I've been using Gentoo AMD64 on my desktop for some time now. The other day I decided to give Linux a go on my old iBook G4 800Mhz 12" with AirPort Extreme card installed by Apple. I downloaded the PPC 2006.1 Minimal LiveCD (always installed Gentoo with the minimal CD).

WIRELESS PROBLEM: When I booted up, i saw init start loopback and then eth0, no eth1. When I try to force load the module "bcm43xx" (or something like that), it tells me something about fw (firmware) being not found etc. I guess the particular Broadcom chipset requires firmware to be first extracted and available on disk or something? But that's not the problem, I thought I could just plug in a good old CAT5 and emerge the tool "bcm43xx-fwcutter" to extract it later after I installed Gentoo.

WIRED PROBLEM: I plugin ethernet cable. "net-setup eth0" Nothing, Before I used net-setup and told it to use DHCP, it showed eth0 under the output for "ifconfig"; after I used "net-setup", onlly loopback shows. To get it to show in the "ifconfig" output again, I have to do /etc/init.d/net.eth0 restart.

"lspci" reveals that the ethernet onboard this ibook is some kind of Sun Gem chip. And it loads fine at startup. But it just sort of "seg faults" as soon as you try to manually set IP/mask AND/OR by DHCP.

IN CONCLUSION: I can't get Gentoo installed because
1) I cannot use wireless until I have portage
2) I cannot have portage until I have stage3
3) I cannot have stage3 because my ethernet doesn't #@$#@$ing work.

I know that the ethernet port is NOT borked. It works fine in OSX and Ubuntu LiveCD.
Please help, I want to use Gentoo and not these other distros :((((((((

Wireless won't work as you've noticed, since we couldn't distribute the firmware with the cd at the time the 2006.1 release was made. That may change in the future.

Last time I used the minimal cd on my iBook I did not have to do anything to get networking setup. The cd takes care of it all. Admittedly I did have the cable connected when I booted it. The cd should bring up the interface and request an ip from the dhcp server on your network. eth0 should show up in the output of ifconfig -a. You could try using ifconfig to assign an ip to the interface and try pinging some machines on your network.

Booting with the Ethernet cable plugged in does not work. I'm almost positive it's because the dhcpcd that came with the live CD is buggy.

I doubt that dhcpcd is the problem, but if the ubuntu cd works, just boot that and install gentoo from there. The process is the same, since the minimal cd doesn't contain stage files either.
