Can't get PC-Check to boot

[eggbert]

I am having trouble booting a floppy image of PC-Check, a diagnostics program. It works fine using BCDW but I want to transfer it to a USB drive and BCDW doesn't seem to support USB drives. It works fine using syslinux/isolinux but only if you don't use menu.c32 or vesamenu.c32 - and I want to have some kind of menu system.

I have tried using the memtest parameters RAW, BIGRAW and SAFEINT but doesn't make any difference. Grub4Dos also doesn't work.

I am presuming that because it is a program that tests memory, it wants to use as much base memory as possible, therefore using menu.c32 or vesamenu.c32 just tips it over the limit, but I really haven't a clue.

Any ideas?
