Re: Installboot on Beige G3

Hi There

Just for the sake of completeness, I did get the same result from the
CF Card over IDE as I did on SCSI, I had to set the ide boot
configuration in the Openfirmware environment variables to get it to
work though.

Whilst the kernel doesn't load correctly with the same errors (FAILED
TO CLAIM PHYS and DEFAULT CLAIM) I swapped out the kernel on disk with
the one from the Installer CD, it booted for a second then I think had
issues that it couldn't find the CD. It went past too fast to be sure
but the kernel definitely loaded as I got the White text on a black
background for a second!

Given this I think I am going to be trying to build the kernel on the
hardware itself. I think the issue is the kernel is too big to load
and I am not sure where to go from here apart from this.

Thanks!
