The A20 stuff that Syslinux/Isolinux (and MEMDISK) mess around with, 
even before loading a DOS kernel. As your driver expects a sane BIOS 
setting and sane behaviour of the DOS kernel, it's slightly less 
tolerant/paranoia compared to JEMMEX. This is all at boot-time 
(config.sys), not runtime (devload xmgr.sys) as no A20/HMA stuff is 
involved then due to DOS (kernel-)limitations.

Think I prepared a floppy image file sometime ago, but downloading that 
isn't very modem-friendly.

Basicly I just have to verify behaviour of different sets of drivers 
under various systems and emulators. It's a long-term todo item.
