+.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 NetBSD/X68k, 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 NetBSD 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 8
+for details.
+.Pp
+Note for X68030+MC68030 systems:
+Nothing special to be attended to; you can boot NetBSD just like as
+other operating systems such as Human68k and OS-9.
+.Pp
+Note for X68030/040turbo(68040 accelerator by BEEPs) systems:
+NetBSD 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 NetBSD, 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.
