.SH NAME
boot.conf \- kernel loader configuration file
.SH DESCRIPTION
The \fBboot.conf\fP file describes which kernels are included in the
kernel loader menu, including any kernel dependent configuration information.
The file has the following format:
.RS
.sp
.I block-description
{
.I block-contents
};
.sp
.RE
Empty lines or lines beginning with `#' are ignored.
.IP \fIblock-description\fP
describes what this block contains.  Valid block names are listed below.
.IP \fIblock-contents\fP
describes various options available within this block.
.PP
Valid block-descriptions are:
.IP \fBconfig\fP
specifies a configuration block.  It may contain \fBroot\fP.
Multiple \fBconfig\fP blocks are allowed, and are processed sequentially.
.IP \fBkernel\fP
specifies a linux kernel configuration block.  It may contain
\fBargs\fP, \fBflags\fP, \fBinitrd\fP, \fBname\fP, \fBpath\fP,
\fBramdisk\fP and \fBroot\fP.  Multiple \fBkernel\fP blocks are allowed.
.IP \fBriscos\fP
specifies a riscos configuration block.  It may only contain the
\fBname\fP argument.  Only one of these may be in a file.
.PP
Valid block-contents are (subject to above restrictions):
.IP \fBargs\fP
specifies the default arguments to appear on the kernels command line.
(Optional)
.IP \fBflags\fP
specifies various flags (READONLY). (Optional)
.IP \fBinitrd\fP
specifies the path to an initial ramdisk to be loaded by the kernel loader.
(Optional)
.IP \fBname\fP
specifies the name to appear in the loader menu.
.IP \fBpath\fP
specifies the path to the kernel.
.IP \fBramdisk\fP
specifies the size of the ramdisk in kB.  If this is not specified,
the default of zero is used. (Optional)
.IP \fBroot\fP
specifies the root device.
.PP
.SH EXAMPLES
This is an example of a multiple kernel configuration file.
