Hi, I have a bit of a problem. I just acquired a 16-bit Trident super VGA card complete with original software. The card seems to be a nice one, but I don't have a manual for it to set the dip switches. It has one block of 6 switches and the Trident chipset. It looks like a Paradise clone and has a couple of identifying numbers on it. The Serial Number is 0038820A and there is another number imprinted on the card that reads as follows: TVGA8816CS_D1. I have another VGA card that I am using, but it is not as good as this the Trident. If anyone can help me with these switches, I will be extremely grateful. Mike Jackson

The dip switches set the monitor selection - "The VGA Graphics Adapter has six-position DIP switch which controls the monitor setting... You can set the VGA to operate with either an analog (PS/2 or Multisync) or Multisync digital (TTL) monitor. Table 1 shows you the proper setting for each type of monitor..." TABLE 1 - Selecting Monitor type Setting 1 2 3 4 5 6 PS/2, Multisync ON ON ON ON N/A N/A monitors (Analog) Multisync OFF ON ON ON N/A N/A TTL monitors (Digital) TABLE 2 - Board Configuration Setting 1 2 3 4 5 6 16-bit data path N/A N/A N/A N/A ON OFF 8-bit data path N/A N/A N/A N/A ON ON "NOTE: The VGA card is shipped with all switches set to ON. Certain personal computers are not fully compatible with the IBM AT Bus standard and cannot runt the VGA Graphics Adapter in 16-bit mode. Therefore, if you install the 16-bit VGA card in a 16-bit slot and encounter any problems booting or operating your system with these settings, please reset switch 6 to OFF" There are also two jumpers that you should be aware of - J1 - EGA, Multisync, CGA and MDA Monitors: If you plan to run an EGA... monitor with the VGA Graphics Adapters and have ordered the ooptional hardware configuration for these monitors you will need to set Jumper J1 to the appropriate monitor setting. You will find J1 located next to the TTL connector on the card. Table 2 shows how to set J1 on the 8-bit or 16-bit VGA card for specialized use with one of these monitors. TABLE 2 Multisync or EGA (If supported) 1 (Factory setting) X 2 X 3 X CGA/MDA (if supported 1X 2X 3X J2 - Automated Bus Size Detection on the 16-bit VGA CARD Jumper J2, located next to the VGA 8800 controller on the 16-bit VGA card controls automatic bus size detection. With automatic bus size detection on the VGA card will sense whether it is an 8-bit or 16-bit slot and will configure the card accordingly. You can either set automatic bus size detection to ON, or set the card for 8-bit BIOS interface. Table 3 illustrates the available settings for J2 on the 16-bit VGA card TABLE 3 - J2 Setting for the 16 bit VGA Card Auto Bus Size Detection ON 3X (Factory setting) 2X 1 X CGA/MDA (if supported 3X 2X 1X Sorry the Jumper settings aren't clear in the manual (hope you don't have to experiment with them - however if you do I hope that the description will at least let you know what it is you are playing with) Good Luck Rick --- {...}isishq!kesrith!rjbeeth | Nepean, Ontario rjbeeth@isishq.fidonet.org
