I understand the OBP program looks for the boot-device, loads the bootblk (located on physical disk sectors 1 through 15). Then the secondary boot program, /platform/`arch -k`/ufsboot is run. This program loads the kernel core image files (genunix and unix).
So how does it uses the ufsboot and... (1 Reply)

FDISK(8) BSD System Manager's Manual FDISK(8)
NAME
acorn-fdisk -- partition editor for Acorn/RISC OS machines
SYNOPSIS
acorn-fdisk -h | --help | -v | --version
acorn-fdisk [-t scheme | --type scheme] -l | --list [device ...]
acorn-fdisk [-t scheme | --type scheme] -s | --size partition
acorn-fdisk [-t scheme | --type scheme] [device]
DESCRIPTION
The acorn-fdisk utility allows one to display or interactively edit partition tables for Acorn/RISC OS machines in various formats. Using
the PC/BIOS format, standard IBM PC (i386) partition tables can also be accessed. When no optional device is given, it defaults to /dev/hda
or /dev/sda.
The options are as follows:
-h | --help Display a short usage and exit immediately.
-l | --list Display the partition table(s) of all devices.
-s | --size Display the size of partition.
-t | --type Select the partitioning scheme to use. Valid schemes are:
EESOX Eesox SCSI on the Acorn machines.
ICSIDEFS ICS IDE.
Filecore/Linux Linux on Filecore. This uses the non-ADFS descriptor to point to the start of the disc to be partitioned. The
first two sectors contain a partition table to identify the Linux partitions contained within.
PC/BIOS PC/BIOS partitioning scheme. This consists of a partition table in the first sector of the disk which contains
both CHS and LBA values for the partitions. There can be up to four entries in the primary partition table.
One of these can be an extended partition containing up to four extra partitions.
PowerTec PowerTec SCSI on the Acorn machines.
Filecore/RISCiX RiscIX on Filecore.
-v | --version
Display the version of acorn-fdisk and exit immediately.
If neither -l | --list or -s | --size are given, the partition table of the given device will be edited interactively.
EXAMPLES
Display the default device's partition table on a PC:
acorn-fdisk --type PC/BIOS -l
Display the PC partition table of /dev/sda:
acorn-fdisk --type PC/BIOS --list /dev/sda
Display the size in blocks of the partition /dev/sda1:
acorn-fdisk --type PC/BIOS --size /dev/sda1
Edit the MBR partition table interactively:
acorn-fdisk --type PC/BIOS
Display the partition table of an MBR backed up to a file:
acorn-fdisk -t PC/BIOS -l mbrdump.bin
Display the size of the first partition on a device where the MBR would be restored from the backup file mbrdump.bin:
acorn-fdisk -t PC/BIOS -s mbrdump.bin1
