Hello everyone, I apologise if this gets duplicated... I've been having sendmail and ISDN line problems here, that put together == intermittant mail failures. This was send out at 8:54 am CDT 23 may 97.
I'm writing a driver for some pci hardware and seem to have run into a problem. I'm kinda new at this, so I went to the kernel hacker's guide to read up on character devices. I got to the point about the outb and outb_p functions. In there it says that the port has to be a short. This is my problem. The card I'm writing the driver for puts its real registers out of the range accessable by a short. Here's relavent part of the <cat /proc/ioports>:
efbdc000-efbddffe: ihcp
That REALLY is the IO space for the card's registers. Am I missing something?
TIA Pat
