A HP e3000 (Series 900) system undergoes a self-test upon reset.:
After resetting and testing, the system either autoboots or initiates an
interactive boot sequence. Whether or not the system autoboots depends on how
the autoboot flag is set and the presence of an autoboot file. For information
on using the AUTOBOOT command, refer to
