Hi all!
I still struggle to get this (see below link) MoBo to even show any POST code.
https://theretroweb.com/motherboards/s/biosta … 3F-umc498f-2vlb
PSU is good. I checked with another 486 based MoBo and that one boots OK.
I checked CPU voltage and Clock. Both good, 5V and 33MHz. CPUs I'm testing are: Intel 486DX 33 and DX2 66.
I removed all CPU configuration jumpers and tried a few settings I found based on some information I found for Intel DX/2 CPUs ... no difference.
The BIOS should be OK too.
Since there is not too much, actually none, documentation and BIOSes for this MoBo available ... I'm not sure what to do next.
Anyone any advice? Thanks!
