ok, I've got a lot of linux experience under my belt, but none on PPC hardware.. I have a couple older Macs (actually several, only 2 that are new enough to be PPC though).
one is a Performa 6400/180, second is a 5200/180 (not positive on numbering here, maybe a 5400??).. its the one-piece unit, PPC, PCI slot, etc etc.. pretty much the 6400/180 in a all-in-one box.

Neither of these run the OS9 fast enough to be usefull for anything, and I'd like to try converting them over to linux (both are equipped with 10/100 PCI NICs).

My biggest question is, will Gentoo PPC run on these? about a year ago I started to play with putting linux on the 6400.. got as far as burning an ISO of Mandrake PPC.. the disc was bad however and wouldnt fully boot, and I never went any further at the time.

Thanks

I haven't personally tried to install on the Performa, but according to
http://penguinppc.org/projects/hw/pmac.shtml, the 6400 and 5400 can boot linux, while if you have a 5200, you cannot. These are both OldWorld machines, which means you'll want to use BootX instead of yaboot for booting.

I have linux running on a PowerMac 9500, which has a G3 300 MHz upgrade chip in it. It runs, but I haven't upgraded KDE in a long time. I think it is still at a 1.x level, and I have a 2.2 kernel on it. It runs some custom legacy software I wrote and am too lazy to move, along with the data, onto a newer computer. Part of that is because I've got a SCSI disk that I cannot attach directly to my Tibook. If you have a good amount of memory, you may be ok with Gentoo, if not a little sluggish.

There is an installation guide for Gentoo PPC as well as a PPC FAQ. Also check out the penguinppc web site and FAQ for more info.

PCI-based OldWorld Macs are good for linux. I have a 7300 with a G3/400 upgrade, and it runs Gentoo quite nicely. Installation was a bit of a challenge at first, as the latest LiveCD (at the time) couldn't find my hard drive, and BootX is not the most intuitive program in the world. Now that it's all in place, however, it runs like clockwork, and I have a nice dual-boot Gentoo/MacOS-9.1 system.

NuBus-based OldWorld Macs, which include the 5200, are not well supported. I haven't tried it myself (got rid of my old 5200), but some hackers have managed to get linux onto those older Macs.

I can't find it in the current installation docs, but the old Gentoo 1.4 installation docs include this blurb:

Quote:
To install from the build CD, you will need to have a PowerPC 603 or better processor on a PowerPC PCI based system or newer. Less than 128mb ram is possible but the build process could be very slow under those conditions and could die. At the time of writing Nubus machines are not officially supported, but it should be noted that developers succeeded in installing Gentoo on nubus machines (using cross compilation and distcc).

I was going to try yellowdog...but here is my ideas?

I have a 6400/180 stock system with os7.55 (as in 16meg & 1.6 gig hd).

Since upgrading it macwise doesnt appear to be cost effective (as compared to buying a
a system) (Per preference to go osX). I decied to linux-ize it.

I pretty much assum ram is needed no matter what....

I do plan to network this setup, using my linksys card (its version 1) and will work per friend who says
his (same card) worked --- Wireless pci card.

With YDL, I have to boot via mac, though it asks early on whether to exit to mac or go LINUX.
With Gentoo, can I direct boot? or will be it be the same story?

I was under the impression that BOOTX is my only, but been reading at it seems its possible though problematic to quik.

I would prefer to linux-ize the 6400 in total...but if I have to, bootx wont be an issue for me.
