512 KB and is not upgradable.
1.3.6 Graphics Controllers
The purpose of a graphics controller is to generate the text and graphics images for the monitor
screen. The quality of the picture you see depends on the resolution of the monitor, the number of
colors the graphics controller can display, and the amount of graphics memory available. High
resolution graphics with many colors require that the graphics controller have its own memory
system.
The Pentium computers come with the S3 Trio64V2/GX Enhanced 64-bit graphics controller
integrated onto the system board and have 1 MB of SGRAM installed. Graphics memory on these
models may be upgraded to 2 MB with the addition of an optional memory module.
The Pentium II computer comes with the Matrox MGA-1064SG graphics accelerator integrated onto
the system board and has 2 MB of SGRAM installed. Graphics memory on these models may be
upgraded to 4 MB with the addition of an optional memory module.
Supported screen resolutions for the controller are listed in Chapter 8, “Specifications.”
