Thank you for responding to my question. I tried what you suggested and more without luck. I got as far as the post install configuring before the crash sometimes. Usually ended with a Signal 11 error. I also worked with RedHat tech support. They were useless! The guy offered little beyond the install guide. I think the problem is with the Anaconda install program.
After 3 weeks I gave up and installed Debian. It installed OK.
I'll remove this thread if I can after you read this. Then I may start a "RedHat Sucks" thread.
