc.  The next SCSI ID
          found will provide the next partitions beginning after
          ID #0's and so on.  It does not matter physically where
          these drives are in the daisy chain except for power up
          procedures.  The SCSI ID #s also do not need to be
          consecutive although that is recommended for proper 
          software support by other companies.
 
Setting Up Your AUTO Folder For Programs Which Use GDOS:
     It is usually necessary to have GDOS be the last file in the
     AUTO folder.  Since the ST displays files in sorted order, 
     the only way to insure this is to create a JUNK folder, copy
     all files except GDOS to it, delete the AUTO folder, and
     recreate it.  Then copy all files back to the AUTO folder
     from JUNK, delete JUNK, and finally copy GDOS to the AUTO
     folder.

Setting Up Your Hard Drive To Boot pc-ditto From A Partition:
     First, set up the partition to boot with the HDUTIL 
     program. Create a JUNK folder on another drive and copy
     ICDBOOT.SYS to it. Now run the pc-ditto program's formatter
     which sets MS-DOS to boot.  Finally copy ICDBOOT.SYS back to
     the root directory of your boot drive.  Now when you boot,
     the ICD Boot Program will run...then pc-ditto will boot.
 
     CAUTION: If you disable autobooting with HDUTIL, you will
     probably destroy your pc-ditto boot information as well.

What To Do When You Get "Locked Out" Of Your Hard Disk:
     Installation of certain .ACC files may cause you to bomb
     every time you boot and you can't access your hard drive to
     remove or rename the offending file!

     To cure this: turn off the hard drive, place a copy of the ICD 
     ST host adapter disk in Drive A, and boot.  Double click on 
     IDCHECK.PRG and let it scan through drives.  At the end it will 
     be blank.  Now, turn on your hard drive.  Let it come up to 
     speed.  Click on Rescan and repeat until your drive is shown.  
     Then Exit.  Now locate ICDBOOT.PRG and double click on it.  
     Install an icon for Drive C: (click on one icon to make it dark, 
     then go to the menu bar under options for Install Disk Drive; 
     use a capital C!) and double-click on it.  Now you can rename 
     the offending .ACC file to some other extension, and then you 
     should be able once again to boot from your hard drive.

     If this doesn't work, call ICD, and we will help you regain
     access to the hard drive.

Suddenly your hard drive won't auto-boot:
     Something has trashed partition information or corrupted the
     ICDBOOT.SYS file.  First try re-running HDUTIL and 
     resetting the boot drive.  If this doesn't help, or if the
     Boot dialog shows no hard drives, something has wiped out
     your partition sector.  Try running Cleanup ST to try and
     save the partition.  Alternatively, you you can rewrite
     partition info using the ICDFMT.PRG.  To do this, run 
     ICDFMT and select PARTITION.  Re-enter your partition 
     information (of course you have kept a record of this).  
     Make sure all partitions are enabled (check mark under
     "On").  Select REWRITE PARTITION INFO ONLY at the bottom
     left side of the dialog box.  Be careful here!  This is one
     place you want to be ABSOLUTELY SURE that your information 
     is 100% correct.
