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 5.11

To enable the automatic release of XMS/EMS memory from the cache for Windows
3.0, you must load Windows with the /S or /3 switches.  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 in Chips and Tech. based machines and Windows 3.0:

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
staged 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!
