I'm not sure if I can duplicate my prior errors to be sure but I had a super smooth install (finally) using Redhat 7.2. I'm pretty sure it was the memory ( thanks
www.memtest86.com). In addition, I unplugged my CR burner, and USB Sanddisk (but I doubt that was the problem) The memtest86 generated a lot of errors on my two (apparently mismatched 128 K RAM). I put in some new Viking Ram and voila, install. The install was complicated slightly by failing to recognize the ethernet cards. I rebooted and swapped out the netgear FA311 NIC. Redhat found the DFE-530TX. I have a DSL and had to refer to my Redhat Unleashed to do a command line ifconfig. I still haven't gotten the FA311 to be recognized (but that's fodder for a another thread if I can't do it myself). Thanks to everyone for their helpful advice.
