I used hdparm -d1 to turn it on for the drives and that boosts to 41Mbs on the
drives, but the pdc still shows the following:
PDC20265 Chipset.
------------------------------- General Status ---------------------------------
Burst Mode : enabled
Host Mode : Normal
Bus Clocking : 33 PCI Internal
IO pad select : 10 mA
Status Polling Period : 0
Interrupt Check Status Polling Delay : 0
--------------- Primary Channel ---------------- Secondary Channel -------------
enabled enabled
66 Clocking disabled disabled
Mode PCI Mode PCI
FIFO Empty FIFO Empty
--------------- drive0 --------- drive1 -------- drive0 ---------- drive1 ------
DMA enabled: no no no no
DMA Mode: NOTSET NOTSET NOTSET NOTSET
PIO Mode: NOTSET NOTSET NOTSET NOTSET
...
I also have the kernel config you mentioned ... also even if the hdparm works,
having auto-activation on boot is really the ideal.
