Netboot Revisited
Vagrant got the common infrastructure ppc netboot set up, and we tested it on a G3 iMac in the Mac area. With a little coxing and head scratching we got it to find yaboot and yaboot.conf, but after that the process couldn't find any of the other boot files. I'll transcribe the boot trace as best I can here.
<in OpenFirmware> > boot enet:0,ubuntu-installer\feisty-ppc\yaboot CLIENT: 00039315657e 192.168.2.128 SERVER: 00163e6c369e 192.168.2.29 <and some other stuff that winked in before switching to...> <yaboot monitor> Transfer FILE: /boot.msg FTP ERROR response 1 File not foundWelcome to yaboot version 1.3.13 Enter "help" to get some basic usage information boot: <cr> Please wait, loading kernel...

Vagrant said he grabbed the boot files from the feisty-ppc distribution. That's a problem right there, since the initrd file there doesn't work for several reasons, and there are some simple pathname mods necessary in yaboot.conf. My mods are on the resident G3 tower station (in the MacBuild area) on the Desktop in a folder named ubuntu_ppc_netinstall, free for the taking. That doesn't address the issue of not finding the rest of the boot files. The solution to that is down the dhcp/tftp/boot-server path somewhere.

eMac Video Resolution
Feisty installs on an eMac just fine, but the Xorg configuration is inadequate. The default configuration results in no X display of any kind. The vertical refresh rate is wrong. Reconfiguring the xserver doesn't fix anything.

suggest another horz/vert rate modification, but also shows how to use programs gtf and read-edid to construct the appropriate Modelines for the supported display resolutions. That's the next thing to try.

Extracted form one of the links I mentioned yesterday, here are the lines that I insert into the Display section of xorg.conf to get the display to work.

Netboot Revisited
We used the netboot/install setup to do a complete install on another iMac today. Works well. The process still needs an automated clock setter early in the installation
