Additional
Information
Information about Safe Mode in Windows 95, Windows 98 and Windows Me
Safe Mode is
a diagnostic and troubleshooting mode of Windows. Safe Mode bypasses
the portion of the registry that loads protected mode device
drivers, and bypasses the Autoexec.bat and Config.sys files. Safe
Mode prevents all 32-bit (protected mode) disk drivers from being
loaded except the floppy driver.
You may want
to enable this setting if your computer does not start due to disk
peripheral input/output (I/O) problems. If you start your computer
in Safe Mode, all I/O uses 16-bit (real mode) drivers or the basic
input/output system (BIOS). Also, all disk drives that are
functional in protected mode only, such as CD and DVD drives, no
longer function in Windows.
Safe Mode
uses the original registry settings, System.ini, and
Win.ini files. This effectively bypasses the [Boot] and
[386Enh] sections of the System.ini file and disables all the
Windows protected mode devices listed in Device Manager. Also,
Windows Safe Mode does not run programs listed on the Load=
and Run= lines in the [Windows] section of the Win.ini file.
Safe Mode
uses a Standard VGA video driver and resizes the desktop to a
resolution of 640 x 480.
Safe
mode in Windows 2000 and XP
Windows XP
and Windows 2000 provide Safe Mode, a startup option that disables
startup programs and nonessential services to create an environment
useful for troubleshooting and diagnosing problems. In Safe Mode,
Windows starts a minimal set of drivers that the operating system
needs to function. Support for devices such as audio devices, most
USB devices, and IEEE 1394 devices is disabled to reduce the number
of variables that you need to consider when diagnosing the cause of
startup problems, Stop messages, or general system instability.
Logging on to the computer in Safe Mode does not update Last Known
Good Configuration information. Therefore, if you log on to your
computer in Safe Mode and then decide you want to try Last Known
Good Configuration, the option to do so is still available.
The following
registry key lists the driver and service groups enabled in safe
mode:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal
