Hello everyone

Someone gave me an UC4915 motherboard wich wasn't used for 18 years. It has been damaged by a leaky battery so I bridged every damaged traces
There was also many missing jumpers so I looked at the manual here http://www.elhvb.com/mobokive/Archive/Ecs%20- … 4915/index.html in order to put all of them back
The bios had it's sticker missing, but apparently this mobo spent the last 18 years in a drawer, and I dumped it with uniflash and apparently the ROM is fine (Just note that the first half of the rom file is empty so don't worry if you're seing nothing at the begining of the file). Sadly I didn't find any dump of the rom file of that motherboard on the internet ...

And so, when I'm turning on the power supply, the cpu is heating, but I can't hear any beep, the screen don't detect any signal coming out from the vlb card and the keyboard keeps it's 3 leds on ...
I tested every parts and they are all fully functionnal, I also tried an ISA card just in case the VLB wasn't working anymore, but I got the same results

Here are some photos :

You may see a damaged trace in that photo that don't seem to be repaired, but in fact I bridged it from the other side

Thanks in advance for help 😀
