It currently +supports booting the kernel from an ext{2,3} filesystem and usually resides in +the volume header of a disk with a SGI disklabel. +.SH "USAGE" +.PP +<device> is the device name of the disk containing the volume header +\fBarcboot\fR should go into. To use \fBarcboot\fR you have to modify +the following PROM variables: +.P +\fIsetenv OSLoader arcboot\fR +.P +\fIsetenv SystemPartition scsi(0)disk(X)rdisk(0)partition(8)\fR +.P +\fIsetenv OSLoadPartition scsi(0)disk(Y)rdisk(0)partition(Z)\fR +.P +\fIsetenv OSLoadFilename label_or_filename +.P +(where "X" is the scsi ID of the disk \fBarcboot\fR resides on and "Y" and "Z" +are the scsi ID and partition number of the partition \fB/etc/arcboot.conf\fR +resides on). Note that \fB/etc/arcboot.conf\fR and the directory your kernels +are in (usually /boot/) have to be on the same partition. On boot +\fBarcboot\fR looks at the \fIOSLoadFilename\fR PROM variable and tries to find +a label with the same name in \fB/etc/arcboot.conf\fR. + +.SH "Configuration File" +An entry in \fB/etc/arcboot.conf\fR has the following format: +.P +label=<label> + image=<kernel> + append=<boot options> + +<label> is referenced by \fIOSLoadFilename\fR, <image> is the path to the +kernel(again relative to \fIOSLoadPartition\fR) and <boot options> are the +options appended to the kernel's command line. + +.SH "Example" +label=linux + image=/boot/vmlinux-2.4.17 + append="root=/dev/sda1 console=ttyS0" + +.SH "Notes" +arcboot only loads ELF kernels. It doesn't handle ECOFF kernels to keep arcboot +as small as possible and because ECOFF kernels on mips don't contain any symbol +information which makes debugging more difficult. + +.SH "Files" +.BR /etc/arcboot.conf +\fBarcboot\fR's configuration file +.P +.BR /usr/share/doc/arcboot/README +more details on howto setup arcboot +.PP +.SH "SEE ALSO" +.PP +dvhtool(1), elf2ecoff(8), tip22(8) +.SH "AUTHORS" +Arcboot is based on the arc bootloader for SGI Visual workstations written +by Ralf Bächle <ralf@gnu.org>.
