I'm trying to reinstall CentOS on a machine I've reconditioned for it, but for reasons I can't fathom, when the installation disk comes up and prompts for the install type, and I type either <enter> (graphics isntall) or "linux text"<enter>, after it loads the initrd image, the machine shuts off. It's an older machine I built myself (and ran CentOS on for a number of years), AMD Athlon 64 x2, 2GB of memory, 2 SATA hard drives, ECS GE6100PM-M2 motherboard. I should probably even know the answer to this one, but I'm stumped. Any suggestions? Thanks.
