I recently took some cards out of an old 486 and there was a ISA CD-rom interface card, and I don't know what it is, and it doesn't auto detect. It doesn't have any internal plugs only an external one which seems like a SCSI 1 port.
Its has the numbers F12V-0 399306, CD-IFI4-A and a NEC chip on it. Doesn't ne1 know where I can look up these manufacturer numbers so I can find out what card it is
