I use only yaboot,
Here are the output from dmesg, while rebooting (with yaboot) the new installed
kernel from the hard disk hde and following the output from cat /proc/pci after
starting the systm from the debian 3.0 installation-cd holding down the c-key.
hda is the original hard drive installed in the machine and connected to the
original onboard ide-controller, where hde, with yaboot on it, is the hard drive
connected to the ACARD-controller card, on hde linux should be installed;

Don?t wonder, that there?s no cd-drive listed here in the /proc/pci, I assume
this is because the cd-drive is hdi, but there?s no hdi in the linux systems
device list yet, I?ve made hdi later with mknode, to make it possible for linux
to get access to the cd-drive for reading the kernel and installing it on the
hard drive.
