SuSE 8.1 boot disk hangs

Hello all, I have a system which has been running SuSE 8.0 and would like to install 8.1. I have to install via the network, so I am trying to boot a system via the boot disks provided in SuSE 8.1. The system hangs at the point where the IDE subsystem is initialized. The last thing I see is: [...] VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci:00:07.1 VP_IDE: ATA-66/100 forced bit set (WARNING)!! ide0: BM-DMA at 0xc000-0xc007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xc008-0xc00f, BIOS settings: hdc:pio, hdd:pio Is this a known issue and is there a work-around?
