Look online for a manual for the mb. Often there is a reset jumper, if nothing else, historically it was number 5.

Hi Gus,

First thing I would ask is .... How much more speed do you need ? 

How many boards do you want to modify ?

If it is BGA, then heating up the chip and "Suck-tioning" it off might work.

( If you have a sacrificial board , I would try the removal for you )

Have you considered overclocking the board ?  ( while cooling the board with TEMs ) ?

Do you have a schematic of the board ?  Not all PC104 and PCI connections are made equally.

Well we'd like as much speed as we can get.  I think realistically without active cooling we wouldn't be able to get more than 2x the current speed, with something like the Winchip or the Via 586 type CPUs or whatever they had that were 486 pin compatible.

We have 500 of these boards, if the modification was successful we'd do 200 or more.  It's an industrial embedded board and system failures are Bad News so I would be really hesitant to overclock.  Cooling is an issue, and it'd be good if we could get away with using only the passive heatsink like what's on there now.

We have lots of failed boards that are good for target practice or soldering practice. :)  Send me your info offlist and I'll send you a board and PO or whatever  you want to do.

Thanks,
Jim

Hi CLUEbies,

I'm grasping at straws here but thought I'd see if anyone out there has a suggestion.

We have a single board computer with a 486DX2 chip on it.  The board is end-of-life and the CPU is soldered to the board (probably BGA).  There are PC104 and PCI connectors on the board.  Can anyone thing of any way we could keep using this board for a little while longer (until the R&D is done on the new system architecture) but with a faster CPU?

We think we remember seeing (long ago) CPU or coprocessors you could put in an ISA or PCI slot or something.  They would either coexist with or replace the CPU, or something.  Does this ring a bell with anyone?  Can you suggest any way we could get the board to be faster?  We tried & won't be able to desolder the 486 chip to replace it with a faster chip.  If only it was a socket!

ObLinux: the OS that is on the hard drive for this SBC is Red Hat 7.2.

Thanks,
Jim
