<application>abootconf</application> is used to change the partition<indexterm><primary>partition
</primary></indexterm>
the alpha Linux boot loader <application>aboot</application>(8)
looks for its configuration file in. The configuration file is stored
in <filename>etc/aboot.conf</filename>(5)
relative to the root of the file system in this partition.
</para>
<para>
<application>abootconf</application> requires the boot device
(e.g. <filename>/dev/hdb</filename>, <filename>/dev/sda</filename>) and the
partition
to be used (e.g. 3). Thus if you want to boot from partition E: on your second
SCSI disk you would enter</para>
<para>
<command>
abootconf <parameter>/dev/sdb 5</parameter>
</command>
</para>
</refsect1>
<refsect1><title>NOTES</title>
<para>
<application>abootconf</application> is not needed if you are booting
your alpha system via <application>milo</application>.
</para>
<para>
For each disk one partition can be activated to contain the configuration
for <application>aboot</application>(8) which is located in
<filename>etc/aboot.conf</filename>(5).
The disk chosen to boot from is selected at
the SRM prompt as the second argument, e.g.
</para>
<para>
<command>
boot <parameter>dqa</parameter>
</command>
</para>
<para>
to boot from your first IDE hard disk. See the HP SRM-Manual and
<application>aboot</application>(8)
for details.
</para>
<para>
<application>aboot</application>(8) can load a kernel from an
arbitrary partition and can even use a different
root partition than the one <filename>etc/aboot.conf</filename>
belongs to. Hence you would usually
set up one <filename>etc/aboot.conf</filename> with all combinations and
would not require <application>abootconf</application> except for initial
set up. You can then
boot the requested
Linux kernel by giving the appropriate flags at the SRM prompt, e.g. to boot
the entry labeled 2 you would use
</para>
<para>
<command>
boot <parameter>dqa -fl "2"</parameter>
</command>
</para>
<para>
See the HP SRM manual and <filename>aboot.conf</filename>(5)
for details.
</para>
<para>
To show the current setting simply omit the last argument (i.e. the partition
number).
</para>
<para>
Note that you have to rerun <application>abootconf</application> if you updated
<application>aboot</application>(8).
</para>
<para>
Strictly speaking <application>abootconf</application> is not necessary as
you can specify the partition which <filename>etc/aboot.conf</filename>
resides on at the SRM-Prompt by prepending the partition number and a colon
in the flags-parameter, i.e. if <filename>etc/aboot.conf</filename>
resided on the fourth partition and you want to boot the entry labeled 2
you could also issue
</para>
<para>
<command>
boot <parameter>dqa -fl "4:2"</parameter>
</command>
</para>
<para>
at the SRM prompt.
</para>
<para>
Note that this applies to Linux only as <ProductName>VMS</ProductName>, <ProductName>Tru64</ProductName>, *BSD and
<ProductName>Windows NT</ProductName> each have their own secondary boot loader.
</para>
<para>
Also note that for initial hard disk setup <application>abootconf</application>
is no longer needed as <application>swriteboot</application>(8) contains the
entire functionality of <application>abootconf</application>.
