booting CD ?

[Proniewski]

Hi,

just a quick question : I burnt a CD with the iso disk image, it's bootable
on PC's, but not in Macs...As I want to install NetBSD for PPC on my G4, i
need a bootable CD. How can I do ? (I'm using toast)

thanx in advance,

pat

Put the files ofwboot.elf (and/or ofwboot.xcf) at the root level of the
CD. Also place an ungziped copy of the NetBSD Installation Kernel at the
root level and name it "netbsd".

Use the Command-Option-O-F keys to boot into OpenFirmWare. At the prompt
enter:

boot cd:ofwboot.elf

or

boot cd:ofwboot.xcf

If that doesn't work you can try:

boot cd:netbsd

One of the first two _should_ boot up the Installation Kernel from the CD
and allow you to install the system. I works on some systems, but not on
all systems. If anyone can add to this or explain the possible failures
it would certainly help.

thank you very much, but what a plague having to turn around things eatch
time...Some times I get sick having bought a big G4 and being stuck with
MacOS.

Actually I'd try this one first, since if the machine's version of OF
understands elf then you should be able to skip ofwboot altogether.
If this doesn't work then try ofwboot.xcf.

Of course I'm not currently booting at all so maybe I shouldn't talk.

Signature failed Preliminary Design Review.
Feasibility of a new signature is currently being evaluated.

Thanks for the pointer! I saw Bill mentioned in another posting that OF
3.1.1 doesn't play to well with ofwboot, but that's the version my system
has and it successfully booted (or more correctly loaded) ofwboot.elf,
ofwboot.xcf and netbsd. I suspect what he means is that ofwboot has
problems dealing with the filesystem and may not sucessfully find the
file to boot. This happens on my system so the advice to first try
booting with "boot cd:netbsd" is excellent advice.
