Hi, |
| 2 |
Sorry for a semi-cross post between the yaboot list and |
| 3 |
Gentoo-ppc-users. I'm hoping to get this worked out today. |
| 4 |
|
| 5 |
I had trouble a week ago getting a new Gentoo PPC install to boot |
| 6 |
on my Mac Mini so for kicks I tried Ubuntu which booted fine. I'd like |
| 7 |
to get back to running Gentoo and I'm wondering what information I |
| 8 |
should retain from my Ubuntu installation. The new Gentoo install is |
| 9 |
back on the Mac Mini and completely up to date, so if I can work out |
| 10 |
the booting issue I should be good to go. I have not emerge yaboot as |
| 11 |
of yet as I don't want to break Ubuntu until the last moment if |
| 12 |
possible. |
| 13 |
|
| 14 |
To boot do I need anything beyond the info contained in the Ubuntu |
| 15 |
yaboot.conf, the hard drive partitioning and fstab to get Gentoo |
| 16 |
working? That's should be enough to somehow construct things correctly |
| 17 |
in Gentoo, correct? |
| 18 |
|
| 19 |
Also, the Ubuntu install used an initrd. I presume this is because |
| 20 |
their one-size-fits-all approach probably requires drivers to boot a |
| 21 |
lot of different machines. Previously when I had this Mac Mini running |
| 22 |
Gentoo I didn't use one. I don't need to, correct? (Assuming I can |
| 23 |
find and build in the right drivers?) Is there anything about yaboot |
| 24 |
vs grub that makes it prefer an initrd? For now I used the Ubuntu |
| 25 |
.config for my Gentoo kernel and figured I'd trim it down later after |
| 26 |
I get the machine at least booting. |
| 27 |
|
| 28 |
Thanks, |
| 29 |
