2100 (250-1624) Utility Software Faxback Doc. # 2582 First, please install the Utility Software by typing: A:[Enter] INSTALL[Enter] (located in the diskette #1 come with your VGA board) The VGA Utilities now are located in the directory you type in INSTALL procedure (such as UTILITY) Following are descriptions of these VGA utilities: CLMODE.EXE Provides the ability to set the standard VGA and extended VGA modes of the VGA, and select the best way to use the VGA for your VGA monitor. CLMODE.DAT Data file used by CLMODE.EXE RIXVIDEO.DSC RIX configuration file VPIC.CFG -VPIC configuration file README -Text about RIXVIDEO and VPIC RAMBIOS.EXE -A RAM resident copy of the VGA video BIOS routines to speed up video operations on access to the BIOS. USING CLMODE.EXE: The CLMODE.EXE -Provides the ability to set the standard VGA and extended VGA modes of the VGA, and select the best way to use the VGA for your VGA monitor. CLMODE.DAT -Data file used by CLMODE.EXE RIXVIDEO.DSC -RIX configuration file VPIC.CFG -VPIC configuration file README -Text about RIXVIDEO and VPIC RAMBIOS.EXE -A RAM resident copy of the VGA video BIOS routines to speed up video operations on access to the BIOS. USING CLMODE.EXE The CLMODE utility allows the user to define the type of monitor attached and set the video modes supported by the Cirrus Logic VGA. Using CLMODE's Menu-Driven Interface At the DOS prompt type: CLMODE[Enter] The main popup window consists of two pull-down menus: Setup and Help. Each pull down menu contains two or more menu items. The underlined letter of a menu item specifies the hot key combination for that item. For example, press the [Alt] and [T] keys simultaneously or just the [T] key to select the Monitor option. Note that a mouse driver must first be installed prior to running the CLMODE utility in order to use the mouse pointer for menu selection. CHOOSING THE ATTACHED MONITOR TYPE Selecting the proper monitor type will allow the VGA to display the highest quality output that it is capable of with the attached monitor. The monitor type determines what video modes will be available to your system. It will also determine the vertical refresh rates available. Generally, the higher the refresh, the better the screen will look. The high refresh option of CLMODE allows the user to force some video modes to a higher refresh rate. The option will not work on some monitors. If high refresh is selected, the user must verify that the connected monitor can support the option by using CLMODE to set video mode 12 and then video mode 3. If you observe any problems in either mode, disable the option by typing" CLMODE 3 m-[Enter] From the directory containing CLMODE.EXE Depending on the monitor that you are using, the high refresh option may have make the display unreadable and you will have to type in the CLMODE command without being able to read it. Select Setup from the main window, then choose the Monitor Type Menu Item. The Monitor Type Setup window will be displayed. The current monitor type and refresh rate will be highlighted initially. Use the keyboard or the mouse to choose the type of monitor attached. To move down to the Refresh Rate Selection box, use the mouse or press the [Tab] key. Press the OK button to set the new monitor type. Press the Cancel button to discard any changes. Press the Help button to get a detailed explanation on the monitor types and the VGA refresh rates. On some systems the monitor type will be remembered from one session to the next. To test this, select a monitor type and exit the CLMODE program. Turn the computer off for ten seconds. After rebooting the computer, run CLMODE and verify whether or not the monitor that you selected is still enabled. If it is, you should not need to set it again in normal use. If the monitor type was not kept then it is necessary to run the CLMODE utility every time that the computer is turned on. The best way to do this is to insert it into the AUTOEXEC.BAT file using the command line options documented below. SETTING THE VIDEO MODE Select Setup from the main window, then choose the Set Mode menu item. The Video Mode Setup window displays all the modes supported according to the monitor type attached and the video memory present. Use the mouse or the keyboard to move the highlighted bar to the video mode desired. To set the mode, press [Alt] and [X] keys, simultaneously, or position the mouse cursor on the Exit button and press the left mouse button. After CLMODE exits back to DOS, the desired video mode will be set. If the monitor type has been changed to a type that does not support the video mode in use when CLMODE was started, CLMODE will default to mode 3+. RETRIEVING THE CURRENT VGA CONTROLLER STATUS The information in the main window displays the VGA controller type, the BIOS version number and the amount of video memory present. GETTING HELP CLMODE provides Help for the following items: Monitor Type, Set Mode, Mouse, Keyboard and About. The Monitor Type help window explains the different capabilities of each monitor type. The Set Mode helps windows define the information given in the Set Mode window. The Keyboard and Mouse help windows explain how to use the keyboard and the moue to make selections. The about window displays the Cirrus Logic copyright message and the CLMODE version number. EXITING THE CLMODE MENU-DRIVEN UTILITY PROGRAM To exit CLMODE at any time, press {Alt} and [F4} keys simultaneously, or click the left mouse button on the system button of the main window (such as the top left corner button of the window which is shown as a dot), or select Setup from the main windows then choose Exit CLMODE. When CLMODE utility exits, the current video mode, monitor type, and VGA refresh rate will be displayed. USING CLMODE's COMMAND LINE OPTIONS When command line options for CLMODE.EXE are given at the DOS prompt, the menu-driven windows will not be displayed, Instead, monitor type, video mode and refresh rate will be set at the DOS prompt. Therefore, CLMODE.EXE can be placed in the autoexec.bat file to automate the configuration process. The command line options for CLMODE.EXE are: CLMODE[[modenum][+*-]][m[montype][refresh]] [modenum] mode number [+*-] +selects 400 lines (default) * selects 350 lines - selects 200 lines [montype] monitor type [refresh] high or low VGA refresh rate (+ or -) Valid monitor types: 0 VGA 1 8514 2 Super VGA (default) 3 Extended Super VGA 4 Multifrequency 5 Extended Multifrequency 6 Super Multifrequency 7 Extended Super Multifrequency Valid VGA refreshes: - Low VGA refresh (default) + High VGA refresh For example, to select mode 3 with high VGA refresh for a Super VGA monitor, type the following command at the DOS prompt: CLMODE 3+M2+[Enter] Typing an invalid option will display the command line help text. Typing S as a command line option will display the current CLMODE settings. NOTE: For monitor type M use LOWERCASE. Following is a table of common monitor types and associated values that you should use for the monitor type option. Resolutions with more then one entry per line in the vertical frequency column signify the availability of the high refresh option.
