In tip 2038, I described the Safe-mode boot features in Windows 2000, that you activate by pressing F8 during boot.

In tip 0515, I described the switches that are available in c:boot.ini.

Here are additional Safe-mode switches:

Mode: Safe ModeSwitch: /SAFEBOOT:MINIMAL /SOS /BOOTLOG /NOGUIBOOTMode: Safe Mode with NetworkingSwitch: /SAFEBOOT:NETWORK /SOS /BOOTLOG /NOGUIBOOTMode: Safe Mode with Command PromptSwitch: /SAFEBOOT:MINIMAL(ALTERNATESHELL) /SOS /BOOTLOG /NOGUIBOOTMode: Enable Boot LoggingSwitch: /BOOTLOGMode: Enable VGA ModeSwitch: /BASEVIDEOMode: Directory Services Restore Mode (Domain Controllers Only)Switch: /SAFEBOOT:DSREPAIR /SOSMode: Debugging ModeSwitch: /DEBUG

You can add any of these Safe-mode entries to your boot.ini, by append the switch to the appropriate Arc Path or you can automate a Safe-mode by replacing boot.ini with something similar to:

[boot loader]timeout=0default=multi(0)disk(0)rdisk(0)partition(1)WINNT[operating systems]multi(0)disk(0)rdisk(0)partition(1)WINNT="Microsoft Windows 2000 Server" /fastdetect /SAFEBOOT:MINIMAL(ALTERNATESHELL)

or you can have something like the following, to manually select:

[boot loader]timeout=10default=multi(0)disk(0)rdisk(0)partition(1)WINNT[operating systems]multi(0)disk(0)rdisk(0)partition(1)WINNT="Microsoft Windows 2000 Server" /fastdetectmulti(0)disk(0)rdisk(1)partition(1)WINNT="W2K Alt Srv" /fastdetectmulti(0)disk(0)rdisk(0)partition(1)WINNT="W2K Directory Services Restore" /fastdetect /SAFEBOOT:DSREPAIR /SOSC:CMDCONSBOOTSECT.DAT="Microsoft Windows 2000 Recovery Console" /cmdcons

NOTE: The /SOS /BOOTLOG and /NOGUIBOOT switches are not required. When you press F8, you do get them as listed above.
