Installing on G5

[Roger Mason]

Hello,

I am attempting to install freebsd-9.0 on a PowerMac dual processor G5
(970).  I burned the "bootonly" image to a CD and booted it from open
firmware using:

boot cd:,\ppc\loader cd:0

The cd does not boot.  The last messages are:

(cd0:ata0:0:0:0): cddone: got error back
iichb0: I2C error

Then the fan accelerates until I turn off the machine.

If anyone can offer suggestions they will be most welcome.

Thanks,
Roger
