Hi, need any info on jumper settings for this motherboard from Jetway, model J-426B (Ali M1489 A1).
It's configured as it came to me, with a 486DX4 120. Figured out the reset and power led for front panel.
Can't find manual online anywere.
Thanks.

You could probably do what I did when I got my first 486 motherboard, which is try different combinations until it works 🤣

Not really a good idea if he changes cpu voltage to 5v when using a 3.3v cpu, like the DX4 🤣
Otherwise, sounds good to me. I know 486 are sometimes difficult to configure. Many parameters to discover related with cache modes, memory, etc.
It looks similar to this one
http://motherboards.mbarron.net/models/486pci/ts486.htm
and that TS-486-1.1 has some jumper settings listed ---> here <---
So maybe that's a starting point.
