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.

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
