I have seen cap failures do strange things like this; once I was troubleshooting a radio station automation computer that passed POST and several diags but would hang going into Windows XP (it hung going into a liveCD of a Linux distribution, too, so it wasn't Windows' fault). I asked the DJ if anything unusual had happened when it first locked-up, to which she said, 'well, not really, except that gunshot I heard.' Turned out a capacitor had shot its casing with enough force that it dented the steel case cover; but the machine would run fine until enough power was being drawn to shut down the regulators. Again note that this machine not only passed POST but also memtest86. > ---- > CPU card #2 > RTD cme37786hx > http://www.rtd.com/manuals/archive/archive.htm > http://www.rtd.com/manuals/archive/CME37786HX.pdf pdf page 14 has specs. > VIA Eden CPU with Twister-T Chipset, 400 MHz to 1 GHz clock speed > The VIA Eden isn't officially support, but yours appears to have cmov, which is the usual problem with them and CentOS 5+. I haven't personally tried an ISA-capable motherboard in a while with any modern CentOS......
