I`d setup my box with Opensuse 11.2 (2.6.31.5-0.1-desktop) on a 32bit machine with a Mill. P650 LP PCI card. The card is working (X.Org X Server 1.6.5), but i thought it might be a good idea to install the latest bios. Before doing that, i tried to backup the bios by running
- Code: Select all
./pbioslin.bin -o mtxbios.lin
With a lot of kernel messages, the process terminated.
Help is much appreciated.
