Hello,

I just got an IBM PS1 2133 model 174 in rather terrible condition, an I am not attempting to restore it.

I have connected the motherboard to a vga monitor and got the following errors at startup:

000000 AA55 201

Then, I removed all of the ram from the board, and the error code changed to:

000000 0001 201

Is it an issue with the onboard ram? Any way to get around it or do I need to start looking for new ram chips?

Thanks.
