Check to see if the card is firmly seated in its bus expansion slot. Be sure it is not making contact with any other cards in the system. 2. Be sure your monitor is properly connected to the card. Be sure you monitor's pin definitions match those of your VGA Graphics card. 3. Be sure your system's power supply is operating properly (i.e. fan operates, system power light comes on). 4. If the VGA adaptor is seated on a IBM PC/XT slot or an 8-bit AT slot, be sure J6, J9 and J10 jumpers are connected. 5. If you are using an IBM PC/XT or compatible, check to see your system BIOS is dated October 27, 1982 or later. System BIOS versions prior to this date will not support the adapter card. Special Configuration Requirements for EMS Cards, LAN Cards, and SCSI, ESDI, or RLL Controllers 1. EMS Card: be sure the EMS pages do not conflict with the video RAM space (A0000-DFFFF). If you cannot move the EMS pages out of the A0000-DFFFF area, move Jumper J8 to the disable Autodetect position. 2. LAN Card: If you encounter problems with network products, move Jumper J8 to the Disable Autodetect position. 3. SCSI, ESDI, or RLL Controller. If you encounter problems, move Jumper J8 to the Disable Autodetect position. 4.2 Commonly Asked Questions 4.2.1 Monitors Q. Why does the display shift or change sizes when I switch modes? A. Some monitors lack auto-sizing features or just do not synchronize properly to the video board output. In some cases, horizontal and vertical display adjustments may be necessary. Q. What kind of monitor do I need to display 800x600 or 1024x768 resolution? A. To display 800x600 resolution at 56Hz refresh, your monitor must be capable of a 35.2KHz horizontal scan rate (e.g., NEC 2A, 3D). At 72Hz refresh, your monitor must be capable of a 48.0KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450.) To display 1024x68 interlaced, your monitor must be capable of a 35.5KHz horizontal scan rate (e.g NEC 3D, Seiko 1430 or 1440). To display 1024x768 mon-interlaced, your monitor must be capable of a 48.7KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450). 4.2.2 Systems Q. Can I have two graphics boards in my system at the same time? A. A monochrome card may co-reside with the VGA adapter. You can not have an EGA, CGA, or another VGA and co-resident. Q. I see "mouse droppings" on the screen when I move my mouse around. Is this a problem with my mouse? A. Could be. The version of your mouse driver may not support VGA. Another possibility is that the DRAM on your card is not seated correctly or is not the right speed. If you have added your own DRAM to the card, make sure it is 80 nanosecond Fast Page Mode DRAM. 4.2.3 Software Applications Q. When I run a system utilities program (PC Tools, Norton Utilities, etc.) it tells me I only have 256K of video memory, even though 512K A. Nothing is wrong. System utility programs are designed to detect only the IBM VGA Standard amount of video memory (256K). Q. My display is not correct when I run VPIC or RIX. What's wrong? A. The first thing to check is the software version. VPIC should be version 4.6 or later. RIX must be version 1.38 or later. If you are using an earlier version of VPIC, please contact your software vendors for upgrade information. 4.3 Troubleshooting MS-Windows 4.3.1 Troubleshooting Windows 3.0 and 3.1 This section provides troubleshooting tips for users having problems installing or using the high resolution drivers provided for Windows 3.0 and 3.1. Be sure you have installed the TVGACRTC and SVM utilities on your hard drive before you continue with the troubleshooting proce- dures. NOTE: "Delete driver files" Means delete "VDDTVGA. 386", "T640c.DRV", and "T1024FC.DRV" etc. in C:WINDOWS\SYSTEM directory and "OEMSETUP.INF" in C:\WINDOWS directory. Problem: Windows screen won't come up. It kicks back to DOS prompt. Solution: a. Besure the driver version is the correct one for the Tident chipset on your card (e.g. T1024FC.DRV for TVGA9000 and 8900CL). Be sure the resolution chosen is a match for the amount of memory on- board. (Please refer to REAME.TXT file in WIN subdirectory of your Utility Disk for detail memory requirement.) b. Try adding the statement "EMMEXCLUDE=A000-C7FF" to the (386 enhanced) section of the Windows SYSTEM.INI file. The SYSTEM.INI file is located in the WINDOWS\SYSTEM directory. c. If using QEMM, try adding QEMM exclude statement "DEVICE= QEMM386.SYS X=A000-C7FF" to your CONFIG.SYS file. d. Check CONFIG.SYS and AUTOEXEC.BAT files and minimize TSRs (Terminate and Stay Resident Programs) or Device Driers, such as, DEVICE=TVGABIO.SYS in CONFIG.SYS or PCSHELL.EXE in AUTOEXEC.BAT. e. Delete and reinstall the driver(s). Problem: Windows hangs up during or after installing a driver. Solution: a. Reread installation procedures to be sure you have installed the drivers correctly. b. Did Windows display an error message before hang-up? If no: Check CONFIG.SYS and AUTOEXEC.BAT files and minimize TSRs (Terminate and Stay Resident Programs) or Device Drivers, such as, DEVICE=MOUSE.SYS in CONFIG.SYS or PCTOOLS.EXE in AUTOEXEC.BAT. If SYSTEM.INI (located in the WINDOWS\SYSTEM directory) has been edited, try replacing with a clean version from the original Windows diskettes. If yes: If Windows reports "... file corrupted", delete Trident driver files and use a new set of drivers. If installing on a network via "SETUP/N", you will need to use the "EXPAND" utility (located on original Windows diskettes) to expand the display drivers. If installing on a network and Windows reports "error building WIN.COM", you will need to upgrade to Windows version 3.00a. Problem: Garbage on the screen or double images. Solution: a. Use View Option (F5) in SVM program to verify the problem. Problem: Mouse doesn't function properly. Solution: a. Check mouse connection. b. Contact mouse vendor for latest version of the mouse driver. 