I have installed a reset switch on my pc-compatible. (in 1/2 hour)
There is a 8284 clock chip close to the 8088 CPU, this chip
controls the cold boot reset ie. when you power up, this chip
sends a reset pulse to everything. You can force this chip to send
a reset pulse to everything by pulling its pin #11 low. This won't
harm your system at all since you are doing the same thing when you
turn your sytem on/off.
