Hello Thomas,

Off the top of my head, I'd suggest the memdisk from syslinux 3.83.

For some reason, I've always had better luck booting iPXE's
memory-mapped ISOs with GRUB4DOS. I'm not sure of the exact command
syntax, but it's something like "map (rd) (cd0); map --hook; root
(cd0); chainloader +1; boot;"

It may be (cd) or (cd32) instead of (cd0), and rootnoverify instead of
root... Might also need a "cdrom --init" in there too... It's been a
while since I've had to do this ;)

The readme file should provide some insight, of course!
