The BIOS I think is irrevelant - I've put 48x IDE CD-ROMs in '486 without
any problem.  BIOS support is only needed to boot off the thing :)

You should check to make sure the hard drive and CD-ROM are jumpered
correctly - ie HD needs to be set for master and CDROM for slave.

I've got a whole box full of ISA Intel and 3com ethernet cards if you need
any :)
