Speeding the Boot: SpeedyBoot

On many HP Integrity Servers and HP 9000 Systems, a ﬁrmware based

feature called SpeedyBoot allows you to bypass some of the boot-time

system tests in order to boot your system more quickly.

NOTE HP recommends that all self tests be performed, but recognizes the need

to have your system available as quickly as possible.

If you are conﬁdent that your system hardware is functioning properly,

you may choose to skip certain boot-time system tests in favor of having

your system boot up more quickly.

The SpeedyBoot features of your system allow you to specify which tests

to perform (or skip) and whether to do this only for the next boot or for

the next and all subsequent boots. There are several ways to deﬁne

which tests are performed. Which you use depends on:

• whether your system is running or not when you conﬁgure

SpeedyBoot settings

• whether your system is an HP Integrity Server or an HP 9000

System

• whether you want to conﬁgure the SpeedyBoot settings for only the

next boot or for all subsequent boots as well

• which release of HP-UX you are running (if you conﬁgure it using the

setboot command)

SpeedyBoot is achieved by reducing the number of ﬁrmware tests that

are performed at boot time. You specify which tests are performed. The

tests include:

✓ early CPU tests

✓ late CPU tests

✓ memory initialization (HP Integrity Servers only)

1. SpeedyBoot on HP 9000 Systems is supported only on systems

with ﬁrmware that supports the Boot Console Handler (BCH).

Some older platforms can be upgraded with new ﬁrmware that

supports SpeedyBoot.
