I want to use harddisk in WISP. But WIPS doesn't support DMA. If I try to
use DMA, I got:

# hdparm -d1 /dev/hdc

/dev/hdc:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)

Enabling DMA in kernel will not help.
WISP probably doesn't have compiled in kernel modules (drivers) for IDE
interfaces:

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PIIX4: IDE controller on PCI bus 00 dev 39
PIIX4: detected chipset, but driver not compiled in!
PIIX4: chipset revision 1
PIIX4: not 100% native mode: will probe irqs later

What can I do with this?
