would a 64bit MEMDISK solve this issue? Or is the system then stuck in 
64bit without being able to return to 32bit/16bit? (or the final booted 
OS can't find MEMDISK anymore then I guess).

ah that's a usefull hint, thanks.

That's an option indeed. I would prefer to be able to mount uncompressed 
ISO's though as not all software supports compressed files.

syslinux -> memdisk -> test.iso
syslinux -> chain.c32 freedos -> isomount test.iso

I'll bring up subjects like compression, syslinux/memdisk A20 trouble 
and the DOS installer in a different mail sometime, lots of things to 
test/confirm first before requesting the attention of list members.
