Hello, I want to use an ISA card in my 715/50. It fits in the expansion slot, that's a good beginning. I have to access the card by simple reading and writing to an I/O port.
If I install the card in an x86 based PC, the addresses are in the range 0x300-0x303. In fact, it's just a simple 8255 that I have to access. In an 80x86 system I access it directly, without a kernel module or using /dev/port. How can I access this card on my Apollo? I am not capable of writing a kernel module, so if it is possible to use /dev/port it would be great. On what address do I access the 8255? Thanks in advance for your answer, Roland Leurs
