Technical Information 1-5
INTEGRATED GRAPHICS
The system has an ATI GT-B PCI 64-bit 3D multimedia graphics and video controller
integrated on the system board. State of the art techniques are used for optimizing
performance in computer graphic intensive applications and graphical user interfaces (GUI).
Features include:
DDC rev 2b compliance
video acceleration and 3D rendering
full screen Native video playback
2-MB of synchronous graphics random-access memory (SGRAM).
Video Memory
PowerMate P ETC Series systems have 1 MB of SGRAM on the system board and a 1-MB
video upgrade module installed.
Video Resolutions and Refresh Rates
The computer supports the following video resolutions and refresh rates (see Table 1-3).

INTERRUPT CONTROLLER
The interrupt controller operates as an interrupt manager for the entire AT system
environment. The controller accepts requests from peripherals, issues interrupt requests to
the processor, resolves interrupt priorities, and provides vectors for the processor to
determine which interrupt routine to execute. The interrupt controller has priority
assignment modes that can be reconfigured at any time during system operations.
The interrupt levels are described in Table 1-4. Interrupt level assignments 0 through 15 are
in order of decreasing priority. See Section 2 of the PowerMate V & P Series Service and
Reference Manual for information on changing the interrupts using Setup.
