That happens when we reprogram the video backend to use something  
resembling a linear framebuffer. I have no idea why it apparently  
freaks out the firmware ( reboot and such are firmware calls ) or how  
to get around it. No need to power cycle though - there's a reset  
button hidden in a hole next to the power button.

The firmware tries to load IRIX - change 'unix' to 'boot', the path  
may be wrong as well.
Then, I don't know if the installer sets up an SGI volume header with  
loader and everything - I netbooted my O2 and installed by hand. In  
doubt look at the stuff in /usr/mdec, there's a tool ( I forgot the  
name but it should be obvious ) to manipulate SGI volume headers and  
to install files in there - we need our own boot loader, not the one  
IRIX uses.
Yes, that's way more complicated than necessary.
X11 won't be all that fast - we don't have sufficient docs about the  
rendering engine ( I got some hints but no results so far ). It does  
run in 24bit though, and with a shadow framebuffer it's kind of  
bearable.

I think you need to specify the loader there, or rather what file to  
load from the volume header. Should be 'boot'. The kernel name is in  
another variable, OSLoadFilename.

Probably.

Very likely.

I'm using this:
OSLoadPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(0)
OSLoader=boot
OSLoadFilename=netbsd
SystemPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(8)

to boot from disk 1.

have fun
Michael
