Hello,
I recently received a IMAC G3 (700Mhz, circa 2001) and want to run FreeBSD on it. I tried 8.0, 7.2 and on both, the install fails very early on with a fata kernel trap message.
I break into the OF prompt then type:
boot cd:,\boot\loader cd:0
It looks like it starts the loader ok and it looks like it does it's thing and starts the kernel but then after just a second or two, the kernel fails with the following messages:
fatal kernel trap:
exception = 0x4 (instruction storage trap)
virtual address = 0x5121c8
srr0 = 0x5121c8
.... and so on.
I found a suggestion about pausing in the loader and shutting off fireware (slot 14) using a set command. I tried doing that but it made no difference.
I tried with both 8.0, 7.2 (and a quick test with 6.2) but none of them worked.
Should FreeBSD install work on an IMAC G3 700Mhz or am I beating a dead horse?
I also tried updating the IMAC firmware to the latest (1.4.9) but it made no difference.
The IMAC does boot OSX just fine. It also booted a Linux install CD (YellowDog I think...). So, I'm pretty sure the HW is functioning properly...
I did boot the FreeBSD 8.0 install CD on my eMAC (1.42Ghz) and it started up into the installer without problem.

You should have:: >setenv boot-device cd:0
> mac-boot
for the loader.
I'm still using the 9.0 SNAPSHOT. I've had better luck with it.
There is the Howto posted by the PPC freebsd developers and another which I posted at the freebsd forums. Look for freebsd on the powermac g-series in other architectures. Follow the basic instructions.
Is it Openfirmware you are using or not?
If it isn't, then I think=- not sure- that open or net bsd would work on it.
Don't quote me on this as being exact.
