From my DMESG:

ide_pci0: <VIA 82C586x (Apollo) Bus-master IDE controller> rev 0x06 on pci0.7.1

wdc0 at 0x1f0-0x1f7 irq 14 flags 0xa0ffa0ff on isa
wdc0: unit 0 (wd0): <ST31722A>, DMA, 32-bit, multi-block-16
wd0: 1625MB (3329424 sectors), 3303 cyls, 16 heads, 63 S/T, 512 B/S
wdc0: unit 1 (atapi): <FX820S/g01>, removable, intr, dma, iordis
acd0: drive speed 1377KB/sec, 256KB cache
acd0: supported read types: CD-DA

wdc1 at 0x170-0x177 irq 15 flags 0xa0ffa0ff on isa
wdc1: unit 0 (wd2): <QUANTUM FIREBALL EL5.1A>, DMA, 32-bit, multi-block-16
wd2: 4892MB (10018890 sectors), 10602 cyls, 15 heads, 63 S/T, 512 B/S

DMA seems to be ON. But it didn't help :-(

Alex.
