An automatic 84consistency check of the file systems takes place, and unless this 85fails, the system comes up to multi-user operation. The proper way 86to shut the system down is with the 87.Xr shutdown 8 88command. 89.Pp 90If the system crashes, it will enter the kernel debugger, 91.Xr ddb 4 , 92if it is configured in the kernel. 93If the crash occurred during 94initialization and the debugger is not present or is exited, the 95kernel will halt the system. 96If the crash occurred during normal operation and the debugger 97is not present or is exited, the system will attempt a dump to the 98configured dump device (which will be automatically recovered with 99.Xr savecore 8 100during the next boot cycle), and after the dump is complete (successful 101or not) the kernel will attempt a reboot. 102.\" XXX .Pp 103.\" XXX .Ss Use of SRM Console 104.\" XXX .Pp 105.\" XXX console is used to bootstrap system 106.\" XXX .Pp 107.\" XXX boot flags, boot file 108.\" XXX .Pp 109.\" XXX console device names 110.\" XXX .Pp 111.\" XXX .Ss Console Behavior at Power-on, Halt, and Reboot 112.\" XXX .Pp 113.\" XXX auto_action variable 114.\" XXX .Pp 115.\" XXX .Ss System Bootstrapping Procedure 116.\" XXX .Pp 117.\" XXX boot environment 118.\" XXX .Pp 119.\" XXX primary/secondary vs. unified bootstrap 120.Sh FILES 121.Bl -tag -width /usr/mdec/bootxx_cd9660 -compact 122.It Pa /netbsd 123default system kernel 124.It Pa /usr/mdec/bootxx_cd9660 125primary bootstrap for 126.Dq cd9660 127(ISO 9660) file system 128.It Pa /usr/mdec/bootxx_ffs 129primary bootstrap for 130.Dq ffs 131file system 132(Berkeley Fast File System) 133.It Pa /usr/mdec/boot 134secondary bootstrap 135.It Pa /usr/mdec/netboot 136network bootstrap 137.It Pa /usr/mdec/ustarboot 138.Dq ustar 139disk and tape bootstrap 140.It Pa /boot 141secondary bootstrap (installed) 142.El 143.Sh SEE ALSO 144.Xr ddb 4 , 145.Xr installboot 8 , 146.Xr mkbootimage 8 , 147.Xr savecore 8 , 148.Xr setnetbootinfo 8 , 149.Xr shutdown 8 150.Rs 151.%T "Alpha Architecture Reference Manual Third Edition" 152.%Q "Alpha Architecture Committee" 153.%I "Digital Press" 154.%D 1998 155.Re 156.Sh BUGS 157The device names used by 158.Nx Ns Tn /alpha 159and the 160.Tn SRM Console 161often have no relation to each other. 162
