(Intel D845GBVL - 845g chipset). I am running a fresh RedHat7.3 install and have tried the stock RH kernel, and I'm up to 2.4.19-pre9. I have a CD burner and DVD drive attached which operated with DMA on an older 845 mobo. If I run hdparm -d1 /dev/hd(a or c), I now get: HDIO_SET_DMA failed: Operation not permitted Here is a snippet from dmesg: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086, DID=24cb PCI: Device 00:1f.1 not available because of resource collisions PCI_IDE: (ide_setup_pci_device:) Could not enable device.

Aside from this glitch everything else seems to run fine. Could someone give my a hand? Am I missing something simple, is my bios borked, or do I need a patch to support the newer chipset?
