The PloP iso didn't work with MEMDISK 3.84-pre4.
After I compiled MEMDISK with the 2 patches added after the release of syslinux 3.84-pre4,
it did work great :-D.

I also tried Dell diagnostics (iso with a hard disk emulation boot sector) in qemu
and it looks like it works. I don't know any other iso's that use hard disk emulation.
