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. - 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:
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.
Valid Detection Switches:
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=
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=
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=
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=
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=
detection modules, whereis 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=
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 perfor m 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 vx=
- This switch excludes the listed resources from detection, whereis 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)
