Wyse Technology WintermTM 9000 manual Write Filter Control Dialog Box

30

Start Run Open Command Line:

·wtflush.exe with no arguments - Brings up the Write Filter Control dialog box (Figure 12). This dialog box also may be accessed through the Start Programs menu or via the Administrative Tools selection in the Control Panel. See the following description of the dialog box.

·wtflush.exe \f - Flushes the cache and disables the write filter until the next boot. The write filter status icon is red.

·wtflush.exe \d - Flushes the cache and disables the write filter; the write filter stays disabled after the boot and must be enabled manually either through the dialog box or through the command line. The write filter status icon stays red while disabled.

·wtflush.exe \e - Write filter enabled after the next boot. After enabling the write filter you must reboot. You do not need to flush the cache first since the write filter is currently disabled. The write filter status icon is green when the write filter is enabled.

Note

Flush and disable (\f and \d arguments) open and automatically close a DOS command window during the process. However, the flush could take up to several minutes to complete after the window closes. Because the DOS window does not stay open long enough to view the results, you should open the Write Filter Control dialog box to determine if flushing has completed.

Note

The write filter status icon on the task bar system tray turns red immediately when the cache flush operation is started, although the flush action may take up to several minutes to complete.

Caution

Do not attempt to flush the cache while the cache is currently being flushed.

If you open a MS-DOS Prompt window (by entering command in the Run dialog), append “.exe” to the wtflush command: wtflush.exe, wtflush.exe \f, wtflush.exe \d, and wtflush.exe \e.
