Fail to detect the Cd-Rw

[chindea mihai <misubs24@yahoo.com>]

Hy,

I tried to install the AMD64 OS version, on my PC, the boot worked fine, but when installer should Detect and Mount the cdrom, failed to detect any. I was wondering if there is any problem with my mainboard. I have an Abit Aw8-Max, a Intel Pentium D 830, and 2 optical units, a cd-rw and a dvd-rw both Plextor.
Can you please tell me what should I do, so the installer to detect one of my optical unit.

Cheers
