Just picked this board up at a swap meet. Can't find any information it but it looks to be a 386/486 board. Has 4335cl-p103 as well as fu yu 20 v0 printed on the back.
The SiS 85c401/402 chipset points to this NOT being an EISA board. The slots are likely a 32-bit proprietary local bus of some sort. Do not attempt to put a real EISA card in those slots, unless you want smoke.
Here is a similar board noting the local bus: http://www.funkygoods.com/mb/lc486c/lc486c.htm
Im pretty sure I have the same board, at least the two 32 bit slots looks exactly the same and the layout is very similar, its stored away at the moment though.
I know nothing about the board and I have never used it.

🙁 well that would suck. I did also pick up what looked to be a eisa et4000 video card that was in the same box but I suppose there's no way to actually know it it's eisa or whatever this board may have.
There is an "Opti Local Bus" that used the EISA edge connector as well that the ET4000 card likely went to. Obviously those boards used Opti 486 chipsets. I don't think any real EISA video card used a Tseng video chip.
Hmm the board and card cost me roughly a dollar. I may just stick the tseng card in, cross my fingers and see what happens. Unless I can somehow positively identify the board and card.
EISA Tseng 4000s did exist according to this benchmark review:
https://books.google.co.uk/books?id=IuaYd-eFa … g%20eisa&f=true
... Made by Orchid. If there's any consolation to frying the Tseng, well, it's not much faster than the ISA version!
i guess its a moot point, cant get the board to post. its kind of odd that the entire board only has 1 jumper and its to select either 486sx or 486dx. I'm pretty sure its a RAM error. I get 3 long beeps, its an AMI BIOS and 3 short beeps is the code for ram error...to me its 3 long beeps cause its like beeeeeeep (10 seconds) X3 but since there is no error for 3 long beeps i'll just assume my and ami's definition of short beeps is different.
the FCC id on the tseng card is ia6et4kvesa32k
its there but I couldn't get anything useful from the information.
does anyone know what the "CPU Upgrade" socket it for? they never made a 487 did they? the box with this board also came with the 25mhz 486 and a 30mhz 386 but the 386 is to small for the cpu sockets.
*NM, apparently there were 487's*
