How to connect a CD-ROM to an old 486?
Posted on 1998-02-27
I've got an old 486DX/50 Mhz lying around that I want to upgrade a bit and give to my son to play with. I recently replaced the old 4x CD-ROM in my Pentium system with a 24x, and I want to install the 4x in the 486. The IDE connectors on the motherboard are in use (by the 3.5" floppy drive, and the 528 MB harddrive), so I got hold of an ISA IDE card to which to connect the CD-ROM. There is already an available power cable.
So I hook everything up and boot the system, and I get a Drive 1 error message. Then I get a message which asks me if I want to go into Setup or press Enter to continue. The same thing happens whether the CD-ROM jumper switch is set to master or to slave mode. It appears to me that the boot process thinks I am trying to add a second hard drive and is looking for me to specify the drive type. I tried changing setup to Automatic Detect on hard drive 1 (the second hard drive), and that didn't work either.
I'm thinking it shouldn't be this hard to install a CD-ROM. Do I have to replace the BIOS chip (flash BIOS this isn't)? Am I just doing something dumb? Should a get another IDE cable with 2 connectors, forget the IDE controller card,
and connect both the existing hard drive and the CD-ROM to the the IDE connector on the motherboard? Any thoughts or suggestions out there?
