Hello,everyone
This is my first post. I'm new here.
In these days, I bought a 5160 motherboard. It cannot enter the normal display state (but there is a signal on the data bus). I tried to troubleshoot the problem and found that many circuits were disconnected. However, it still does not work after connecting. The ROM address is found stuck in E188 through the test. After checking the Technical Reference, it is found that it is stuck in code C24B (page 5-117), which is about memory work. I changed the BIOS to skip this step (I'll see if it's the problem caused by this step), and it didn't get stuck at this address. I'm sure it must be a memory or memory circuit problem. So I tried to replace the memory chip and replace it with the original BIOS, and found that it was still stuck at this address. However, the motherboard has no circuit disconnected. How can I troubleshoot the chip next?
Thanks for any help with getting this computer working again!
