Description of the Windows 95 and Windows 98 Setup SwitchesID: Q186111
|
This article describes switches you can use with the Setup program in Windows 95 and Windows 98. Note that some of the switches can be used with both Windows 95 and Windows 98, and some can be used only with Windows 98.
/m - This switch bypasses the playing of the Setup sound (.wav) files.
/na - This switch bypasses the program check and can use the following values:
0: default
1: No Windows-based program check, but MS-DOS-based program are
blocked.
2: No MS-DOS-based program check, Windows-based programs are
blocked.
3: No Windows-based or MS-DOS-based program check.
/nd - This switch ignores the presence of a Migration.dll file and is used
to force Windows 98 to overwrite newer files.
NOTE: Files that use the ",,,32" flag in the .inf file still
force Windows 98 Setup to keep the newer files.
/nf - Do not prompt to remove the floppy disk from the drive (for bootable CD-ROMs)
- Same as if there is a file named BOOTCD in the cabinet folder.<BR/>
- Same as if there is a "BootCD=1" line in the Msbatch.inf file.
/nh - This switch bypasses running the Hwinfo.exe program at 0 percent
files and RunOnce.
/nx - Do not check the version of Setupx that is running.
/ie - This switch bypasses the Windows 98 Startup Disk wizard screens. If
this switch is used, the Windows\Command\EBD folder is not created.
/iv - This switch bypasses displaying the Setup screens during an upgrade
within Windows.
/? - This switch provides a brief summary of the available Setup switches
and the correct command-line syntax to use them.
/c - This switch bypasses running SMARTDrive.
/d - This switch bypasses using your existing Windows configuration
(such as your current Win.ini and System.ini files).
/l - Use this switch if you have a Logitech mouse and want it enabled during Setup.
/n - This switch causes Setup to run without a mouse.
-s - Use this switch to use an alternate Setup.inf file.
/t:<dir> - This switch lets you specify where Setup copies its
temporary files. WARNING: Any existing files in this
folder are deleted.
/ig - Allows Setup to run on some older Gateway and Micron computers with an early BIOS.
/ih - This switch causes Setup to run ScanDisk in the foreground.
/im - Causes setup to ignore the conventional memory check.
/iq - If you use the /is switch to bypass ScanDisk or ScanDisk fails,
Setup checks your drive for cross-linked files. The /iq switch
prevents Setup from doing this.
/is - This switch causes Setup not to run ScanDisk.
/it - This switch bypasses checking for the presence of "dirty" or
"deadly" terminate-and-stay-resident programs (TSRs) that are known
to cause problems with Windows Setup.
/p - This switch causes Setup to pass string(s) directly to Detection
Manager (or Sysdetmg.dll). Setup does not interpret the content of
the string. The string can contain one or more detection options.
The /p switch is not used by itself. For more information on
the /p switch, please see the "/p Detection Switch Option String
Defined" section below.
a - This switch enables safe detection. It tells each detection module
to try safer detection methods. Safer detection methods may not
detect devices correctly.
The default during Setup is enabled. The default in other cases is
disabled.
Example: setup /p a
b - This switch enables Prompt Before mode. It prompts you before a
detection module is called so that you can step through each
detection module manually and decide if you want to skip it.
The default is disabled.
Example: setup /p b
c - This switch enables class detection. Class detection is a mechanism
for finding hints for a certain class of devices. For example, adapter
class detection looks for hints in the Config.sys and System.ini files
for CD-ROM drivers. If it does not find any, Setup displays a CD-ROM
check box asking if you have a CD-ROM drive.
The default during Setup is enabled. The default when you use the
Add New Hardware tool and docking/undocking detection is disabled.
Example: setup /p c
c- - Setup /p c- disables safe class detection. For example, this switch
tells Setup to always search on all network adapter cards, sound
cards, and CD-ROM drives.
Example: setup /p c-
d=<name> - This switch detects the listed detection modules only, where
<name> is a detection module name or a device class name.
