Simply won't work booting the floppy disk image via MEMDISK.  In the interim, I've tried to resolve this by changing things on my side.  I'm pretty sure it's a XMS incompatibility, as it fails differently depending on which of three diff HIMEM drivers I use.  I've even switched from using a Win98 boot floppy image to FreeDOS, but no joy.  Whatever the prob is, it's weird bec launching this disk image as the CD bootstrap works flawlessly and has done so for years.  But, if you boot the image via MEMDISK, even after making it all the way to the DOS prompt (where supposedly MEMDISK is completely out of the picture), Doc Mem consistently craps out.

MEMDISK isn't out of the picture as long as you're still accessing the
"disk".

It's quite possible Doc Mem overwrites MEMDISK, despite MEMDISK's best
efforts at protecting itself.  Other options, of course, is usual (try
raw, bigraw, etc.)
