Ok, here's the story. I have just been given an old computer to "fix" and so i open it up and can hardly believe what i am seeing. I have never seen a motherboard like the one this is using, and i have absolutely no idea what it is, so i am hoping someone might recognise it from this description. I'd be very grateful if you could help out...
The first thing you notice is the size, this motherboard is HUGE! It practically fills the entire panel of the case it is sitting on. Also, it is on the opposite side to where motherboards are housed in modern systems, if you are looking at the case from the front, the motherboard is located on the left hand side, not the right. The real panel is like very elongated ATX panel, and includes (from top to bottom), serial port 1, serial port 2, 2 USB ports (next to each other), VGA port for onboard video (more info in a moment), PS2 keyboard connector, PS2 mouse connector, printer port.
The board is for Slot 1 processors (currently housing a P2 266mhz) which is located at the top left hand corner. Next to it, in the right hand corner are 8 ram slots for EDO or Fast Page ram. The integrated video comes in the form of a Matrox vga chip, i'm assuming Matrox Millenium onboard, probably 8meg at the most. It also has onboard sound (no idea what codec or sound chip) and onboard LAN which comes in the form of a small additional board which is connected to the motherboard and fits on the top right hand side at the rear of the case. The onboard sound works in the same way, a small additional board that connects to the motherboard and fits at the rear of the case at the top right hand corner, next to the LAN "card". The power supply is fitted about half way down the case, but the board design seems to have this in mind as it does not obstruct any ports or slots.
Closer inspection lead me to discover that this board is effectively in 2 halves, as if the northbridge and southbridge or on 2 seperate PCB's, connected by 2 (maybe 3) long connectors. The bottom half of the board houses the PCI and ISA slots (no AGP) and they are arranged in an unusual way, (from top to bottom) PCI, ISA, PCI, ISA, PCI, ISA, ISA. The power connector is a standard ATX power connector, located just above the first PCI slot. The 2 IDE connectors and FDD connector are to the left of the PCI/ISA slots, though neither of the IDE connectors were used on this system, it was using a SCSI hard drive via a SCSI adapter card in one of the PCI slots (no onboard SCSI that i could see).
The chips are all marked Intel (with the exception of the Matrox GPU chip), and i am assuming it is using an Intel chipset.
Does this description sound familiar to anyone? I am completely stumped, if anyone could shed some light on this, i would very much appreciate it. Thanks in advance as always...
