If you press F1 on boot to go into BIOS, you might (1) check to see if Hyperthreading is enabled - I couldn't get my RHEL to work with it off (disabled), similar problems to what you describe. (2) After Pressing F1, go into the system and post logs, and check for error codes. (3) Instead of pressing F1, try pressing F2, and go into the on-board diagnostics. the memory tests take a while, but otherwise it is fairly reasonable. (4) Do you have a RAID adapter in it && also don't have one of those otherwise fairly ubiquitous large plastic info panels on the INSIDE of the top metal cover. There have been problems where the cover shorts out some of the contacts on the RAID adapter. Some plastic and Duct tape usually fixes it. Good luck! <<<tt>Message: 3 Date: Wed, 6 Jul 2005 12:41:22 -0700 (PDT) From: Justin Reed <docpeppr@u.washington.edu> Subject: [rhn-users] RHEL 4 Install - Strange Behavior To: rhn-users@redhat.com Message-ID: <Pine.A41.4.61b.0507061223140.110344@dante65.u.washington.edu> Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed Hello, I've got an IBM eServer series x330 server that upon which I'm installing RHEL 4 Update 1. First off, when the installation asks to check the install media, the checks always fail. When I do the check on a different system I get straight passes. RHEL 3 had no problem. Second, usually when I boot the system (from CD or hard drive) I have to unplug the keyboard and plug it back in a few times to get any keyboard input working. I just tried logging into the installed OS and the keyboard input was either in all caps (without CAPS LOCK on) or resulted in "2", "'", and "~" characters, among others. Sometimes rebooting helps. Finally, the system refuses to reboot. When I tell it to reboot it goes through a normal shutdown sequence and the screen goes black but it never actually restarts. I'm forced to hold down the power button to get it to shut off. Has anyone experienced something like this? It's very odd and I'm at a loss of where to start. I've looked in the BIOS and AFAIK there isn't anything wrong. I'm also pretty sure I didn't tell it to install X, though it boots into it by default now. That could be negligence on my part, though. Thanks very much for any input.
