4 A. System Partitioning:
5 1. Only FDISK partitioning has been tested on the RS/6000.
6 However, yaboot does support mac partitions on a mac, so they should
7 work on an RS/6000 if you really want to go that route.
8 2. Extended FDISK partitions have not been tested and are not expected to
10 3. yaboot must be installed by itself in a bootable partition of type 0x41.
11 This partition must be less than 10MB.
13 Recommended partition configuration:
14 /dev/sda1 : PREP Boot. Type 0x41. Size = 800K
15 /dev/sda2 : Linux swap. Type 0x82. Size = 128 MB
16 /dev/sda3 : Linux native. Type 0x83.
18 B. Building & Installation:
19 1. See the partitioning section for notes & examples on how to configure
20 your system partitions when installing Linux.
21 2. Build yaboot by doing:
23 3. Make a yaboot.conf file in /etc/yaboot.conf
24 4. Install yaboot by doing (as root):
27 C. Configuration File (/etc/yaboot.conf):
28 1. See the yaboot.conf(5) man page for the full range of options.
29 2. Options tested on an RS/6000 include:
30 timeout = <time in tenths of a second>
31 default = <default label>
32 root= <device containing the root filesystem>
33 image = <path to vmlinux kernel file>
34 label = <short name for this image>
38 ## example /etc/yaboot.conf for RS/6000
39 ## Timeout value is in tenths of a second
42 install=/usr/local/lib/yaboot/yaboot
52 image=/boot/vmlinux.new
