something about the nvram:

There is still more, but I'm tired of this.
2011-01-24: info about usb devices and stuff:
root@kg-g5# usbconfig ugen0.1: <OHCI root HUB Apple> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.1: <OHCI root HUB Apple> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen2.1: <OHCI root HUB NEC> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen3.1: <OHCI root HUB NEC> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen4.1: <EHCI root HUB NEC> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen3.2: <Hub in Apple Extended USB Keyboard Mitsumi Electric> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen3.3: <product 0x310b vendor 0x04b3> at usbus3, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON ugen3.4: <Apple Extended USB Keyboard Mitsumi Electric> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
That device at ugen3.3 is ? Devices on PATA and SATA bus:

ad0 is for OS X, ad1 for FreeBSD.
2011-01-23: It doesn't look like both CPUs are working. This is from dmesg:
root@kg-g5# dmesg | grep -i cpu cpu0: IBM PowerPC 970FX revision 3.0, 1413.86 MHz cpu0: Features dc000000<PPC32,PPC64,ALTIVEC,FPU,MMU> cpu0: HID0 511081<NAP,DPM,NHR,TBEN,ENATTN> ULE: setup cpu 0 cpulist0: <Open Firmware CPU Group> on nexus0 cpu0: <Open Firmware CPU> on cpulist0 pcr0: <PPC 970 Power Control Register> on cpu0 cpu1: <Open Firmware CPU> on cpulist0 pcr1: <PPC 970 Power Control Register> on cpu1 htpic0: Version 1.2, supports 4 CPUs and 120 irqs openpic0: Version 1.2, supports 4 CPUs and 120 irqs fcu0: Location: CPU A INTAKE type: 0 ID: 3 RPM: 1440 fcu0: Location: CPU A EXHAUST type: 0 ID: 4 RPM: 1472 fcu0: Location: CPU B INTAKE type: 0 ID: 5 RPM: 1440 fcu0: Location: CPU B EXHAUST type: 0 ID: 6 RPM: 1472
I don't see a "setup cpu 1" in there. And top -P doesn't report more than one cpu. Silly me, SMP isn't in GENERIC on PowerPC.
2011-01-23: I installed FreeBSD 9.0-current from the bsdinstall-powerpc-20110116 snapshot) on a second hard drive (ad1) in the machine. boot -v is still needed, or else FreeBSD doesn't see the hard drive after booting the kernel, and root mount fails. dmesg output: verbose. Some details:

and what else
2011-01-23: booting from CD drive. I just learned about set hw.ata.atapi_dma=0 that you can set from the boot loader prompt, and decided to re-test all my images on CD. Sure enough, all of them now works. The images tested were: FreeBSD 8.1-release (disc1), FreeBSD 8.2-RC1 (disc1), FreeBSD 9.0-2010118-SNAP (disc1), bsdinstall-powerpc-20110116.
2011-01-21: I tested the new bsdinstaller (using the snapshot bsdinstall-powerpc-20110116) on this machine. Use Command-Option-O-F to get into OpenFirmware, then do
boot cd:,\BOOT\LOADER.;1 cd:0
the kernel boots, but gets error messages from the cd drive (after detecting the keyboard, probably when trying to mount root) and thats it. Let's try with the same image on a usb memory stick. From Open Firmware:
devalias ud /ht/pci@2/usb@b/disk@2 boot ud:,\BOOT\LOADER.;1 ud:0
As expected, it fails when trying to mount root from cd9660:/dev/acd0. But the keyboard works, and I can tell it to mount from cd9660:/dev/da0 instead (I can see that the usb memory stick is listed as da0). And now it boots! I told it do give med the LiveCD, and got a login prompt, I set up the network with
ifconfig gem0 up dhclient gem0
Unfortunately, no dns, since /etc/ is read only, so I can't put /etc/resolv.conf there.
Then I did dmesg > /tmp/some-file.txt, and used scp to copy it to another machine, like this: scp /tmp/some-file.txt user@ip-address:/directory,
which gave me is useful. dmesg output: normal, verbose.
Oh, and you can use sysctl dev.fcu to reset the fan watchdog, so they will quiet down.
2011-01-15: I put the FreeBSD 9.0-20101118-SNAP image on another usb stick, and booted from that. It successfully booted to the main screen, and I selected Fixit, then "from usb", and it said "no usb devices found". Bugger. I re-tried with the FreeBSD 8.2-RC1 image, also using a usb memory stick, this also booted to the main screen, I selected Fixit, then live filesystem "from usb" and it said "no usb devices found"". Bugger.
2011-01-14: I tested a CD made from the FreeBSD 9.0-20101118-SNAP image found here, but the effect was the same: no working keyboard. It was actually "worse" than the 8.2-RC1 image, because it stopped / hung before the Country Selection dialog, with output like this:
uhub_reattach_port: port 1 reset failed, error=USB_ERROR_TIMEOUT uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port 4
it looks like all usb devices fails to attach (including keyboard and mouse). Other interesting output is this:
iichb0: I2C error fcu0: iicbus read failed fcu0: FCU initialized, RPM shift: 3 fcu0: 7 fans detected! iichb0: I2C error fcu0: iicbus read efailed fcu0: RPM Fan not available ID: 3
Alas, no success with that image either.
2011-01-13: I tried booting the FreeBSD 8.2-RC1 image (disc1) from a CD. Ok, it works, but when it gets to the Country Selection dialog, the keyboard doesn't work.
2011-01-13: Today, I tried the FreeBSD 8.1-release disc1 install CD again, with load sbp (press space after the kernel has loaded, then 'load sbp' then 'boot) when booting. Which gave me this:
fatal kernel trap: exception = 0x03 (data storage interrupt) virtual address = 0xd53000 srr0 = 0x5c3130 srr1 = 0x3032 lr = 0x5be960 curthread = 0x83fb50 pid = 0, comm = panic: data storage interrupt trap Uptime 1s
Ouch. So I tried a straight boot from the CD again (by holding down the Option (alt) key and selecting the CD from the boot menu. Use the eject key on the keyboard to open the optical drive). This time I noticed the following output from the boot messages:
atapci0: 0x10 bytes of rid 0x20 res 4 failed (0, 0xffffffff). atapci: <ServerWorks K2 SATA150 controller> at device 12.1 on pci6 pcib1: failed to reserver resource for atapci1 atapci1: 0x10 bytes of rid 0x20 res 4 failed (0, 0xffffffff). atapci1: unable to map interrupt device_attach: atapci1 attach returned 6
and the machine hangs. Next, I try to boot the machine from a usb memory stick. I generated the image like this:
root@kg-v2# dd if=/home/tingo/dl/bsd/fbsd/8.1/FreeBSD-8.1-RELEASE-powerpc-disc1.iso of=/dev/da4 bs=10240 conv=sync 34562+1 records in 34563+0 records out 353925120 bytes transferred in 190.081106 secs (1861969 bytes/sec)
It did not show up on the boot menu, so I used Command-Option-O-F to get into Open firmware. It then fiddled at lot with dev / ls and devalias in open firmware, to figure out an alias for the usb memory stick. Here it is (with the memory stick in the usb port on the front):
devalias ud /ht/pci@2/usb@b/disk@2
then i booted the machine with
boot ud:,\boot\loader ud:0
which worked. Unfortunately, at the Country Selection dialog, I found out that the keyboard wasn't working.
2011-01-10: booting a FreeBSD 8.1-release disc1 install CD by holding down "C" when (re)starting the machine works. But the cd drive (acd0) give timeouts, the machine hangs there and then the fans starts to spin up.
