Subject: [gentoo-ppc-user] New install - Unable to get my ppc Mac Mini to boot the root partition

1 Hi all,
2 I have a Mac Mini that I've used for the last couple of years. I
3 was trying to get it up to date but at some point it failed with a
4 message about the main root partition not being an ext2 filesystem. I
5 took the opportunity to rebuild the machine from scratch, at this
6 point twice, but I continue to get the same message. I'm trying to
7 determine if something about the machine is completely hosed and the
8 machine will never work again or if it's just some problem I'm having.
9
10 In these rebuiilds I went the direction of completely wiping the
11 hard drive and starting from scratch. I used mac-fdisk, hit 'i', had
12 only the Apple partition map, and then created the next 3 partitions
13 as per the install guide. The installs (both of them) went cleanly and
14 I didn't seem to have any problems running yabootconfig as far as I
15 can tell. No complaints from the software except for my typing a path
16 to the kernel incorrectly a couple of times. Once I got that right it
17 seemed to finish and created the yaboot.conf file below.
18
19 When I attempt to boot the system finds the kernel, does all the
20 early boot stuff, says it finds /dev/hda and /dev/hda, then it starts
21 the init stuff with the green '*' and [OK] on the right until it wants
22 to mount the root partition. At that point it tells me the partition
23 is wrong, not ext2, and quits.
24
25 I don't understand how the partition can be incorrect if it's good
26 enough to find the kernel to boot.
27
28 Can someone set me right on what I might be doing incorrectly here.
29 If the info below isn't enough let me know what you need.

32 Mark
