by I am using kernel 2.2.16-3 (RH6.2)
with ide.2.2.16.all.20000825.patch.
Also, I'm using a Promise Ultra 100 controller.
Two IBM HD's are connected to the Ultra 100 (on
different ide ports). The drive on hde is an ATA-66
and the drive on hdg is an ATA-100. Both have correct
80 pin cables.
At boot, the Promise Ultra 100 bios configures the
drives correctly, i.e. channel 0 master (hde) into UDMA 4
and channel 1 master (hdg) into UDMA 5.
However, at linux boot, the ATA-66 drive comes up as
UDMA(33) whereas the ATA-100 drive comes up correctly as
UDMA(100). The hdparm -v command confirms these settings,
however, /proc/ide/pdc202xx shows both drives in UDMA4 (which
I don't believe, hdparm -t /dev/hde gives me same as I used
to get with my old PIIX4 UMDA 33 controller).
Any suggestions? I've attached boot messages etc below.
(obviously without the _nospam)
