DW>From experience, the following chart shows how the BIOS

DW> 3 Ports 2 Ports 1 Port
DW> present present present
DW> ------- ------- -------
DW> LPT1 3BC 378 278
DW> LPT2 378 278
DW> LPT3 278
DW> OS/2 assigns IRQ 7 to LPT1 and IRQ 5 to LPT2.
Actually the IRQ is "assigned" to the I/O port.
Port 3BC and 378 use IRQ 7
Port 278 uses IRQ 5.
I have only one printer adapter installed on this machine.
It is called COM1, it uses IRQ5 @ port 278, and OS/2 loves it.
