I've also a 845G board in my Fujitsu-Siemens box, but it does not correctly
detect the IDE controller:
<6>Uniform Multi-Platform E-IDE driver Revision: 6.31
<4>ide: Assuming 33MHz system bus speed for PIO modes; override with
<4>PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086,
<3>PCI: Device 00:1f.1 not available because of resource collisions
<4>PCI_IDE: chipset revision 1
<4>PCI_IDE: not 100%% native mode: will probe irqs later
<4> ide0: BM-DMA at 0x2800-0x2807, BIOS settings: hda:DMA, hdb:DMA
<4> ide1: BM-DMA at 0x2808-0x280f, BIOS settings: hdc:DMA, hdd:DMA
<4>hda: MAXTOR 6L080L4, ATA DISK drive
<4>hdb: MAXTOR 6L080L4, ATA DISK drive
<4>hdc: IDE-CD R/RW 24x12A, ATAPI CD/DVD-ROM drive
<4>hdd: LITEON DVD-ROM LTD163, ATAPI CD/DVD-ROM drive
With a stock 2.2.18 kernel dma could be enabled, but the SuSE kernel
refused to do. Maybe the chip is too new...
