Booting

# reboot

If you got MacOS running again, See hfsboot part to get Open Firmware prompt.

When you got Open Firmware prompt, as already shown at the table, You may boot manually by

0 > boot hd:,ofwboot.elf hd12:

Number designates the partition number. It depends your partition setup. It usually starts (the number of MacOS partition) + 1.

boot (Open Firmware)

1. boot device
2. boot file
3. optional argument

1. boot device consists of
   

      boot-device:,boot-loader-file-name
   

   Note that colon(:) delimits device to the left, and comma(,) designates that followed name is the boot loader filename.

   Boot device name depends what OF recognizes, so that it varies machine to machine. 'devalias' command on OF may help you to find out the name to use.

   boot-loader-file-name is usually ofwboot.elf or ofwboot.xcf Simple mapping to rember is: use 'ofwboot.elf for OF 3 or later, 'ofwboot.xcf' for OF 1 or 2. But this is not necessary strict.

2. boot file depends what is written in the boot-device, say, CDROM etc. You have to know the name of file by other sources.

   Its default is netbsd, netbsd.gz of the booting device. So if the name falls into this category, you don't need to type in.

   If your boot device and the / root partition resides in different place, you may say

      root-partition-device:/kernel-name
   

   for the boot-file to position different root. ( kernel-name is usually netbsd and you may say just root-partition-device: if it name is netbsd.)
3. optional argument
   The option is:

      -s     single user mode boot
      -a     ask boot device
      exit   exit to OF after argument processed
   

Permanent setup in OF

Or you may set OF variable with the command:

0 > setenv boot-device hd:,ofwboot.elf

0 > reset-all    (You need to this to memorize set above)
.....
0 > boot
