[PLUG] Computer Case question:

[John Cirillo]

I don't have any dual-boot NT machines with a temp monitor so I can't test
this easily, but someone once told me that the excessive CPU heating caused by
Windows was because of the way DOS hammers at the interrupts.  My guess is
that NT or Win2k doesn't do this since it doesn't have a DOS core. 
If you had a way to monitor the CPU temp in DOS and could boot a DOS floppy,
you could prove or disprove this.  Not that it matters much, I guess...

Cheers,

John
