I have hex edited the mikep5 kernel to point to /dev/sdb2 (the ext3 partition and root filesystem for my Archii build, based on TheStorm's image).
The error message includes a list of available partitions, the only one being my sd card which has only the kernel on it.
I am running Crunchbang as my primary computer (the host I built the archii build with) and can give any info needed.
Thank you so much for the community's support.
PS: I noticed this is pertaining to PPC architecture, but it's an installation issue I suppose, so I won't be offended if the topic needs to be moved.
