I have Dell Optiplex GX 620 3.2 GHz 2 MB Cache, Philips CD/DVD RW +/-, 1 gb ram and 945g chipset. I am trying to install linux on my cpu. I have already tried three distributions, Ubuntu 5.04, Red Hat 9 and Mandrake 8.1. None of them works, the first two apparently due to cd rom incompatibility. Can you give advice on which distribution to install which will work with my system? Thank you
