I ran across an old diehard BH6 with a Celly 300A. Put it together and tried RedHat 7.2 install. Failed at kernel install. Tried Mandrake 8.1...same thing. I tried this with the ram in different banks. I tried it with a good PII 233. No dice, not a successfull install. My other two components are in known working condition: Ati Rage 4mb PCI, Seagate 8 GB hd, and Mushkin PC100 256 MB. Here's the kicker! I installed W2K twice. Ran Prime 95 for hours. Same thing with SiSandra...burned in for hours. Very stable machine! Anyone have a clue?
