Undocumented:

/IW       - Bypasses needing to read the License screen. Needs to be upper
            case when run within Windows.
/IP       - Ignores Plug and Play.
/IR       - By passes the checkin into the system CMOS. Useful for some
            combinations of motherboard and Award BIOS ver 4.50 P.
/D        - If you do not want Setup to use your existing Windows
            configuration (such as your current Win.ini and System.ini
            files), use this switch.
/N        - Allows setup to run without a mouse.

Documented:

filename  - Runs the particular INF file.
/ID       - Ignores the DIsk Space check.
/IS       - Ignores the routine System check.
/IQ       - Skips the test for cross-linked files.
/IM       - Skips the memory check.
/IN       - Runs setup without the Network Setup Module.
/NTLDR    - Eliminates check for previous operating system.
/P        - Detection Switch Option String.
          - Using a /P allows you to use an additional switch for viewing and
            setting some detection parameters.
            You can separate them with a semicolon (;).
            For example /P g=3;i;p.
g=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.
            The default is 0.
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.
i         - This switch tells Setup not to report the existence of a Plug
            and Play BIOS. It is useful on systems that have a Plug and Play
            BIOS that is not reported in Machine.inf.
p         - This switch enables performance logging. It writes performance
            timing information to the DETLOG.TXT file.The default is disabled.
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 graphical
            user interface (GUI). The default is disabled.

1. Create a new folder with the name: 'Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}'.
2. You can rename the "Control Panel" portion of the folder to whatever you like.
3. You may find it useful to place this 'hard-link' into the 'start-menu' for quick access.
4. To place in start-menu, right click 'Start' and choose 'open'. Cut and Paste the link.

1. Create a template file with attributes like favorite font and size.
2. Copy template to the \Windows\ShellNew directory. This is a 'hidden folder' so check permissions.
3. Open the registry editor [regedit.exe].
4. [HKEY_CLASSES_ROOT] - Find the extention of your template.
5. Make a new 'key' named 'ShellNew'.
6. Make a new string value within ShellNew called 'FileName'.
7. Set the FileName string value equal to the template filename (template.ext).

1. The control panels are in the \Windows directory with the extension of CPL (*.cpl).
2. There are two ways of accessing them. One is double-clicking them in Windows 98.
3. In Windows 95, use the run menu or command prompt 'rundll32.exe shell32.dll,Control_RunDLL c:\windows\system\filename.cpl'.

1. Open the registry editor [regedit.exe].
2. [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion].
3. Edit 'RegisteredOrganization' and 'RegisteredOwner'.

1. Install printer again under a new name.
2. Remember that the drivers are already installed so don't choose 'have disk'.
3. Save the alternate settings and choose this printer when desired.

1. Change the file attributes of SYSTEM.DAT and USER.DAT to 'not-system, not-hidden, and not-read-only' with the command 'attrib -s -h -r filename.ext'.
2. Copy SYSTEM.DAO and USER.DAO to SYSTEM.DAT and USER.DAT respectively. You will be over-writing the corrupt registry files.
3. Change the file attributes back to the original attributes of 'system, hidden, and read-only' with the command 'attrib +s +h +r filename.ext'.
4. [CTRL+ALT+DEL] - Restart the computer and the registry settings will be restored.

• The command line is: 'rundll32.exe rnaui.dll,RnaDial My Connection'.
• Make sure the name of the connection is verbatim with spaces and upper-case naming conventions used for the connection name.

1. Open the registry editor [regedit.exe].
2. [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\0000].
3. MaxMTU = 576
4. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP
5. DefaultReWindow = 8196
6. DefaultTTL = 64

You can use the MS-DOS ping.exe utility to determine a router's MTU.

I found the bbn.com or bbn network to break at 548 MTU. Meaning that the
MaxMTU above for a bbn network based machine should be set to 548 instead
of the 576 listed in the above tip.

You can also combine the MS-DOS utility traceroute.exe to ping different
routers on a path to find which router is breaking down the MTU as it
routes the packets to the next destination. Simply ping the router past
the router in question.
c:\>ping -f -l 548 www.bbn.com
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet.
Change 548 above to a higher number to determine the MTU of your network.
If the -l size is too large, you will receive the following:

C:\>ping -f -l 1500 www.bbn.com

Pinging www.bbn.com [128.11.41.197] with 1500 bytes of data:

Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.

The above results mean that you tried to ping www.bbn.com with a
TCP packet size of 1500 4 times. Each result returned a message
'Packet needs to be fragmented but DF set', the reason for this
result is because the -f switch set a flag in the TCP packet
instructing the packet routers not to fragment the packet. The
ping utility therefore returns a message stating that the packet
needed to be fragmented but since the 'Don't Frament' flag in the
packet was 1 or true, a router on the route to www.bbn.com refused
to relay your ping request. The router wanted to split the packet
into a size setup by the router engineers. This packet spliting
can lower bandwidth when taking into consideration the time it
takes to split the packet, send the 1st packet on the route while
buffering the other half, then send the 2nd packet. Besides the
time taken for the packet to be split, each packet had to wait its
turn to be transmitted while avoiding data collision. Don't forget
the packets must be re-assembled once they reach your machine.
