Problems with a new PC

I got myself a new PC today, an Acer Aspire L5100 with 4GB RAM and 640GB SATA hard disc.

Unfortunately, neither my Live CD nor some (relatively old) knoppix or SUSE discs that I tried could see either disc drive.

I'm sure I can rectify the situation, but I thought I'd mention it in case anyone tries the ISO image on a similar machine.
