The sparc bootblocks are split into two parts: a small first-stage program that is written into the superblock area in a partition .Po and hence is limited in size to SBSIZE - DEV_BSIZE bytes .Pc , and a second-stage program that resides in the filesystem proper. The first-stage program is loaded into memory by the PROM. After it receives control, it loads the second stage program from a set of filesystem block numbers that have been hard-coded into it by the .Nm installboot program. The second-stage boot program uses the device driver interface to the PROM and the stand-alone filesystem code in .Dq libsa.a to locate and load the kernel. The second-stage boot program and the prototype code for the first-stage bootprogram can be found in .Pa /usr/mdec/boot and .Pa /usr/mdec/bootxx respectively. The second-stage program commonly resides in the root directory as .Pa /boot . The utility .Pa /usr/mdec/binstall can be used to properly copy the second-stage bootprogram to its destination. This script takes care of post-processing that is required on non-Openboot machines. .Pp The options are as follows: .Bl -tag -width flag .It Fl a Ar karch Set the machine architecture. The argument .Ar karch can be one of .Dq sun4 , .Dq sun4c or .Dq sun4m . Sun 4c models with Openboot PROMs need the header to be present, while Sun 4 systems with the .Dq old monitor interface require the header to be stripped off. This is normally taken care of by .Nm installboot automatically, but it's useful when preparing a bootable filesystem for another system. .It Fl h Leave the a.out header on the installed .Ar bootxx program. This option has been superseded by the .Fl a Ar karch option. .It Fl n Do not actually write anything on the disk. .It Fl v Verbose mode. .El .Pp The arguments are: .Bl -tag -width bootxx .It Ar boot The name of the second-stage boot program in the file system where the first-stage boot program is to be installed. .It Ar bootxx The name of the prototype file for the first stage boot program. .It Ar device The name of the raw device in which the first-stage boot program is to be installed. This should correspond to the block device on which the file system containing .Ar boot is mounted. .El .Sh EXAMPLES The following command will install the first-stage bootblocks in the root filesystem .Pq assumed to be mounted on Dq sd0a using the file .Pa /boot as the second-level boot program: .Bd -literal -offset indent # installboot /boot /usr/mdec/bootxx /dev/rsd0a .Ed .Sh SEE ALSO .Xr disklabel 8 , .Xr init 8 .Sh HISTORY The .Nm installboot first appeared in .Nx 1.1 .
