TK 8881 FA20 = TB-486-OB = TD-4IP-UMC-AIO

I got TD-4IP-UMC-AIO board. It looks exactly like one of the ADI boards at Edwin's page.
The only exception are the fake cache chips with "WRITE BACK" on them.
Fake cache chips removed:
The BIOS had 27C1024 printed on it, nothing else - but it showed "Updating ESCD... Success" before boot. After rubbing with alcohol, the 27C1024 text disappeared and something other appeared. Again some rubbing, the second text disappeared too. Looks like there's Winbond there - but very well covered
The BIOS ID string is "12/19/95-UMC-881E/886B-2A4X5CF9C-00" and some sites dentify it as FordLian 9885AW board.
I'm going to install sockets for real cache there. I also want to make UniFlash support for the UMC chipset...too bad that there aren't any datasheets
