Jim,

Many (most?) cdroms from 486 era PCs used proprietary interfaces and were
not true IDE devices.
Make sure the CD is an IDE device.

Subject: [PCBUILD] PC Upgrade


Hello,

I have just upgraded my old 486 DX-33 to an MMX-200Mhz. The new CPU is
mounted to a VA-503+ Motherboard from 1st Mainboard. My problem now is that
I cannot recognize my CD-ROM as either Primary slave or Secondary Master.
System hangs once the screen shows BIOS manufacturer and version (award). If
I remove the CD-ROM, system will boot. I suspected Sound card at first, but
system boots with all cards in place! I changed CD unit with a known good
one...same problem!  Could the problem be with the motherboard? Is there a
jumper setting to enable the secondary IDE? Board shipped jumpered to the
ATX format and I changed power and CPU voltage to the appropriate jumper
settings. Maybe problem is with the power supply? Any suggestions? Thanks
everyone! Best regards,
Jim Phillips
