[Tomasz Buziak]

moja pyta ;) to ABIT BD7 II na i845E

bash-2.05b# /sbin/hdparm -d1 -u1 -c3 /dev/hda

/dev/hda:
 setting 32-bit IO_support flag to 3
 setting unmaskirq to 1 (on)
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 IO_support   =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  0 (off)


dmesg:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH4: IDE controller on PCI bus 00 dev f9
PCI: Device 00:1f.1 not available because of resource collisions
ICH4: (ide_setup_pci_device:) Could not enable device.
hda: ST380021A, ATA DISK drive


bash-2.05b# /sbin/hdparm -i /dev/hda
