****************************************************************************

The ASW-1420 1.21 BETA currently supports the following host adapters:

	Adaptec AHA-1540/1542 (ISA)
	Adaptec AHA-1640 (Microchannel)

The ASW-1220 1.21 BETA currently supports:

	Adaptec AHA-1520/1522 (ISA)
	Adaptec AHA-1510 (ISA)
	Adaptec AIC-6260 (SCSI on System board)

These drivers have not been tested with any version of OS/2 1.21 other 
than that shipped by Microsoft to OEMs.  Released versions of OS/2 1.21
from OEMs like Compaq, etc. are not necessarily supported at this time.

INSTALLATION:
------------

The ASW-1420 disk is organized as follows:

(root) \
	+-- readme.txt file
	|   
	+-- aha154x +-- install	
	|	    |
	|	    +-- disk1
	|      
	+-- aha1640 +-- install	
	|	    |
	|	    +-- disk1
	|      
	+-- aha152x +-- install	
	|	    |
	|	    +-- disk1
	|      
	+-- aha1510 +-- install
	|	    |
	|	    +-- disk1
	|      
	+-- cdrom


To install OS/2 1.21 with LADDR you must do the following:
	
	- Make a copy of the both the OS/2 install disk and OS/2
	  disk #1 for use with LADDR using the DISKCOPY command.
	  Do not install LADDR files onto your original OS/2 diskettes.

	- Copy all files in the appropriate "install" directory 
	  to the LADDR install disk.  There are separate "install" 
	  directories for each host adapter to facilitate installation.
		
	       	 \aha154x\install for the Adaptec AHA-1540/1542
		 \aha1640\install for the Adaptec AHA-1640
		 \aha152x\install for the Adapter AHA-1520/1522
		 \aha1510\install for the Adaptec AHA-1510/AIC-6260
	
	  In some cases there may not be sufficient space 
	  on the installation diskette for all the needed files.
	  See the section below on how to make more room on the
	  installation diskette.
 
	- Copy all files in the appropriate "disk1" directory 
	  to the LADDR disk #1.

	       	 \aha154x\disk1 for the Adaptec AHA-1540/1542
		 \aha1640\disk1 for the Adaptec AHA-1640
		 \aha152x\disk1 for the Adaptec AHA-1520/1522
		 \aha1510\disk1 for the Adaptec	AHA-1510/AIC-6260

	- Proceed with normal installation OS/2 installation using 
	  the LADDR version of the OS/2 install disk and disk #1.

If you already have an OS/2 1.21 system setup and would like 
to add LADDR you can take a shortcut and just copy the files in the
"install" and "disk1" directories for the appropriate host adapter
to the root directory of your hard disk.


Notes on AHA-1510/AIC-6260
--------------------------

The AHA-1510 and AIC-6260 are basically compatible with the AHA-152x except
that they do not include jumpers for configuring SCSI Id, Parity enable,
etc. For this reason, a separate directory has been setup for the 
AHA-1510/AIC-6260.  This directory contains the AHA-152x drivers but 
includes a different IOCONFIG.SYS to take the place of jumpers.
This IOCONFIG.SYS supports the following configurations:

	AHA-1510/AIC-6260 @ Port 340h, IRQ 11h, SCSI Id 7, 
		Parity Enabled,Synchronous Negotitiation Enabled
	
	AHA-1510/AIC-6260 @ Port 140h, IRQ 12h, SCSI Id 7
		Parity Enabled,Synchronous Negotitiation Enabled

If an AHA-152x is set for either of these configurations it will 
also function with the drivers in the AHA-1510 directory.

VIEW.EXE
--------
The VIEW.EXE utility is provided with this product to allow 
users to get information about currently loaded drivers.

CD-ROM INSTALLATION:
-------------------
To install the CD-ROM drivers you must do the following once OS/2 has
been installed with LADDR on the hard disk:

	- Copy the drivers in the CD-ROM directory to any directory
	  on the hard disk EXCEPT the root directory. 

		Example: \CDROM

	- Append the PATH to the CD-ROM drivers to the LIBPATH in the
	  config.sys.

		Example: LIBPATH=C:\OS2;C:\;C:\CDROM;

	- Add the following lines at the end of the config.sys:
	  This example uses driver path \CDROM:
		
		DEVICE=C:\CDROM\STDCDROM.VSD
		DEVICE=C:\CDROM\CDROM.TSD
		IFS=C:\CDROM\CDFS.IFS

Making more room available on the installation diskette:
-------------------------------------------------------

If the LADDR install files for one or more host adapter(s) will
not fit on the install diskette then space can be freed up 
by reducing the size of any unneeded video driver files.

Determine which files in the following list are needed for the target 
system.  The rest can be reduced in size by entering the following 
at the command line:

[a:\]copy con: xxx.RC@
<SPACE> <RETURN>
<CTRL-Z> <RETURN>

where xxx.RC@ is one of the following:

		CGA.RC@
		EGA.RC@
		VGA.RC@
		VGAM.RC@
		PLASMA.RC@
		8514.RC@
		8514M.RC@
		

Each driver file which is reduced in this way will free up approximately
4K of space on the install diskette.

OEMs using this product to build an OS/2 release should check the LADDR
development kit for info on restructuring the OS/2 install disk to
provide more room for LADDR drivers.
