From the 1st CD, Rescue CD (or any other CD that has it), or 2. From Grub if you have installed it. Memtest86+ runs as a completely stand-alone program. On any new box that I use, I try to run it at the first opportunity that I get. (I usually let it run overnight, if not a week-end.) Of course, sometimes given a new "play toy" I don't always get around to running it. *However*, if the box ever starts showing "weirdness" (and it's not obvious what's wrong), this test gets scheduled at the next "slow period" for the unit. You'd be surprised the number of times it finds things -- even with ECC, registered memory, etc. (Of course, it is *not* a panacea for all system ills -- just a tool and one of many ....). I now typically try to install it on all of my servers so remote techs can run it on units via grub without having to find / have a CD. The reason that I recommend checking the version of the BIOS, I have found "with the latest & greatest" it sometimes helps. The last time I played with ASUS motherboards (many years ago) I found that you had to be on 4th or 5th release of the BIOS before things really go stable. [OT: I recently installed a dual Xeon system and was having lots of problem. Given that it was recently manufactured I figured everything would be up to snuff on it ... Nope -- it needed a new BIOS to work with > 4 GB of RAM correctly.] However, since your system is booting and working, I would conjecture that everything is fine and should be able to work and use the system. Do a "yum update" and make certain that all things are installed (and up to date). Have fun ... Rich -------------- next part -------------- An HTML attachment was scrubbed...
