Jumpers

The FIRE GL 1000 has two jumpers.

	Jumper	Pins 1-2	Pins 2-3
	JP1	PCI 2.1 even if your system is PCI 2.1 compatible, try this setting only if you experience problems in Windows 95 with the PCI 2.0 setting	PCI 2.0   Standard Setting
	JP2	On board VGA enabled   Standard Setting	On-board VGA disabled   required only if you want to use a VGA controller already present in your system
	Default Settings:	Pins 2 and 3 jumpered for JP1 Pins 1 and 2 jumpered for JP2

It is necessary to ensure that no I/O and memory addresses reserved for the graphics board are used by other hardware devices.

If the on-board VGA controller of your Fire GL 1000 is active, your board uses the following addresses:

	I/O address:
	Standard VGA I/O:	3B0-3DF
	Memory addresses:
	Video RAM	A000-BFFF
	Video ROM	C000-C7FF

Memory Expansion

Importance of Memory Extension

Your Fire GL 1000 is equipped with 4 MB SGRAM or 8 MB SGRAM. These memory sizes are adequate for most applications and requirements.

Extending the memory does not automatically mean that you have access to higher resolutions, faster refresh rates or higher color depths. However, if you want or need 3D capability, or double buffering for 3D applications, 8 MB SGRAM is recommended.

Memory Expansion Modules

Optional memory modules (piggyback boards) are available.

For Fire GL 1000 with 4 MB SGRAM

	Upgrade module:	4 MB SGRAM
	Maximum video memory:	8 MB SGRAM

Adding Memory

Warning!

Prevent static electric damage. Static charges can cause severe damage to microcircuits, but here are some easy ways to see that it doesn't happen:

Hold the graphics card by its edges only. Don't touch edge connectors or exposed circuitry.
Leave cards in anti-static protective bags until ready to install them in your computer.
If possible, ground your body when handling the cards. A metal power supply in your computer is generally considered the best place to ground yourself.
Do not place cards on a metal surface.
Make as few movements as possible to avoid building up static electricity from your clothing, carpets and furniture.

1. With the power off, remove your computer's cover and find your Fire GL 1000 card.
   
   
2. Remove the bracket screw holding your Fire GL 1000 card in place, and carefully remove the card by firmly grasping its top edge pulling upwards.
   
   
3. Lay your card on a flat, non-conductive surface, RAM Module connector side up.
   
   
4. Remove the memory upgrade module from its anti-static container.
   
   
5. Upgrade module orientation: - each upgrade module has two white connectors on its surface. Line up these connectors with the corresponding white connectors (marked with an asterisk * in the illustration below) on your Fire GL 1000 card.
   
   
6. When you have determined that the module has been correctly positioned, press the module into the sockets, firmly and evenly, until the white connectors are snugly and firmly joined together.
   
   
7. Press the piggyback upgrade module evenly until it is fully and snugly seated on the graphics card.
   
   

• Once you have completed installing the RAM, re-install your Fire GL 1000 card into your computer. Refer to Installing the Card.
