this is probably not the most intelligent post in the world, but i'm preparing to install gentoo in a dualboot configuration alongside os x, and i had a few quick questions specific to my powerbook before i went ahead, so i could both know what i was in for and possibly save myself some trouble. i couldn't find clear or current answers to a number of these.

1. resizing an hfs+ partition: i've come across references to using parted to shrink an hfs+ partition to make room for linux partitions, but just as many references to this either not being possible or parted balking on the attempt to resize an hfs+ partition (i saw this last one right in this forum). so is this possible to do or not, since this would save me the effort of having to back up 18 gb of files without a dvd burner.

2. assuming i can shrink an hfs+ partition, does yaboot have issues with booting past a certain filespace? i've come across a couple references to yaboot having a 10gb limit on what it can boot, which doesn't seem to make sense to me based on the current sizes of hard drives, but i was unable to ascertain how recent these references were. every howto i've seen for installing linux alongside os x on a powerbook or ibook says to put the linux partition before the os x partition, and if this is necessary then it makes my first question pointless. does it matter which order the partitions are on the disk?

3. airport: i've seen airport listed in the kernel configuration, but does the airport driver support the "airport extreme" 802.11g cards?

4. graphics: this is a new aluminum g4 powerbook with an ATI Mobility Radeon 9700. i've seen references to some powerbook graphics chipsets having driver issues with the kernel, is this one of them? also, does anyone know if the DVI/S-video ports work fine with gentoo for doing multiple displays?

5. gigabit ethernet: i played around with the kde/gnome livecd from 2004.0, and it failed to recognize the gigabit ethernet as present in any form. is this an issue with the livecd or a hardware compatibility issue? (granted, i wasn't sure what module i would want to modprobe to try to find it).

if there are any post install fixes for any problems these things have, i'm comfortable with whatever. i'm not a newbie to linux, just a recent transplant from x86.

thanks for any help.

1. There are also other people with the same question. Maybe this posts are 'helpful' for you:

https://forums.gentoo.org/viewtopic.php?t=38721&highlight=resize+partition+ppc

I installed Gentoo the day I got my Powerbook - so I simply wiped out the whole MacOS partition and then I created some new ones. But I don't think is will do it for you...

2. My configuration:
Code:
/dev/hda1 31.5 kb - partition map
/dev/hda2 800.00 kb - NewWorld bootblock
/dev/hda3 127.2 M - free space
/dev/hda4 18.5 GB - HFS
/dev/hda5 512 MB - swap
/dev/hda6 36.8 GB - Linux native (ext3)


So my linux partition is AFTER the OS X partition and it really works... ;-) No problems with yaboot so far! I hope this answers your question

3. I think Airport is supported, but not the Airport Extreme chipset. I don't know if anyone is currently doing some reverse-engineering on this Broadcomm chipset. But, thisthread is some kind of funny:

Also look at this thread (what works / what not):

https://forums.gentoo.org/viewtopic.php?t=162622

4. hehe... look at https://forums.gentoo.org/viewtopic.php?t=162622 again... ;-)

No DRI / OpenGL for Radeon 9700 and no working DVI/S-video output! So keep your MacOSX partition to watch DVDs!

5. I was using the minimal PPC LiveCD and I had no problems with the network card - use the SUNGEM drivers!

Overall I have to say (beside the Video issues): Gentoo Linux on my Powerbook is so sexy and great! If you have further questions first search the forums and then ask again!
