.Tn sparc64-specific
system bootstrapping procedures
.Sh DESCRIPTION
.Ss Power fail and crash recovery
Normally, the system will reboot itself at power-up or after crashes.
An automatic consistency check of the file systems will be performed
(as described in
.Xr fsck 8 ) ,
and unless this fails, the system will resume multi-user operations.
.Ss Cold starts
System boot blocks are installed near the start of the boot disk
using the procedure described in
.Xr installboot 8 .
The boot program attempts to load the kernel from partition
.Dq a
of the boot device,
which must currently be an
.Dq sd
or
.Dq wd
disk.
.Pp
The
.Fl s
flag to the bootloader will bring the system up in single-user mode.
The
.Fl a
flag instructs the system to prompt for the location of the root filesystem
and the primary swap partition.
The
.Fl c
flag instructs the system to enter the
.Dq User Kernel Config
mode upon startup (see
.Xr boot_config 8 ).
Other flags are currently ignored.
.Pp
The UltraSPARC OpenFirmware will normally load the kernel from the device and
filename as instructed by the
.Dq boot-device
and
.Dq boot-file
variables.
If the
.Dq boot-file
variable is empty, the
.Ox
bootloader will look for a kernel named
.Dq bsd ,
unless a different filename has been specified in the boot command.
To reset this variable to its default, empty, value, type the following:
.Pp
.Em \ ok
set-default boot-file
.Ss Accessing the PROM during runtime
If the
.Xr sysctl 8
variable
.Ev ddb.console
is enabled, at any time you can break back to the ROM by pressing the
.Dq L1
and
.Dq a
keys at the same time (if the console is a serial port the same is
achieved by sending a
.Dq break ) .
If you do this accidentally you can continue whatever was in progress
by typing
.Dq go .
