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 +.Sy Booting OpenBSD using the bootloader +.Pp +When a bootable +.Tn OpenBSD +partition is created by means of +.Xr installboot 8 +, the Atari BIOS will automatically start the OpenBSD bootloader. By default +it will load the kernel image +.Pa /bsd +and attempts to boot it into multi-user mode. This behaviour can be changed by +either keeping the +.Pa Alternate +or the +.Pa Right-Shift +key pressed during the boot. When +the +.Pa Alternate +key is pressed, the bootstrap is aborted, causing the BIOS +to continue scanning the disks for a bootable partition (this is compatible +with AHDI 3.0). Pressing the +.Pa Right-Shift +key during the boot, causes the boot loader to enter the interactive mode. +In interactive mode, the command line looks like: +.Bd -ragged -offset indent +.Pp +.Op Ar OS-type +.Op Ar boot-path +.Op Ar boot-options +.Ed +.Pp +Each component of the command can be ommitted in which case the defaults +indicated will be used. +.Bl -tag -width +.It OS-type: +.Bl -tag -compact -width ".OpenBSD (default)" +.It .OpenBSD (the default) +.It .linux +.It .asv +.It .tos +.El +.Pp +If something other than +.Pa .OpenBSD +is specified, control is returned to the BIOS with the boot preference set to +the selected type. Due to limitations of the BIOS however, the search for +bootblocks is continued rather than restarted. +.It boot-path +This gives you the opportunity to boot another kernel, say: +.Pa /bsd.old. +The default is +.Pa /bsd +.It boot-options +These options are a subset of the +.Xr loadbsd +options. +.Bl -tag -width flag -compact +.It Fl a +Boot into multi-user mode (the default) +.It Fl b +Ask for a root device +.It Fl d +Enter the kernel debugger +.El +.El +.Pp +.Sy Booting using the loadbsd program +.Pp +When you want (or have to) start OpenBSD from GEM, you have to use the +.Xr loadbsd +program that is supplied on the kernel-floppy.
