Thanks for the info. |

OK - as a test I'm going a very different direction. As there is a |
22 |
prebuilt Ubuntu PowerPC version I've just written a CD and it boots |
23 |
fine. I'm right now in the process of letting it blow away my |
24 |
non-functional Gentoo install and install Ubuntu. If that boots then I |
25 |
can see what they did and redo Gentoo later with that knowledge. |
26 |
|
27 |
As for using Gentoo on this box I'm not sure it's really worth it any |
28 |
more. My main machines now are all x86_64 - as is probably true for |
29 |
most people - but fast ones - an i5-661, i7-920 and an i7-980x where I |
30 |
run 5 copies of Windows 7 at the same time in different VMWare jails. |
31 |
I found I wasn't updating this old Mac Mini because it was too slow |
32 |
and took too much of what I call 'Gentoo effort'. If I can find a |
33 |
prepackaged version of MythTV for this machine then likely I'd be |
34 |
better off just to run Ubuntu. I don't really need performance for a |
35 |
MythTV backend server. |

|
37 |
Anyway, I'll report back more when I know more. |
