Trouble installing on iBook G4

Hello PowerPC Debian users,


I just installed the latest stable Debian iso on my iBook G4, but the 
grub bootloader install failed during the installation.  When I boot, I 
get the grub prompt.  I've been trying to follow the instructions at 
posts like this one:

https://superuser.com/questions/1237684/how-to-boot-from-grub-shell

but the output ls gives me a ton of ieee devices and there's some weird 
glitch with GRUB where once I get a third way down the screen the text 
starts printing on top of existing text, so I can't see what I'm doing 
so I have to reboot and start over. Anyways, I'm guessing someone has 
probably had this same issue with this port before and that the powerpc 
port differs from x86 linux in this regard, so I thought I'd just ask 
the mailing list. Can anyone offer advice?
