I have a motherboard with the VIA Apollo VP1/VPX chipset which is
supposed to support UDMA, and a Quantum Fireball that also should do
UDMA. But the UDMA never has been working, it seems. Upon boot, the
kernel says:
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x6000-0x6007, BIOS settings: hda:pio, hdb:pio
