A friend of mine returned his AT clone back to the store for warrenty repair.
The owner told him that he would have to buy a new mother board.  He said the 
mother board had smoked because two boards were set on IRQ 4.  He said it also
destroyed the hard drive.  He now refuses to fix or return the PC to him,
says he may need it for evidence.

I have installed boards with conflicting interrupts before and other than 
software problems, there was no damage.  The interrupt chip is just a
TTL input and shouldn't care how many highs are put on it's input.  I think
my friend is getting the screws.

Comments please!
