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.
