Motherboard does not recognise CD ROM

I am trying to build a PC, my mobo (not sure what type but it supports PS2 K/B and Mouse and has Primary and Secondary IDE connections as well as Floppy) only has boot up options for Drives A and C, nothing for CD ROM, also on boot up, my CD is not recognised even though it is plugged in to the secondary IDE channel as master. In the BIOS there is an entry specifying what device is connected to secondary IDE, I have set this to IDE CD ROM - still no joy. I have used 3 diferent hard drives and using a 98 boot disc, F disk and formatted no problem - however I cannot then boot from CD to load windows. Can anyone out there help?

this could be an old bios problem. you may have to flash it. If you have the drivers try installing a dos driver for the cd. Also look in the bios for os2 op system and set for that, also set for pnp plug and play op system.

is there a setting for auto for the drive type in the bios, also check cable is correct ie: red stripe to power and jumpers are right ( normally centre for slave and the right pin for master )

It sounds like a very old Mobo. There should be a page in bios to auto detect the drives, if not try a double click on the drive. You have got the jumpers right I hope.

PS also try a different cable, red wire toward the power plug and pin 1 on the Mobo

Hears one not to use CABLE SELECT. Use Master and Slave as jumper settings

It sounds like a pre-pentium motherboard. Certainly one I had then, had a 486 CPU. The drivers for the CD (loading Windows 3.0) had to be installed separately.

No harm in experimenting but even if you load the generic drivers from a floppy, I feel this is the beginning of a list of problems.

Guys - Thanks for your thoughts, I have checked the cable exhaustively, I'm sure it goes deeper than that. I have loaded DOS driver, no joy - I'm going tp try to flash the BIOS as Howard 60 suggests but I'm beginning to suspect that it can't be done. Thanks again.

If it is, then why not connect it as primary slave to your hard disk drive?

If it is an old CD-ROM drive - and I'm talking really ancient - some of these had to be connected to the sound card via a cable. The best generic driver for these was the Creative Labs CD-ROM driver.

Tried your suggestion and wired it up as primary slave - still does not recognise it - thanks for trying
