I was previously running an P-133 in my machine with an HP 600Cse printer off of LPT1. I recently upgraded to a K6-233, and got a new motherboard to support it. With the change came the demise of LPT-1. When trying to load printer drivers, an error occurs in establishing communications, and the printer spits out a page with one line of meaningless text. When trying to install drivers for my parallel-interface Zip drive, the setup program cannot see it either. I've tried all of the port modes in the BIOS setup (Bi-directional, ECP, etc...), with the same or similar response. Suspecting a hardware problem, I exchanged the motherboard for a new one, which does the same thing as the first.
Offhand, I cannot remember the brand of the motherboard.
The serial port works fine with my mouse.
And, yes, the red stripe is at pin 1!
