Hi

I have to used a TK8880F-2066 motherboard, 486SX-33 and 8 MB FPM, without any problem since a while.
Video card is a simple Trident TVGA-9000 ISA 512K.

I decided to try some other CPUs that I know working on other motherboards as well.
I tried :
- AMD am486 DX4-100.
- Cyrix 5x86 100
- Intel 486 DX2-66
- Ti 486 SL-50 and SL-40

I tried MANY settings.
I NEVER get success to get those CPU worrking on the motherboard since I changed settings 🙁

The problem is always the same whatever I put on the motherboard :
It freezes about 30s to 2 minutes after booting.
I don t understand what is causing now this random freezing.
Freezing also comes IN the bios while loading settings, randomly.

Can I ask you trying to help me get this motherboard working ?

I can't find any precise information of jumper settings, some of them are directly printed on the motherboard, but I'm not sure of the jumpers positions.

Memory I use :

Here's charts settings :

My settings for the AMD cpu :
