Seems to be a Anigma lp4ip1. Not finding any manual. Still, what I really need is to know how much CPU it can handle and need to know where to put the L2 cache.

I don't see any VRM hardware, so CPU is limited to 5V.

Apart from that, interesting video memory/cache layout. The four DIPP chips above the CPU are 45ns DRAM chips, i.e. video memory. But.. the two DIPP sockets next to them are labeled "dirty" and "tag" so are for the cache system. So I'd guess the cache itself needs to go into the four DIPP sockets to the right of the VGA chip and you need to populate the other two as well.

Here is an old page that has some information and contact info to get jumper settings, etc.

Please insure you have the
Anigma LP4IP1 before using this disk. GW2K has used several other
Anigma boards with similar names and numbers.
This motherboard is identified by the presence of the Intel Aries
chipset (82425EX and 82426EX chips), 3 SIMM slots at the front of
the board, and a double PCI slot supporting a riser card with ISA
and PCI expansion slots. The model number LP4IP1 is silkscreened
onto the underside of the board. This model number may also appear
on a bar code sticker along with the serial number. The Gateway
2000 part number for this board is MBDPCI004AxWW. This board is
also called the Aries Integrated.
