# README.mipsboot Steve McIntyre <steve@einval.com> 2004/07/19
The mips/SGI boot support allows you to create a bootable CD which
will work with big-endian mips SGI machines, for example bootable
installation media.
The method used for this is the same as in genisovh, a tool to make
CDs bootable for Linux on SGI.
The SGI firmware reads the first 512-byte "sector" off a disk and
parses information from a volume descriptor header in that sector. The
information in question is the location (start sector) and length of
bootable kernel images; up to 15 are supported.
The firmware will load and execute kernels listed. (I'm not sure what
it will do if more than one kernel is listed - it may display a boot
menu).
To use the SGI boot support code in genisoimage, simply specify the kernel
file locations (relative to the CD root) as follows:
genisoimage ... -mips-boot <kernel file #1> \
...
-mips-boot <kernel file #n> \
-o mips.iso mips-files
