The board can be configured to use high IRQ, AND that the four ports share one IRQ. OS/2 sio driver instructions file, says it will work sharing IRQ's under sio. Also, shared IRQ work in "polled" mode serial lines under Coherent 3.1. Now the question: Does it also work under BSD ?? If working with another I/O board 2S 1P in irq 4 and 3, BSD would accept to compile a kernel using 6 com ports, IRQ 4, 3, 5, 2, 15 and 10 or 12 ? Would it recognize if changed to a different port address like 1F8 or 1E8 instead of 3F8 OR 2F8. I would rather learn from your experience than testing all these possibilities. (I only want to have 6 serial and 1 parallel working ports). Thanks Bernardo Brummer bernardo@prevfogo.ibama.br
