Could anybody please tell me where I am going wrong. I am trying to upgrade the processor in my kids pc. It is a Colossus (Time) with a P5ST-A Mother Board (GMB-P5ST-A....2A5IIG39 Gemlight I have found out so far). The cpu is an IBM 6x86 PR200 (Socket 7). I am trying to upgrade to a Cyrix MII 333GP. When I install the processor, change the jumpers and switch on, it says there is a PR233 6x86 installed?? and locks up on the windows 98 logo screen. I tried flashing the Bios with a version which came on the "drivers cd" but that just seems to lock up and sit there. Is it a bios issue and I haven't got the right version or am I being a pleb and missing something really basic?? Any help would be most appreciated.