4.3.2 Troubleshooting Windows 3.1 This section provides troubleshooting tips for users having problems installing or using the high resolution drivers for Windows 3.1 only. Problem: When changing resolutions by running SETUP, the SETUP menu displays more than one selection for the same resolution mode. Solution: When upgrading to a new set of Windows drivers, you need to delete the old OEM? .INF (e.g. OEM0.INF) file in the WINDOWS\SYSTEM subdirectory. The SETUP menu will then display only one selection for each resolution mode. -------------- | APPENDIX | -------------- Contents Appendix A: Pinout and Sync Frequencies A1.1 Analog color Display Pinouts A1.2 Conversion Table: 9-to-15 Pin A1.3 Video Signals A1.4 Sync and Polarity Specifications Appendix B: DRAM Upgrades Appendix C: Additional Sources for Programming Asistance Appendix D: FCC Compliance Statement Appendix A Pinout and Sync Frequencies A1.1 Analog Color Displaly Pinouts Table 2 shows the VGA Graphics Adapter analog color display pinouts. ------------------------------------------------------- | Pin Function | ------------------------------------------------------| | 1 Red Video (1) | | 2 Green Video (1) | | 3 Blue Video (1) | | 4 Not Used | | 5 Ground | ------------------------------------------------------| | 6 Red Return (ground) | | 7 Green Return (ground) | | 8 Blue Return (ground) | | 9 Key (no pin) | | 10 Sync Retrun (ground) | ------------------------------------------------------| | 11 Monitor ID (not used) | | 12 Monitor ID(2) | | 13 Horizontal Sync | | 14 Vertical Sync | | 15 Not Used | ------------------------------------------------------- (1) Analog monochrome-type monitors use green video for all video input and ignore red video and blue video.

Appendix B DRAM Upgrades The VGA adapter can be configured with two, four or eight pieces of 256Kx4 (80 nanosecond) Fat Page Mode DRAM. Upgrading from two to four DRAM allows you to display up to 1024x768-16 colors. Upgrading from four to eight DRAM allows you to display up to 1024x768-256 colors. It also speeds up the performance by a bit. To purchase DRAM, contact your dealer, a local electronics store, or a mail order house (which advertise in publications such as Computer Shopper, PC Magazine, PC World, and BYTE). Order 256Kx4 Fast Page mode DRAM (sometimes called one megabit DRAM). DRAM speed should be 80 nanoseconds. Upgrading From 256KDRAM to 512K or 1MB 1. Place the adapter component Side up on a firm, flat, non-static surface (avoid wool material). The gold edge connector should be facing you. 2. Insert the DRAM (two pieces if upgrading to 512K and 6 pieces if upgrading to 1 MB) into the sockets provided on the upper left-hand corner of the boards. DRAM should be added in columns according to the diagrams on the next page. The notched side of the DRAM should be facing down. Be careful not to bend the pins. Be sure each DRAM is seated snugly. 3. To check that the DRAM has been installed properly, place the board in your system and turn the system ON. A copyright and the amount of video DRAM detected will appear in the upper left-hand corner of the initial boot screen. If the amount of DRAM detected is the same as the amount installed (512K or 1MB), you have installed the DRAM succefully. If the amount of DRAM detected is 256K, remove the adapter from your system. check to see that all pins fit snugly into their respective socket holes (i.e., no pins bent underneath the DRAM chip or sticking out). Be sure the notches for each DRAM are facing the same way. 256KB DRAM 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � � 旼커 旼커 旼커 幡賞 � � � � � � � � � � � � � � � � � � � � � � 읕켸 읕켸 읕켸 賽賽 � � 旼커 旼커 旼커 幡賞 � � � � � � � � � � � � � � � � � � � � � � 읕켸 읕켸 읕켸 賽賽 � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 ============================================ ------golden finger 512K DRAM 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� � � � 旼커 旼커 幡賞 幡賞 � � � � � � � � � � � � � � � � � � � � � � 읕켸 읕켸 賽賽 賽賽 � � 旼커 旼커 幡賞 幡賞 � � � � � � � � � � � � � � � � � � � � � � 읕켸 읕켸 賽賽 賽賽 � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� ============================================------golden finger 1MB DRAM 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � � 幡賞 幡賞 幡賞 幡賞 � � � � � � � � � � � � � � � � � � � � � � 賽賽 賽賽 賽賽 賽賽 � � 幡賞 幡賞 幡賞 幡賞 � � � � � � � � � � � � � � � � � � � � � � 賽賽 賽賽 賽賽 賽賽 � � � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 ============================================--------golden finger Figure B-1 DRAM Upgrade Appendix C Additional Source for Programming Asistance The information in this manual is intended for quick reference only.
