Re: Plea for help from PowerMac Open Firmware gurus -- Testing newoldworld pmac miboot 2.6 floppies


I was busy with lots of "real life stuff", so I was away from debian-boot a 
while... I'm sorry for that ;-)

for the woody floppy there was a perl-script to set the command-line 
parameters. i'm not sure whether this script could be re-used so I've 
attached it, so you can have a look. 

Oh, and btw, I'm just installing my oldworld 4400/200 mac with d-i and the 
daily built 2.4-floppy images (with root.img and root-2.img) and it seems to 
work fine - right now. I'll keep you informed in another mail.
