I followed the latest SmartDrv vs HyperDisk debate with much interest.
Certain articles in favor of HyperDisk led me to give it a try and find out
for myself.  So I got a copy from Simtel and unzipped it.

Installing it was an easy task.  I set it up to use HYPER386.EXE, which
seemed to fit best with my system configuration (386/33 Compatible w/4Mb).
I then rebooted and except from the nagging screen, everything looked A-OK.

Holding my breath, I booted Windows...  And found myself in Real mode.
Ok so I realized HYPER386 had to be using all my extended memory and hadn't
released it, so I went back to DOS, found info on HYPER386's parameters and
reset it so as to use 1Mb, (N:1024).  Reboot PC, Reboot Windows.  This time,
I made it through in 386 enhanced.  However, I had read in the News that
Hyperdisk was supposed to release memory when entering Windows (ala Smartdrv).
So I looked in HyperDsk directory and found win3note.txt.  This text file
basically said to use Hyper286/386 with Himem, and HyperDKX with QEMM.
So I switched to HyperDKX (since I use QEMM), and used the N:1024:512 parameter
which was suppose to force HDK to release 512kb upon entering windows.

This time, windows woudn't boot.  I got a PAGING ERROR after seeing the
microsoft logo, and went back to DOS.

So now, I'm using Hyper386 with no memory release option.  As far I can see,
it's working fine, and it does make a visible difference from SmartDrv.
I'll give a try for a few weeks to see if it's reliable.  I will then decide
wether it's worth registering.

Has anyone had any success configuring HDK with QEMM512 and memory release
options?  What are the best settings on a 4Mb system?


Thanks in advance.
