[clue] [TECH] PC104 or PCI replacement/upgrade CPU board?

[Alex samide]

Are there options for daughter board processors that the system has a jumper or BIOS setting to disable the existing, or at least double existing processor power?

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

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?

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!
