Hmm, this is strange. 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. Anyone else?
