- <para>
- <indexterm><primary>aboot.conf</primary></indexterm>
- <filename>aboot.conf</filename> contains a list of boot settings
- for <application>aboot</application>(8). Each boot setting
- has a unique number which can be supplied at the SRM-Prompt.
- <indexterm><primary>SRM</primary></indexterm>.
- </para>
- <para>
- <filename>aboot.conf</filename> must be in a directory called
- <filename>etc</filename> on the <emphasis>same partition</emphasis>
- as your kernels reside on unless you explicitly list the partitions
- for your kernels (see below for details). So if you create a separate
- boot partition (called <filename>/boot</filename>) then
- <filename>aboot.conf</filename> should reside in <filename>/boot/etc/</filename>.
- </para>
- <para>
- In the following example the kernels reside on a different partition (hda4)
- then <filename>/</filename> belongs to (hda5), while in the fifth
- line <filename>/boot</filename> is on the same partition (hda6) as
- <filename>/</filename>.
- Therefore <filename>aboot.conf</filename> can be located on any of the
- three partitions but <emphasis>always</emphasis> in a directory
- <filename>etc</filename> at the top level of the file system on that
- partition. You can change the partition to use with
- <application>abootconf</application>(8).

- <para>
- The first number is a unique identifier for each boot configuration.
- To boot a certain configuration at the SRM-Prompt you would issue
- </para>
- <para>
- <command>
- boot <parameter>dka0 -fl "0"</parameter>
- </command>
- </para>
- <para>
- where dka0 has to be replaced by your boot device and the boot configuration
- (0 in this case) can be replaced by any defined in
- <filename>etc/aboot.conf</filename>.
- </para>
- <para>
- After the colon the number of the partition the kernel resides on is given. 1
- corresponds to the BSD partition labeled A:, 2 to B: and so on.
- </para>
- <para>
- After the slash the name of the kernel to boot is given, including a possible
- path. If your kernel does not reside on a file system but is located directly
- after <application>aboot</application>(8) at the beginning of the hard disk
- you would omit the number, the slash and the kernel name.
- </para>
- <para>
- Next the name of the partition to mount as <filename>/</filename> is given.
- Other kernel parameters follow as required. As shown also an initrd can be
- specified.
- </para>
- <para>
- The contents of this file can be shown before booting if necessary by
- using the interactive
- mode of <application>aboot</application>(8) (booting with the flag "i")
- and then issuing "h" at the <application>aboot</application>-prompt.
