|
|
.Os
|
|
.Sh NAME
|
|
.Nm installboot
|
|
.Nd install a bootstrap on an FFS filesystem partition
|
|
.Sh SYNOPSIS
|
|
.Nm /usr/mdec/installboot
|
|
.Op Fl Ntuv
|
|
.Ar device
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
prepares the
|
|
.Pq physically
|
|
first partition on a device for boot-strapping from the TOS-ROM. The
|
|
bootstrap is written into the bootblock area on the partition, right
|
|
in front of the disk pack label, and hence limited in size to
|
|
LABELOFFSET bytes. A disk pack label should be created
|
|
.Po
|
|
see
|
|
.Xr disklabel 8
|
|
.Pc
|
|
before installing the bootstrap.
|
|
.Pp
|
|
The bootstrap is split into two parts: a small first-stage program
|
|
that resides in the
|
|
.Pq physically
|
|
first 512 bytes on the device
|
|
.Pq as specified by Atari Corp. ,
|
|
and a second-stage program that immediately follows the first-stage
|
|
program. The first-stage program is loaded into memory by the ROM.
|
|
After receiving control, it loads the second-stage program and the
|
|
disk label. The second-stage boot program uses the stand-alone
|
|
filesystem code in
|
|
.Dq libsa.a
|
|
to load the kernel from the root-filesystem on the device. The
|
|
prototype code for the first-stage boot program can be found in
|
|
.Pa /usr/mdec/fdboot
|
|
.Pq floppy disk code ,
|
|
.Pa /usr/mdec/sdboot
|
|
.Pq SCSI disk code
|
|
and
|
|
.Pa /usr/mdec/wdboot
|
|
.Pq IDE disk code .
|
|
The second-stage boot program is stored in
|
|
.Pa /usr/mdec/bootxx .
|
|
.Pp
|
|
For backwards compatibility with the vendor specific AHDI disk
|
|
label, a\ special first-stage boot program is provided in
|
|
.Pa /usr/mdec/xxboot.ahdi .
|
|
Together with the general second-stage boot program, it is installed
|
|
in the AHDI partition where the
|
|
.Nx
|
|
disk label lives. Furthermore,
|
|
the AHDI specifications require an additional bootstrap, which is
|
|
written into the AHDI root sector
|
|
.Pq disk block zero .
|
|
The prototype code for this AHDI compliant bootstrap can be found in
|
|
.Pa /usr/mdec/sdb00t.ahdi
|
|
and
|
|
.Pa /usr/mdec/wdb00t.ahdi .
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width flag
|
|
.It Fl N
|
|
Do not actually write anything on the disk.
|
|
.It Fl t
|
|
Number of tracks per cylinder (IDE disk).
|
|
.It Fl u
|
|
Number of sectors per track (IDE disk).
|
|
.It Fl v
|
|
Verbose mode.
|
|
.El
|
|
.Pp
|
|
The arguments are:
|
|
.Bl -tag -width device
|
|
.It Ar device
|
|
The name of the device on which the bootstrap is to be installed.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following command will install the first-stage and second-stage
|
|
boot programs in the bootblock area on
|
|
.Dq sd0c :
|
|
.Bd -literal -offset indent
|
|
installboot sd0

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command first appeared in
|
|
.Nx 1.1
|
|
.Sh BUGS
|
|
.Nm
|
|
knows too much about kernel internal details, forcing it to
|
|
check the running kernel's release and revision.
|
|
.Pp
|
|
Because neither the floppy disk driver nor
|
|
.Xr disklabel 8
|
|
are capable of creating a disk pack label on a floppy disk,
|
|
.Nm
|
|
has to create a\ fictitious label, that is not used by the kernel.
|
|
.Pp
|
|
Except for installation of the bootcode on floppy,
|
|
.Nm
|
|
automatically sets the boot preference in NVRAM to
|
|
.Nx .
