It does depend on the ability of the bios and the configuration. The setting is "status after power failure", which would be equivalent to a timer shutting off the power strip you have the computer etc plugged in to.
I have a number of machines here, and each interprets this in a different way. Some will start and boot up when power is turned back on, some wait for me to hit the power on soft switch. One will power up then hang before it starts the boot process.
At least with the old at style power supply, on meant on all the time and the above was trivial.
The big concern would be to get a clean shut down in windows, but there must be a way since win98 setup uses it. Another option is to use the timer to cut the power, then turn off the automatic scandisk on the assumption that nothing would be writing to disk
