Ubuntu install problems

So...got my 5.10 disks today and did a typical install on an older system (AMD k6/500mhz, 256mb ram/diamond 6 viper 16 mb vcard, etc). The install seemed to go well, got the partitions all set. Went to do restart after install, and now I get nothing but a black screen/blinking cursor after the vcard post. I can get into the bios by pressing f10, but I  can't see and post info (drives installed/mem test). So I tried to reinstall from cd, but it seems that it hangs before it posts and therefore never reads the cd drive/no hard drive activity lights. Any thoughts?

It sounds to me like the video card is in conflict with another piece of hardware. Check for a video card option in your BIOS. Is there integrated video on your motherboard?
