HyperDisk and Windows 3.0

   HyperDisk gives you a true high-performance cache with the Win3
compatibility of SmartDrive.

Install HIMEM.SYS (or QEMM 5.10) before HyperDisk.
Install HyperDisk before Windows.

HYPER386 or HYPER286 may be used for Windows 3.0 and HIMEM.SYS.

HYPERDKX should be used with QEMM 5.10

To enable Advanced Update mode while in the WIN 3.0 environment, edit
SYSTEM.INI (use the Windows 3.0 editor SYSEDIT or NotePad) and add the
following lines in the 386 Enhanced section:

VirtualHDIrq=false

Note: This switch is optional, some systems may have reduced performance.

See the SYSINT2.txt and SYSINI3.TXT information files in your Windows 3.0
directory.  (To edit the SYSTEM.INI file you can use the Windows Application
SYSEDIT, found in your WIN\SYSTEM subdirectory, the Win3 Accessory NotePad,
or your favorite text editor.)

To enable the automatic release of XMS memory from the cache for Windows 3.0,
you must load Windows with the /3 switch.  Having 386ENH as your default Win3
mode will not by itself enable the cache reduction. HYPER??? syntax is
C:NNNN:nnnn, where NNNN is cache size outside of Win3 and nnnn is cache size
to use with Win3. You may also use CW:nnnn either as an initial load switch
for HyperDisk or with HYPERDK from the DOS command line to set the size of
cache to use while in Windows.  See the READTHIS file for examples.


Loading HyperDisk high with Windows 3 in Chips and Tech. based machines:

Be sure to add the appropriate EMMEXCLUDE= statement to the [386Enh] section of
SYSTEM.INI.  EMMEXCLUDE=E800-EFFFF or EMMEXCLUDE=E400-EFFF will be correct
depending on how much memory is used by HyperDisk.


CAUTION:  Windows Enhanced mode provides time-sliced multitasking. If you use
write caching, be careful with <Ctrl><Alt><Del> (Soft Reboot) when under Win3;
it will restart your machine immediately without informing HyperDisk of the
impending reboot, and could thus cause loss of data not yet written from the
cache to the disk.  Always exit Windows or wait until the disk updates are
complete before you reboot your system!
