If you want to get your hands dirty, and solve a right-now-outstanding bug without getting bogged down in the ongoing architectural debate, there is a defect in the current pccardd program relating to the allocation of memory mappings from the card to "real" memory. The pccardd code assumes that all mappings will be multiples of 4k; this is invalid, and results in regions that are > 4k being slightly truncated (this is rare), and causes any card that has a region < 4k to result in a requst for a window of 0, which fails and causes the card to be rejected. The "simple" fix for this is to round any request < 4k up to 4k. To implement this, you will learn a little about the workings of the current pccard code, which will prepare you for more work there later as we try to design an architecture that handles this better. You'll also be appreciated for the work by lots of people with these cards that can't currently use them. > BTW: Thanks to all that helped me get my 3com ethernet card working, it > was the interrupt addy, I changed it to 9 and it WORKS!
