4.5 Booting with Controlled Startup
Section 4.1.4 explains the site-independent startup command procedure,
SYS$SYSTEM:STARTUP.COM. By default, when your system boots, it
automatically executes STARTUP.COM to execute startup events. Under
special circumstances, you might want to control site-independent startup when
you boot the system. For example, you might want to perform one of the following
tasks:
Task For More Information
Boot with an alternate site-independent startup procedure Section 4.5.1
Boot with an alternate site-independent startup command
procedure by default
Section 4.5.2
Boot with minimum startup Section 4.5.3
Display startup procedure commands as they execute Section 4.5.4
Caution
Do not modify STARTUP.COM. The system requires this procedure
to correctly start up the system. For information about modifying
site-specific startup procedures to perform site-specific operations, see
Section 5.2.
4.5.1 Booting with an Alternate Site-Independent Startup Procedure
The default system startup procedure is SYS$SYSTEM:STARTUP.COM.
Compaq recommends you do not modify STARTUP.COM. However, in special
environments, you might want the system to perform special startup commands.
The conversational boot lets you specify that the system temporarily use an
alternate startup procedure.
