I have a rather old machine acting as a home server. According to dmesg
it has a:
--
atapci0: <Intel PIIX WDMA2 controller> port
0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0
--
However, both hard disks attached are running in PIO mode.
--
ad0: 4103MB <ST34321A> [8894/15/63] at ata0-master BIOSPIO
ad2: 6194MB <IBM-DADA-26480> [13424/15/63] at ata1-master BIOSPIO
--
I tried running the following, but as you can see the end result is that
they are still running BIOSPIO.
--
(root|bone)/home/mrboo# atacontrol mode 0 WDMA2 WDMA2
Master = BIOSPIO
Slave = BIOSPIO
--
Any suggestions as to how I might enable some sort of DMA on these
drives? Since the machine is rather slow (133MHz) and it's currently
using polled IO I am sure it will likely benefit me, even if it isn't
quite UDMA :)
