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