 Posted: Mon Sep 29, 2014 7:53 am Post subject: Installing gentoo on a G4 desktop |
 |
|
I've just started installing gentoo onto a G4 desktop. At work we have about 20 of these and wanted to get some more up to date software running on them. They still have the original Mac OS on them. A colleague of mine has debian stable running on one, and i wanted to try out gentoo.
Haven't done much yet other than prepare the disk. Going to have a go at compiling the kernel on it today.
Any suggestions about kernel configs, what desktop to use etc. welcome.

Just a heads up, there is a known issue using radeon KMS, AGP and libata together. See this post.
If you encounter this problem, radeon.agpmode=0 kernel parameter or switching to the IDE driver might help.
About the kernel config, start with "make pmac32_defconfig" and adjust as needed. |

Thanks for that,
I've just compiled a kernel but can't get it to boot. There's different reports via google of getting yaboot to boot a kernel from an ext4 filesystem, some say they can and some say they can't.
Here's my partitioning i have a swap partition on hda3 and then / on hda4 which is ext4. So no seperate /boot partition.
I'm going to try creating a small ext2 partition for /boot
So going boot from the cd again, tar what i have done already up, repartiton with a small ext2 partition for /boot, and then untar back to the disks again. Just to see if that solves my issue.

So I've repartitioned and have gone through a number of kernel recompiles. Here's the screen that is currently displaying just after yaboot.

It's hangs here.
My thought processes are that:
This is the kernel starting to boot right?
So then it might be some form of video/display issue?

Is it just me or does yaboot work correctly only after re-ordering in mac-fdisk so that bootstrap is on partition number 2 , as in, it won't work if it's at number 5 or anything else ?

| I haven't had that problem with yaboot. For example I currently have a PowerMac G3 with the boot partition on partition 4, and the OS on partition 3, and it works just fine. I would recommend the ext2 filesystem for the boot partition, as I know that yaboot can read that filesystem. That's the way I do it on PPC Macs and its worked well for me. |

|
|
| I was just thinking, and if you're referring to the Apple_Bootstrap partition, and not the separate /boot partition, then no I haven't tried that on anything other than partition 2. I was thinking of the /boot partition when I wrote my last post. If you do want to move it, you might try manually configuring yaboot.conf if you haven't tried that already. |
