Hi all,... after searching what's wrong that I can't turn on the DMA after upgrade I notice this on the boot message when SuSE start... --- 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. --- So how do I fix this Unknown IDE controller (beside re-install)... I use intel 845BGV (i845G) motherboard... TIA... PS: I also notice although SuSE seems OK with the upgrade, it's left a lot of unpleasant garbage here and there. 1. my NIC still work, perfectly fine... but when I take a closer look, i found unknown blablabla as eth0.... I just delete it and re-add it.... 2. same things goes for my sound card... it's working fine, but yast said it's unkown.... 3. also happend to my tv-tuner card.... PS2: if there's a way to remove the ide-controller driver & re-add it....
