Furthermore, I wonder... If QEMU doesn't support this, and installing
Windows and other operating systems off CDs works, will many BIOSes
support this interface at all? PHOENIX BIOSes should, IMO, since the
ElTorito standard is made by PHOENIX, but what about the others?

We might have to read the boot catalog manually, not with the 4Dh
function to achieve more compatibility. Tonight I'll try to do an
"Extended Read", function 42h, to get the boot catalog and parse it in
a structure and see if it "makes sense".
