[newbie] RAM Disk Error

[Rem]

I have had a very odd problem:
I have a computer, with Athlon 700 Mhz, 30G HD, and 512MB RAM. I wanted to
put Mandrake 7.2 on it and it will give "ramdisk error" (It can not generate
the ramdisk) at the begining of installation and quit. Any idea why?

The oddest thing perhaps, is that i didn't have that odd problem when I used
another cd that was burnt earlier to install the system...

Any comments are welcome.
