Re: [K12OSN] Getting eMacs to boot.



I've never done this before and I could be completely wrong, but I'll
take a stab at helping...

The problem is that the Macs are PowerPC, not i386 based, so they need
to download a different set of software to boot up. The good news is
that you can store both images on the same server and serve up the right
one based on MAC addresses. Once they've loaded the image and booted,
they're just creating an XWindows session to the server, so they can run
the same software on the server.

That's the theory, anyway, I think. You'll need to create a PowerPC thin
client image and serve that to the Macs when they boot. Other people may
be able to give you more specific info, but at least that gives you
somewhere to start.
