This allows you to use the graphics features provided on your adapter card while accessing the standard VGA signals in the main system board circuitry.
Page 48: Installing Memory Modules
Be sure to follow these guidelines when you install SIMMs: U All SIMMs must be the same capacity U You can install one, two, or four SIMMs; you cannot install three SIMMs Cl Install multiple SIMMs for the best performance; for example, install two 4MB SIMMs instead of one 8MB SIMM tl Install the SIMMs in the sockets closest to the front of the main system board first.
Page 49: Removing Memory Modules
To insert the SIMM, place it in the socket at an angle and firmly press it in. 4. Gently rotate the top of the SIMM toward the front of the main system board until it is vertical and clicks into place in the metal retaining clips.
Page 50: Math Coprocessor
Gently pull away the metal retaining clips securing the SIMM at each end. Do not pull the clips too far, or they may break. As you pull away the clips, the SIMM falls away at an angle. Carefully remove the SIMM and store it in an anti-static bag. 3.
Page 51: Installing A Math Coprocessor
Installing a Math Coprocessor Follow these steps to install a math coprocessor: 1. If necessary, see the main system board map on page 3-2 to locate the math coprocessor socket. 2. Locate the orientation dot in one corner of your coprocessor and turn the coprocessor so that the dot is in the position shown below.
Page 52: Removing A Math Coprocessor
Removing a Math Coprocessor If you need to remove the math coprocessor from your main system board, contact your dealer for assistance. The procedure requires a special extracting tool, and if you try to remove it without this tool you can easily damage it. Cache Module You can install an optional 128KB Intel TurboCache module on your computer’s main system board to expand the amount...
Page 53: Removing A Cache Module
4. Position the cache module so the corner painted white points toward the middle of the main system board. 5. Align the pins on the module with the holes in the connector and then gently push in the module, pressing evenly on all sides.
Page 54: Video Ram
Video RAM Your computer comes with 512KB of video RAM. You can install video RAM chips on your main system board to increase your video memory to 1MB. This enables you to use resolutions up to 1024 x 768 in 256 colors when you connect a monitor capable of displaying that resolution.
Page 55: Removing Video Ram Chips
6. Gently but firmly press the chip into the socket. Check to make sure it is completely seated and that none of the pins are bent. 7. Set the video memory size jumper to indicate the amount of video RAM you now have, as described on page 3-3. 8.
