DESCRIPTION
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.
Cold starts
 On an NeXT, the boot procedure uses the boot ROM to load a boot program over the network using BOOTP and TFTP. The 
/usr/mdec directory contains a network boot program which should be made available via 
tftp(1). The network boot program will load 
netbsd from the NFS root as determined by the procedure described in 
diskless(8).
