I used to be able to get >3MB/s with an old chipset and plain K6, now with ide_pci0: <Acer Aladdin IV/V (M5229) Bus-master IDE controller> rev 0x20 int a $ wdc0 at 0x1f0-0x1f7 irq 14 flags 0xa0ffa0ff on isa wdc0: unit 0 (wd0): <Maxtor 71626 AP>, DMA, 32-bit, multi-block-32 wd0: 1554MB (3183264 sectors), 3158 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (wd1): <Maxtor 71626 AP>, DMA, 32-bit, multi-block-32 wd1: 1554MB (3183264 sectors), 3158 cyls, 16 heads, 63 S/T, 512 B/S wdc1 at 0x170-0x177 irq 15 flags 0xa0ffa0ff on isa wdc1: unit 0 (atapi): <LS-120 COSM 02 UHD Floppy/0271C09T>, removable, iordy wfd0: medium type unknown (no disk) wdc1: unit 1 (atapi): <NEC CD-ROM DRIVE:285/3.04>, removable, dma, iordy This is strange, because DMA enabled on wd[01] and acd0 doesn't seem to... err "work". I say this because I am down to ~2.5MB/s on each hard drive, a MB or so decrease; I also seem to be reading (bs=512k) from the CD uncooked device at the right speed (~2MB/s), but it takes up 40% of the CPU, which seems to be just PIO.
