.Dd April 3, 2002 .Dt INSTALLBOOT 8 .Os .Sh NAME .Nm installboot .Nd install disk bootstrap software . .Sh SYNOPSIS .Nm "" .Fl nv k -words .Op Fl b Ar bno .Ek k -words .Oo .Fl B .Sm off .Ar bno Op , Ar ... .Sm on .Oc .Ek .. k -words .Op Fl m Ar machine .Ek k -words .Op Fl o Ar options .Ek k -words .Op Fl t Ar fstype .Ek .Ar filesystem .Ar bootstrap .Nm "" .Fl c .Fl nv k -words .Op Fl m Ar machine .Ek k -words .Op Fl o Ar options .Ek k -words .Op Fl t Ar fstype .Ek .Ar filesystem . .Sh DESCRIPTION The .Nm utility installs and removes disk bootstrap software. .Nm can install .Ar bootstrap into .Ar filesystem , or disable an existing bootstrap in .Ar filesystem .
p (XXX: flesh out description of primary & secondary bootstrap, ...)
p The options recognized by .Nm are as follows: . l -tag -width "foobar" . t Fl b Ar bno Install .Ar bootstrap at block number .Ar bno instead of the default location for the machine and file system type. . t Fl c Clear (remove) any existing bootstrap instead of installing one. . t Fl m Ar machine Use .Ar machine as the target machine type. The default machine is determined from .Xr uname 3 and then .Ev MACHINE .
p The following machines are currently supported by .Nm "" : d -ragged -offset indent .Sy alpha , .Sy pmax , .Sy vax .Ed . . t Fl n Do not write to .Ar filesystem . . t Fl o Ar options Machine specific .Nm options, comma separated.
p Supported options are (with the machines for they are valid in brackets): . l -tag -offset indent -width alphasum . t Sy alphasum .Em [ alpha ] Recalculate and restore the Alpha checksum. This is the default for .Nx Ns Tn /alpha . . t Sy append .Em [ pmax , .Em vax ] Append .Ar bootstrap to the end of .Ar filesystem , which much be a regular file in this case. . t Sy sunsum .Em [ pmax , .Em vax ] Recalculate and restore the Sun and .Nx Ns Tn /sparc compatible checksum. .Em Note : No The existing .Nx Ns Tn /sparc disklabel should use no more than 4 partitions. .El . t Fl t Ar fstype Use .Ar fstype as the type of .Ar filesystem . The default operation is to attempt to auto-detect this setting. . t Fl v Verbose operation. .El . .Sh ENVIRONMENT .Nm uses the following environment variables: . l -tag -width "MACHINE" . t Ev MACHINE Default value for .Ar machine , overriding the result from .Xr uname 3 . . .El . .Sh FILES XXX . .Sh SEE ALSO .Xr uname 3 , .Xr boot 8 , .Xr disklabel 8 , .Xr init 8 . .Sh HISTORY The .Nm utility first appeared the depths of time (XXX). This version appeared in .Nx 1.6 . . .Sh BUGS XXX
