I've got an EISA motherboard with the marking:

  SFL40V0

on the back and the marking :

  4SLUD 1.1

which has a UMC chipset and AMI BIOS.


The board has a soldered on 486SX/25 and a socket for a second
processor.


I've added a DX2/50 to the socket for the second processor and the BIOS
recognises that a coprocessor is installed and the Intel diagnostics
confirm that a 50 MHz CPU is installed.

SADLY, when the new processor is installed, the Norton Utilities CPU
benchmark falls from 54 to 11 and doom runs a lot more slowly !  Looks
like I need to mess with a jumper somewhere but I have no documentation
telling me which one.

Can anybody tell me how to get the DX2/50 recognised at full speed ?


Cheers, J/.
