I'm not that familiar with DOS drivers.  You could try asking on the
freedos mailing list.  You could also try running seabios with
"-chardev stdio,id=seabios -device
isa-debugcon,iobase=0x402,chardev=seabios" and see if any interesting
debug messages come up.  Finally, one could recompile seabios with
higher debug levels to try and track down which calls aren't working
(if you suspect msdos should be seeing the cdrom).
