on the MB it says (on a sticker)486SX /DXC64-LPX
ST11358557
Chipset:symphony(made in japan)
SL82C362(could it be a OPTI?)
Another chipset SL82C461
What i look for is the manual for this board because it has dual procesor suport or at least it looks like this since it has two proc sockets!!!!I want to put another proc on it but i do not know how because if i put one the system hangs maybe i should change the jumpers or something i reallly have no clue
Oh and the Bios it's a Quadtel
thank you
Alex

Hi

There are no dual boards in the 486 class.
What you have there is a socket for a 487 numbercruncher when using a 486SX.
Forget about all that.

So, only if you have a 486SX installed, get a 2nd Hand 486DX and install it into the socket, where the 486SX resides.
You need to move 1 or 2 jumpers for the DX to work then, and yes, then we need the BIOS-ID as mentioned before.

If you already have a 486DX leave it as it is.

Hi

We are talking about ordinary PC Hardware here.
There were simply were no dual boards in the 486 class.
The first Dual stuff for street market appeared with the Pentium, when intel built the basics for dual CPU support into the CPU.

PS.: We had some Siemens MX500is at work, and yes, they had several 486DX CPUs built in.
