Chapter 3. Adapters and Internal Drives
The PC 365 comes standard with a graphics adapter and, in some models, a SCSI adapter. The
graphics adapter provides support for video, and the SCSI adapter provides an interface between the PCI
bus and SCSI devices.
Note: The IBM PCMCIA adapter for PCI or an IDE expansion adapter is not supported.
Graphics Adapters
The video subsystem is provided by one of two types of graphics adapters: the S3 SVGA
Graphics Adapter or the Matrox MGA Millennium Graphics Adapter. Each adapter plugs into the riser card
and connects to the PCI bus; both adapters are compliant with
PCI Local Bus Specification 2.1. (For more
information on the riser card, see “Riser Card” on page 13.) The graphics adapters support DDC 1.1 and
DDC 2B standards.
Also, each adapter provides a 15-pin monitor connector (the Matrox MGA Millennium Graphics Adapter
also provides a multimedia connector for attaching optional video features).
Instructions for installing device drivers for each graphics adapter are provided in S3 SVGA
Device Driver Installation Instructions and Matrox MGA Millennium Graphics Adapter Software Installation
Guide.
S3 SVGA Graphics Adapter
If an S3 SVGA Graphics Adapter comes standard in the computer, the following major features
are provided:
Ÿ
2 MB of 60 ns EDO DRAM
Ÿ
One monitor connector
Ÿ
Support for all VGA modes
Ÿ
VESA 1.2 compliance for SVGA modes
Ÿ
Complete Plug and Play support
Ÿ
Local peripheral bus interface
The following table shows the system resources used by the S3 SVGA Graphics Adapter.
Note: When the computer is started, the resource assignments are subject to change during the
power-on self-test (POST).
