Integrated Graphics Processor
6.3 Upgrading
All systems provide direct, dual-monitor support; a VGA montor and a DVI monitor can be
connected and driven simultaneously. These systems also include a PCIe x16 graphics slot that
specifically supports a PCIe x16 graphics card.
The normal upgrade procedure for these systems is as follows:
1. Shut down the system through the operating system.
2. Unplug the power cord from the rear of the system unit.
3. Remove the chassis cover.
4. Install the graphics card into the PCIe x16 graphics slot.
5. Replace the chassis cover.
6. Reconnect the power cord to the system unit.
7. Power up the system unit:
✎
If an ATI graphics card with SurroundView enabled is installed in the PCIe x16 graphics slot, the
ROM-Based Setup Utility (RBSU) allows the user the choice of leaving the IGP enabled to drive
multiple video monitors or disable the IGP and using only the discrete graphics card. If the IGP
is enabled, the user also has the choice of selecting which graphics controller is the prime (boot)
device.
✎
If a graphics card is installed in the PCIe x1 slot, the BIOS will disable the IGP by default, but
can be re-enabled through the RBSU to allow an alternate method of multi-monitor operation.
Press the
F10 key during the boot process to enter the ROM-based Setup utility and re-enable the
IGP for multi-monitor operation.
