First post, by freetmool
Hello, this is my first post (no pun intended), I'm from Belgium, born in 1979.
I like to restore old stuff and now it's my first PC from my youth 's turn 😉
This forum has already helped and interested me a lot by reading it, so thank you all !
I'll need some help because I've done many tests and I can't get my motherboard much alive...
First I didn't have any sign of life despite testing the PSU voltages (all good) and replacing the battery.
Plugged a VGA card, nothing...
I've tried many different BIOS and when I used the Phoenix one, I got 1-3-3 BEEPS
That seems to mean that there is a RAM problem.
So I've checked every DRAM with an arduino tester and found one bad one, great ! Well.... no.
Tried with one bank only and zero bank. All bank switches are in the right place.
Still the same problem.
Any idea ?
I should receive a diagnostic card soon but I don't think it would be much help from what I could tell.
Here is the motherboard in question: ( I do have the manual, bios rom and EMS diskettes if someone is interested)
