- I'll restate what I started with...it was cut out.
- Using Boca I/O 2by4 (4 com, 2 lpt) following configuration
- is ON THE CARD.
- COM1 irq4
- COM2 irq3
- COM3 irq2
- COM4 irq5
- LPT1 irq7
- LPT2 disabled
-
- I asked two questions. One about IRQ2 and OS/2 reporting that the interupt
- wasn't there, and the second was if I could run LPT1 and LPT2 on IRQ7 in
- OS/2.
