ultra dma redhat 7.3

[Mike Shilling]

im having some trouble enabling udma on my workstation.  ive got it working flawlessly on my server so I think i know what im doing :)   here is my setup:   Abit BD7II motherboard (hell if I can figure out what IDE chipset this has....the non-raid version of this board) seagate baracuda ataIV ultra100 60GB   here is what im seeing when I run hdparm:   [root@Godzilla ]# hdparm -d1 /dev/hda   /dev/hda:  setting using_dma to 1 (on)  HDIO_SET_DMA failed: Operation not permitted  using_dma    =  0 (off) and this is a message im seeing at boot:   Sep 17 10:16:34 godzilla kernel: Uniform Multi-Platform E-IDE driver Revision: 6.31 Sep 17 10:16:34 godzilla kernel: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx Sep 17 10:16:34 godzilla kernel: PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086, DID=24cb Sep 17 10:16:34 godzilla kernel: PCI: Device 00:1f.1 not available because of resource collisions Sep 17 10:16:34 godzilla kernel: PCI_IDE: (ide_setup_pci_device:) Could not enable device.
