I installed PC Tools version 9.0 by Central Point on to my DOS 6.22 compact flash drive, and selected to install their RAM Boost utility. After this utility was installed, I ran this command line prompt:

mem /c /p

The information displayed told me that the largest executable size is 618K. I guess that's quite good? Currently, I have MSCDEX CD-ROM driver installed, and also cutemouse. I've heard of other products, such as QEMM, and I think running Microsoft's memmaker.exe also optimises DOS memory. Would anyone recommend that I either keep or remove the "RAM Boost" utility on my system?

I never used that tool, I had purchased QEMM (Quarterdeck Extended Memory Manager) way back and kept upgrading it as it worked like a champ on my old DOS systems.

I also dabled with MemMaker too which worked pretty well.

Does Ram Boost scan you configs and then reboot and test like the others do ???

I would imagine so, otherwise how can it know what TSR's can load-high or not.

I also remember that QEMM had some interesting Shadow Ram techniques for hiding VGA and other ROM chips in that not addressable area between 640k and 1024k range.

No matter where you go, there you are...

Yes, "RAM Boost" does scan your configs and then reboot, even if it detects that your configs have been edited. QEMM sounds very interesting. I wonder if it ever appears on ebay, from time to time? Was the very last version on 3.5" floppy disk, or did it ever appear on a CD-ROM?

There is something called QEMM97, which comes on a CD.

Only 'problem' is that it doesn't see memory over 256mb.
Tried installing in it on win98 (this is a win95 product), to get more conventional memory in the win98 'window DOS', without having to start in MS-DOS mode.

Seemed to work fine, though did affect a few things, which I now don't remember what was. Something related to when I used internet etc.
But was possible to start the machine without it, during boot you could press a key ('Alt' ?), and then choose not to activate the QEMM.

You can find some files here, qemm8 and 97(?):

Use an ftp program!
Then copy and paste the address above.
Never tried the files myself, so beware.

PS:
Been quite some time since I saw QEMM97 on ebay, a couple of years at least. The floppy versions occur from time to time (ver 7 & 8 ).
