I-243 Your computer locks up when you are using the drag-and-drop method to move files to your floppy drive. The only way out is a reboot. Try this registry entry to help solve the problem.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Control\GraphicsDrivers\

Add the following key under the GraphicsDrivers Key:

Key: DisableUSWC

When you add this key, you tell Windows NT not to use Uncache Speculative Write Combining on the video cards. No value is needed under the DisableUSWC key. Reboot the machine for this change to take effect.

I-244 Modifying the registry entries below lets you disable the Long File Names feature in Windows NT. Note this change doesn’t change any disk structures; it only affects the way Windows NT behaves from the time you make the change.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Control\FileSystem
Value Name: Win31FileSystem
Data Type: REG_DWORD
Value: 1

Reboot your system for these changes to take effect.

I-245 Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Control\FileSystem
Value Name: NtfsDisable8dot3NameCreation
Data Type: REG_DWORD
Value: 1

This change prohibits Windows NT from creating an 8.3 twin for the long filenames you create.

I-246 Problem: In a previous version of NT, you were notified by a message that NT saw your 16550N UART chip. For some reason, that notification has stopped and you wish to enable it again. This registry modification makes NT notify you when it recognizes the 16550N UART.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\Serial

Make sure the following values are present. If any are missing, add them.

Value Name: ForceFIFOEnable
Data Type: REG_DWORD
Value: 1

I-247 Value Name: LogFIFO
Data Type: REG_DWORD
Value: 1

I-248 Value Name: PermitShare
Data Type: REG_DWORD
Value: 1

I-249 Value Name: RxFIFO
Data Type: REG_DWORD
Value: 0x8

I-250 Value Name: TxFIFO
Data Type: REG_DWORD
Value: 0x1

Reboot the system for these changes to take effect. The event log now reports “While validating that COM1 was really a serial port, a FIFO was detected. The FIFO will be used.”

I-251 Problem: You want to change the registered owner or organization to something other than the one you used during the installation. Change one of these values.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\WindowsNT\CurrentVersion
Value Name: RegisteredOwner
Data Type: REG_SZ
Value: <registered owner>

I-252 Value Name: RegisteredOrganization
Data Type: REG_SZ
Value: <registered organization>

I-253 Problem: You want to have a program run every time Windows NT loads, but you don’t want to put it in the startup folder where people can tinker with it. This registry modification lets you set a program to execute every time Windows NT loads.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\Run

Add the following value under the Run key:

Value Name: <any name>
Data Type: REG_SZ
Value: <fully qualified path and name of the program you want to run>

I-254 If you want the program to run only one time, use this registry entry.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\RunOnce

Add the following value under the RunOnce key:

Value Name: <any name>
Data Type: REG_SZ
Value: fully qualified path and name of the program you want to run
