I don't know about exactly Your hardware, but - from my experience -
there are configurations where the mainboard chipset does not provide
enough power for the ISDN adaptor. - Although this problem should only
concern older ISA cards on older EX/BX chipsets, I'd recommend cross-
checking this one.

As for remotely cold-booting: With ATX, You can specify a "wake-up"-
time in most recent BIOSses. - But once the thing hangs, You cannot
even shutdown. Plus, it may be 23:59 hrs to the next wake-up hour...

In this case, get Yourself a proper "watchdog" card. - It will detect
system hangs and initiate a reboot, cold or warm.


Cheers, Jack.
