                        HyperDisk and Windows 3.0


   Windows Enhanced mode provides time sliced multitasking. If you use write
caching, watchout for <Ctrl><Alt><Del> (Soft Reboot) it will restart your
machine immediately without informing HyperDisk of the impending reboot.
Always exit Windows or wait until the disk updates are complete before you
reboot your system!

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 Windows 3.0 editor SYSEDIT) and add the following line in the
386 Enhanced section:

VirtualHDIrq=false

See the SYSINI3.TXT information file in your Windows 3.0 directory. Also,
to edit the SYSTEM.INI file you can use the Windows Application SYSEDIT.

To automaticlly release XMS memory for Windows 3.0, use the following
command parameter before running Windows 3.0

  HYPERDK cw:2048  ; set HyperDisk cache to 2048K bytes when running Win 3.0
                   ; you can set CW:nnn at anytime, or during installation
                   ; see the READTHIS file for example syntax

  WIN /3           ; run enhanced mode for 386 machine
                   ; alternately you may use standard or real modes

Please note: If most of the XMS memory is allocated to HyperDisk you must use
             the /3 option to force Windows 3.0 to issue it's startup call-out
             notice, otherwise Windows will start in real mode.


When Windows 3.0 starts HyperDisk will reduce it cache buffer to 2048K bytes.
If the current cache size is already smaller than 2048, it will remain
unchanged. 2048K is a example number you may choose 0 for no cache, or
starting with 32K upto the initial installed value. CW without a number 
disables the resize operations. See READTHIS for more examples.


Loading HyperDisk high in Chips and Tech. based machines:

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