yeah, i forgot to export that in my patch.

So, IO_BASE = 0x80000000 does work, ll_rw_blk.c is an unrelated bug.

It may be a little confusing, but since it works for me I doubt there is a
goof up. The confusing part is that there is code in there to bypass card
services for ATA cards. Instead of deleting it, I left it so that people
who don't want the overhead of card services (my guess is that it doesn't
really affect perfomance that much) don't have to use it.
>Does anyone have a patch for this file?
you have the patch that works.
>Also, what should be the values in the config.opts for this?
config.opts is not used for the 8xx.
you can send me a microdrive and I will figure out what the problem is.

I don't think Dan uses card services. He has code in the kernel that
connects the ide driver directly to the 8xx pcmcia controller.
