    From
    Subject[OT] factory made but custom dual 8255 I/O card Q
    Date
    Greetings;

    I'm about to embark on a linuxCNC project, and I have the motors,
    controllers, and a futurlec PCI8255 card, with has dual 8255's on it
    for a total of 72 I/O lines.

    This card has a dipswitch settable addressing scheme that allows it to
    be most anyplace from 0000:0000 to 00FF:FF00 in $100 steps for the
    increment.

    When placed in the machine, the bios reports a resource clash, but
    gives the option of continueing the boot. Its got FC2 on it, clean
    install with most updates. I've tried moving the address but the
    bios still squawks, but it does go ahead and boot to FC2.

    Once booted, an lspci -vv doesn't output anything that looks like a
    resource clash to me, and while the bios bitches, its supposed to
    tell you what is clashing by putting a * in front of the two or more
    items at odds with each other, but those screens aren't actually
    indicating anything wrong. It also doesn't show this board in the
    bios displays.

    Can anyone comment on this?

    So my next Q then is, do we have, someplace I haven't tripped over it,
    a relatively simple, preferably timer IRQ driven assembly program
    that could be configured to drive such a board? The linuxCNC soft
    seems to favor a par port interface, but is supposed to be friendly
    to other methods also, how friendly may be discussed in the user
    manual, but it will be another hour + to get to that as its even
    pages are now just trickling out of the printer, and odd to go. 159
    pages total.
