CD-ROM problem (suspect BIOS)

[martypastor]

On my old computer w/c is the Samsung MA10.

I have a problem about the CD-ROM's
-Because there are 2 CD-ROM's Installled but the problem is that when i checked it at the CMOS, there is no CD-ROM installed.

So i checked the Power Cables, IDE Cables, Resetting the CMOS Data and arrange the jumpers. But nothing has changed.

Then I tried to remove one of the CD-ROM's but luckily one worked.
But when i put the other one back, all went gone (It means that when I checked it again, There are no CD-ROM's Installed.)

What Could Possibly the Problem?

and one question;
If the clear the ESCD Data what would possibly go wrong?

Thanks

Did you set both CD-ROM drives to Cable Select?
