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 Trio64V+ 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

The following table shows the system resources used by the S3 Trio64V+ SVGA Graphics Adapter.

Note: When the computer is started, the resource assignments are subject to change during the

power-on self-test (POST).
