I'm trying to set up an ISA multiport serial card to run under Linux,
specifically a Digi Classicboard 8.
I have done this elsewhere with some success in an old box, but I cannot
seem to get it to work on a more modern mobo. I don't know what the exact
brand of the mobo is, but it has a VIA chipset.
To get this serial board configured you need to boot the box with the
driver disk that they supply. If I put the card in the new mobo then the
drivers don't find it, but if I put the card in an old mobo then the
configurator finds the card and I can set it up to the irq/ports (io
0x200-0x238 for the ports and irq 2 and io 0x240 for the control) that I
want and save the settings onto the card.
When I put the, now configured, card back in the new mobo, having
previously run MAKEDEV to create the /dev/ttyS* nodes for the extra ports,
when I run setserial to bring up the new ports in the kernel to match the
on-board setting, setserial complains that there is no such device for the
eight ports on the card, as if the new mobo is still not seeing the card.
I don't have an irq conflict and I don't think there are any odd settings
in the BIOS, besides which my understanding is that Linux doesn't take too
much notice of the BIOS anyway, so it seems that the problem is down to
the board.
Has anyone seen this odd behavour before, or have a solution.
BTW, seasons greets to all. I'm off to Singers for a few days in the new
year so if anyone wants me to bring back one of those Celestix boxes that
were being spammed the other day they had better send me their money PDQ.
