When the kernel takes over, +it initializes itself and proceeds to boot the system. An automatic +consistency check of the file systems takes place, and unless this +fails, the system comes up to multi-user operations. The proper way +to shut the system down is with the +.Xr shutdown 8 +command. +.Pp +If the system crashes, it will enter the kernel debugger, +.Xr ddb 8 +,if it is configured in the kernel. If the debugger is not present, +or the debugger is exited, the system will attempt a dump to the +configured dump device (which will be automatically recovered with +.Xr savecore 8 +during the next boot cycle). After the dump is complete (successful +or not), the system will attempt a reboot. +.Pp +On most mac68k machines with "soft-power" after the IIcx, the power +switch can be physically rotated and locked in the 'on' position. +The native OS can be configured to automatically start the +.Tn NetBSD +boot program. Additionally, the NetBSD boot program can be configured +to boot +.Tn NetBSD +without intervention. When a system is so configured, it can crash +or lose power and reboot back to a fully multi-user state without +any intervention. +.Pp +.Sy The boot application +The boot application runs in the native OS on the system. It has a +dialog where booting preferences may be changed and an option whereby +these options may be saved. The preferences are stored in the program +itself, not in a preferences folder--thus allowing two separate copies +of the program to be configured differently (e.g. to boot different +netbsd or netbsd.test, or to boot from two different drives). +.Pp +One option that may be specified is a boot to single-user mode. This +stops the boot process very early on and allows system maintenence. +If one wishes to provide some security at this phase of the boot, remove +the +.Ql secure +option from ttye0 in the +.Xr ttys 5 +file. +.Pp +Another useful option that may be specified is the "serial console" +option. This will allow a serial device (terminal or computer) to +act as a console for the system. This device must be configured to +use 9600 baud, eight bits, no parity, and one stop bit (9600-N81). +Either the printer port or the modem port (tty01 and tty00, +respectively) may be used for this. +.Pp +It is sometimes useful to boot a kernel that resides in a folder +in native OS rather than from the usual location in the +.Tn NetBSD +file system. A radio button is supplied for this purpose. Note that +some programs will not run properly if the kernel is not found as +.Ar /netbsd +within the +.Tn NetBSD +file system. +.Sh FILES +.Bl -tag -width /netbsd -compact +.It Pa /netbsd +system kernel +.El +.Sh SEE ALSO +.Xr ddb 8 +.Xr savecore 8 +.Xr shutdown 8 +.Xr ttys 5 -- cgit v1.2.3
