3900/3950HD/3950C (250-3580/86/87) Video Utilities Faxback Doc. # 2696 VGA SOFTWARE DRIVERS The system's support diskette contains several software drivers. They can provide improved resolution for the appropriate software application packages. The drivers are all located in their own directories on the support diskette names \VGA\LOTUS,\ \VGA\PCAD,\ \VGA\WORD, and so on. A file named README.DOC on your support diskette (under the sub-directory VGA) has instructions on how to install the drivers. You can view or print out the file and read those instructions before installing the drivers. THE SWITCHER UTILITY On your support diskette you can find a program named SWITCHER.COM (\VGA\CLUTILS\SWITCHER.COM). This is a program which can be used to configure your VGA display options. SWITCHER is a Terminate and Stay resident(TSR) program. This means that when it is loaded, it stays resident in your system memory. So, after you execute SWITCHER, the program loads into memory and remains resident until your system is shutdown or reset, and can be invoked by keystrokes from the keyboard. The following table describes the various functions performed by SWITCHER and the keyboard commands necessary to invoke these function. The key acts as a toggle switches, that means each keystroke scrolls through to the next state. Some of these options are only available in certain configurations. Toggle Contrast Enhancement ON/OFF Crtl-Shift-A Toggle Vertical Positioning Control Crtl-Shift-C Toggle LCD/CRT/Simulscan Crtl-Shift-D Toggle Expand mode ON/OFF Crtl-Shift-E RGB weighting Crtl-Shift-G Toggle Full Height Cursor ON/OFF Crtl-Shift-O Toggle Reverse Video ON/OFF Crtl-Shift-R Toggle Screen Power ON/OFF Crtl-Shift-S Toggle Suspend Mode ON/OFF Crtl-Shift-U THE VGACONF UTILITY On your support diskette you can find a program named VGACONF.EXE(\VGA\CLUTILS\VGACONF.EXE). This is another program which can also be used to configure your VGA display options. This can be done in either of two ways: by using the interactive menu, or the DOS command line. USING THE VGACONF MENU To run the VGACONF utility and display menu of options, type: VGACONF [Enter] To use the VGACONF menu options, move the cursor using the cursor (arrow) keys until the desired selection is highlighted. To make the actual selection, press the [Enter] key. Some menu selections will have sub-menus. To exit a VGACONF program at any time, press[Esc] key to go to the previous menu. Repeat this operation until you are at the main menu. Press [Esc] or select Quit to exit. Select Option is the sub-menu where you can change the option setting. Some options are designed for a specific display mode, that is, CRT, SimulSCAN, or Panel. The following options take effect only in panel mode: Contrast Enhancement, Vertical Position, Cursor, and R.G.B. In SimulSCAN and panel modes reverse may be used. At any time set Display, Bus width, and Inhibit Font. [Note: Bold font is not supported in this system]. USING VGACONG FROM THE DOS COMMAND LINE To quickly change one or more VGA configuration settings, use the command line to invoke VGACONF without using the interactive menu. From the DOS prompt, type: VGACONF [options] [Enter] Where options is one or more option names separated by spaces, these names are listed and described below. -? or -h Help screen -s Give status information -n Disable standby timer -k=xx Set standby timer for keyboard to xx minutes -m=xx Set standby timer for memory to xx minutes ETDG Enable text and disable graphics reverse video NOREVERSE Disable text and graphics reverse video REVERSE Enable text and graphics reverse video DTEG Disable test and enable graphics reverse video ATTREMUL Disable Automap NOATTREMUL Enable Automap BKGND Enable background enhancement FRGRND Enable foreground enhancement BKFRGND Enable background and foreground enhancement EXPAND Enable expand mode NOEXPAND Disable expand mode CENTER Center the screen on the panel TOP Align the screen on the top of the panel BOTTOM Align the screen on the bottom of the panel PANEL Switch the display to the panel CRT Switch the display to the CRT SIMUL Use the panel and the CRT simultaneously 16BIT Enable 16-bit operations NO16BIT Force 8-bit operation INHFONT Inhibit font-loading when switching display NOI Allow font-loading when switching display FULLHGT Select full height cursor NOFULLHGT Select normal cursor W259 Select RGB weighting 2:5:9 W529 Select RGB weighting 5:2:9 W295 Select RGB weighting 2:9:5 W592 Select RGB weighting 5:2:9 W925 Select RGB weighting 9:2:5 W952 Select RGB weighting 9:5:2 All VGACONFIG options can be abbreviated by typing only the first three main characters in the names. 3950/3950C APPENDIX C: VGA SOFTWARE DIRVERS AND UTILITY The C&T 65530 VGA Chip Support Disk includ drives for popular software.
