Apple's Open Firmware.
by James Lyons
As an addition to our work trying to get the 6600 PCI-E working with
PCI Passthrough, I've got a QuickSilver G4 and a couple of Geforce/
Quadro cards.
I've been working on some FCode Roms for them, and I'd like to test
them before I flash it to the EEProm, however I don't seem to have the
commands correct.
" agp/@10" open-dev to my-self
load hd:12,\ppc\4600.rom
800000 1 byte-load
That all returns ok, but the FCode doesn't seem to execute.
Also, I had to strip the PCI Header from the ROM to get the load
command to work.
Have a look at this ROM and see if the FCode starts at 0x40, looks
like it does to me?

Seems I wasn't using a crossover cable, I don't know why anyone would
make a yellow cable that wasn't crossover.
Anyway, now I have input via telnet, but I can't get the Mac to boot
to a OF telnet session?
I tried to set it via nvramrc, but that doesn't seem to work:
setenv auto-boot? false
nvedit
" enet:telnet,10.1.2.3" io
nvstore
setenv use-nvramrc? true
reset-all
Returns me to the OF prompt but no in telnet.
I seem to recall doing this on an Old World Mac many years ago, I need
to change the input-device and output-device to enet?
