The following PCI IDE drivers:
1. Promise UDMA33
This seems to work fine up to UDMA mode 2, so long as you can
confirm that your PCI bus clock is running at 33MHz +/- 2%.
(running at 30MHz like mine was is good enough for reading, but
corrupted silently on writing).
2. Winbond SL82C105
This is fine, so long as you don't use any of it's DMA modes.
As soon as you do, the chip appears to cop-out. I know that some
people are looking into getting DMA working on this again, but
current advice is not to use DMA on these devices.
3. Ali 15x3 (? or whatever it is)
No experiance of this chip - I believe Phil has some information on
this one.
