Just a quick note about something that has just cropped up: I was upgrading one of the really old machines at work with some PC133 SIMMS i found in another dead machine.
After upgrading the memory, it came up with an 164 Memory Error and wouldn’t boot no further!
Don’t panic though, it is just a bios message that tells you that the memory configuration has changed. All you need to do is restart that machine a few times and it will become happy with it’s new memory!
