Hi,
I have an IBM PS/2 55SX that is displaying an error while booting. The PC beeps twice, displays 161 and 163 on the left hand side of the screen. Across the top of the screen is a large red equals sign, followed by “OK” in a red circle with a line through it, then a white arrow pointing to the right, then a picture of what looks like a simply drawn book with IBM written on it. Can anyone tell me what this means? The only indication I can find online is that two beeps means “system board” but that’s not enough information for me. Any help anyone can give will be very greatfully received.
Many thanks
MZ
