16 bits only because the harddisk only exists through a bios hook. In
32 mode windows bypasses the bios and talks directly to the hardware. In
the memdisk case, that hardware doesn't exist!

But maybe it supports some form of memdisks (like microsoft's

Aren't there some projects on the Internet about making windows 2k/xp
boot on a cd?
