Is this patch available somewhere, or could you send it to me? I have the
same chipset on an Asus Athlon mobo:
atapci0: <SiS 5591 ATA33 controller> port 0xd800-0xd80f at device 0.1 on pci0
And yes, Linux can run it at UDMA100, and the printed datasheet of the
board says it's an UDMA100-capable chip. (The SiS doc says UDMA33).
Thanks
