ProLiant ML150 Server NOS - (English) Installation and Software Guide

Installing Microsoft Windows 2000 Server and Small Business Server 2000
Recovery option #2: Safe Mode Boot
This is activated by pressing the F8 key during the OS boot. It provides a minimal
configuration with required drivers and services. The safe mode boot provides three
options:
•
•
•
•
•
•
Standard safe mode boot – provides no network services or drivers.
Networking disabled – excludes network services and drivers.
Directory services restore mode – brings system up with directory services
disabled with the intent of recovering active directory. Safe mode boot is guided
by the registry key hklm\CurrentControlSet\Control\SafeBoot with the use of the
Minimal and Network subkeys. The IO Manager and Service Control Manager
look at the registry to load the driver and services. Such approach avoids loading
a problematic driver or service.
Command prompt – provides an alternate command shell CMD.EXE instead of
the explorer. This is dictated by the registry key:
hklm\system\CurrentControlSet\Control\SafeBoot\AlternateShell
There is a Safe-Mode boot loophole. Since NTLDR loads “Boot Load” drivers, these
drivers bypass the IO Manager's Safe Mode check.
Recovery option #3: Recovery Console (RC) Boot
The Recovery Console (RC) can be used when safe boot fails. You can enter RC
using one of the following:
Booting from Windows 2000 CD-ROM
Installing the RC boot on the system
It is recommended to install the RC immediately after installing Windows 2000.
Start RC Booting from Windows 2000 CD-ROM
If you have a need of booting the Windows 2000 recovery console but this feature is
not installed on the system, use the following procedure to boot the RC from the
Windows 2000 CD-ROM.
