@agranlund Ok, inserting the strange video card with RJ45 damaged the Raven. Initially it worked but now it freezes at boot and in coolterm it gives me this:
Examining the motherboard I saw this:
It seems trivial but I wouldn't want to have damaged anything else...

That looks like it's the +12V rail and I guess it must have shorted and burned that trace?
A good thing is that it's only used for the ISA bus and the two fan headers on the right side of the board so it's not like it's going all over the place.

If it's just damage to that trace where the picture shows then perhaps the two lower slots still work.
And the trace could be repaired or perhaps one could replace with wire going to the ISA socket pins on the underside of the board.

But if it was my board I would have wanted to look that area over with a multimeter and check anything which is adjacent to that 12V trace or pins on the ISA bus. In case something next to it has been damaged, or if even worse the damage has made 12V short to something adjacent.

+1 for metering out the tracks around the burnt track. It's possible it may be worse underneath that ISA slot.

Thanks for the advice. I'll let you know... ;)

I had the +12 track repaired and tested it with the tester, and there don't seem to be any short circuits. The video card works in the first ISA slot, but I have another problem: I have issues with various SD and CF, with any partitioning, with and without a byteswap adapter. Today I will do more tests...

Ok, I solved almost everything. I get little dots on the screen when I drag icons. :roll:

Having the same issue with my w32i
I think this started some weeks ago and changes from day to day (more or less dots)
Not only when moving icons, but also moving or resizing windows

Other cards, mainly non-accelerated ET4000AX or Cirrus are showing absolutely clean pictures (although being slow)

System is rock stable otherwise…

Before the accident he didn't do this.

I installed NVDI and the problem disappeared... :?:

@luciodra not sure if I remember correctly but did you have an NE2000 card which wasn’t based on RTL8019AS at some point?
If so I was wondering if you are maybe interested in trading it for a Cirrus GD5426?

I’m interested in making uip and the ethernec driver compatible. I have some hunch on at least one thing I think that code is doing which deviates from the standard NE2K way of doing it and with a bit of luck it’s just that one thing.
