.Sh DESCRIPTION
|
|
.Sy 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,
|
|
and unless this fails, the system will resume multi-user operations.
|
|
.Pp
|
|
.Sy Cold starts.
|
|
The X68000/X68030 system boots from the device
|
|
which is determined by the configuration of
|
|
battery-backuped SRAM.
|
|
By default, the boot rom attempt to boot from
|
|
floppy disk drive (from 0 to 3) first,
|
|
and then attempt to boot from hard disk (SASI or SCSI).
|
|
On the
|
|
.Nx Ns Tn /x68k Ns ,
|
|
booting from partition A of SCSI disks (sd?a)
|
|
and 2HD floppy disks (fd?a, fd?c) is currently supported.
|
|
.Pp
|
|
First, the initial program loader of IOCS ROM or SCSI disk
|
|
(or equivalent) reads
|
|
.Pa boot
|
|
program at the top of the disk,
|
|
and then the boot program loads the
|
|
.Nx
|
|
kernel
|
|
.Pa /netbsd
|
|
which is in the same partition of the disk.
|
|
If you press
|
|
.Pa [SHIFT]
|
|
key when booting, the boot program enables you to change
|
|
boot flag
|
|
.Dv RB_SINGLE
|
|
with the
|
|
.Pa [SHIFT]
|
|
key, and to choose which kernel
|
|
to be used with arrow keys.
|
|
If the LED of
|
|
.Pa [HIRAGANA]
|
|
key is turned on, the boot program adds
|
|
.Dv RB_KDB
|
|
flag and tries to boot the system in debug mode; see
|
|
.Xr ddb 4
|
|
for details.
|
|
.Pp
|
|
Note for X68030+MC68030 systems:
|
|
Nothing special to be attended to; you can boot
|
|
.Nx
|
|
just like as
|
|
other operating systems such as Human68k and OS-9.
|
|
.Pp
|
|
Note for X68030/040turbo(68040 accelerator by BEEPs) systems:
|
|
.Nx
|
|
can boot under 040 mode.
|
|
It can also boot under 030 mode if you have MC68030 on the board.
|
|
.Pp
|
|
Note for X68000/Xellent30(68030 accelerator by TSR)+MC68030 systems:
|
|
In order to boot
|
|
.Nx ,
|
|
you must choose 030 mode by using
|
|
.Pa CH30.SYS ,
|
|
which must reside in the battery-backuped SRAM.
|
|
.Pp
|
|
Note for X68000/Jupiter-X(68040/060 accelerator by FTZ-net) systems:
|
|
The system must be in 040/060 processor mode.
