I’m trying to make QNX 4.25 working on an industrial motherboard MB800H (www.ibase.com.tw/mb800.htm). I don’t have prior experience on QNX. So far everything runs OK (this motherboard is using Intel 845GE system chipset), except 4 serial ports can’t work. The serial port 1 & 2 are from I/O chip Winbond 83627HF, while 3 & 4 are from Winbond 83877. I’m wondering if there are existing drivers available? All feedback/comment/help are appreciated.
