old 486 and dual ide controller



New Member
I'm trying to get an old 486 board, 30 pin simms, vlb, working with two hard drives and a cd-rom. No matter what I do I can't get two ide ports working. I've tried different controllers, disabling the secondary controller on the vlb, and putting a dedicated ide controller on. No luck. Nothing is working. Is there a limitation on some old motherboards in respect to ide controllers so that the board will not support dual ide?

Any help most appreciated.

All's well that breaks well.

If you have 2 IDE plugs in your I/O controller, the second one is only for ISA stuff, you could only put there your CR-ROM. You will put both Hd in the first plug, with a two-pin fat cable.

don't forget to enable the secondary IDE in your bios! I did the same thing when I installed an LS-120 drive (a great device). I had to enable the secondary IDE port in my AMI bios. Good Luck.
