I would like to get some explanation on PCI-IDE interfaces. I have a
National Semiconductor PC87410 in my portable. I do have the impression
that my harddisk is not running at the speed it can run. It supports PIO
3 and DMA. Now, the NS87410 doesn't support that (the NS87415 does
support that, and there's a driver for that in the kernel). I got the
docs for the NS87410, and now I wonna know how to read the PIO/set the
PIO. Now, I guess I just have to adjust the timings, but to which value?
And second, how do I change the values (can setpci do the job? ...)
Anyway, if some IDE-guru can give me a little bit of help or explanation,
that would be great.