Detection module names (such as DetectPIC and DetectAHA154x)
are found in the Msdet.inf file. Device class names can be
SCSIAdapter, net, and so on.
Example: setup /p d=detectpic
e - This switch enables Setup mode detection.
The default during Setup is enabled. The default in other cases is
disabled.
Example: setup /p e
f - This switch enables Clean Registry mode. It forces Detection to
clean the root branch of the registry before starting. This switch
is ignored when Setup is run in the Windows 95/98 graphical user
interface (GUI).
The default is disabled.
Example: setup /p f
g=<n> - This switch specifies the verbose level, where <n> is 0 to 3.
This switch controls how verbose the built-in progress bar is. At
maximum level (3), it shows all the resources of the detected
devices along with the progress bar. This switch can help to
identify which detection module causes a certain problem. For
example, if your mouse stops responding (hangs) during detection
but the system continues, there is no way to determine from the
log files which module hung the mouse. By turning this option on
and constantly moving the mouse during Setup, you can determine
which module is running when the mouse hangs.
The default is disabled (0).
Example: setup /p g=3
i - This switch tells Setup not to report the existence of a Plug and
Play BIOS. It is useful on computers that have a Plug and Play BIOS
that is not reported in the Machine.inf file
Example: setup /p i
j - This switch tells Setup to undo the results of the "Setup /p i"
switch. This switch should only be used after a computer that required
"Setup /p i" has updated its Plug and Play BIOS.
Example: setup /p j
NOTE: In Windows 98, the "/p j" switch is required to enable ACPI
support. Windows 98 maintains a BIOS list for ACPI computers, so as
BIOS manufacturers create a new valid ACPI BIOS, this is the mechanism
for causing Windows 98 to recognize it.
l=<n> - This switch specifies the logging level for Detlog.txt, where
<n> is 0 to 3.
The default is maximum logging (3).
Example: setup /p l=0
m - This switch enables Mini-windows mode.
This is enabled only when Setup is run under MS-DOS.
Example: setup /p m
n - This switch enables No Recovery mode. This option can be used to
turn off the Windows 95 Setup recovery mechanism (for example, this
switch prevents the creation of the Detcrash.log file).
The default is disabled.
Example: setup /p n
o=<traceoutput> - This switch specifies the trace output. The information
is written to the Tracelog.txt file in the current
directory.
This option is available only in the Debug version of
Sysdetmg.dll.
Example: setup /p o
p - This switch enables performance logging. It writes performance
timing information to the DETLOG.TXT file.
The default is disabled.
Example: setup /p p
r - This switch enables Recovery mode. It causes Detection to use the
Detcrash.log file, if found, for recovery. If this switch is not
enabled, Detection ignores and deletes Detcrash.log even if it is
found.
This switch is used if Safe Recovery is selected during Setup,
otherwise it is not used.
Example: setup /p r
s=<name> - This switch skips the listed detection modules or classes of
detection modules, where <name> is a detection module name or a
device class name.
Detection module names (such as DetectPIC and DetectAHA154x)
are in the Msdet.inf file. Device class names are SCSIAdapter,
net, and so on.
Example: setup /p s=detectpic
t=<n> - This switch specifies the trace level, where <n> is 0 to 9.
The default is disabled (0).
This option is available only in the Debug version of
Sysdetmg.dll.
Example: setup /p t=9
v - This switch enables Verify Only mode. Detection has two stages:
1. Verify existing devices in the registry.
2. Detect new devices.
This switch tells Detection to perform only stage 1. This switch is
used by the PCMCIA Wizard to verify legacy devices in the registry.
The default is disabled.
Example: setup /p v
x=<res list> - This switch excludes the listed resources from detection,
where <res list> is one of four possibilities:
- io(xxx-yyy,xxx-yyy,...)
- mem(xxxxx-yyyyy,xxxxx-yyyyy,...)
- irq(x,y,z,...)
- dma(x,y,z,...)
This switch protects resources so that no detection
modules can access them.
Example: setup /p x=io(300-30f,240-24f) Additional query words: 98
