Yes, we have changed this to use BIOS, because your original code
didn't work with the "floppy emulation" in the El Torito
specification. It seems that we should reconsider the floppy probe
technique. Perhaps the right thing to do is:
1) Call INT 13, AX=4B01 (Bootable CD-ROM - GET STATUS).
2) Check if the call succeeds.
3a) If succeeds, use the media type field of the Bootable CD-ROM
Specification Packet to get the geometry.
3b) If fails, use your original probe routine to get the geometry.
