Adapters and Internal Drives
Matrox MGA Millennium Graphics Adapter
If a Matrox MGA Millennium Graphics Adapter comes standard in the computer, the following major
features are provided:
±
4 MB of Windows RAM (WRAM), upgradable to 8 MB
±
One 15-pin monitor connector
±
One multimedia connector for attaching video devices
±
Support for all VGA modes
±
VESA 2.0 compliance for SVGA modes
±
Video POST/BIOS code
The following table shows the system resources used by the Matrox MGA Millennium Graphics Adapter.
Note:
When the computer is started, the resource assignments are subject to change during the
power-on self-test (POST).
SCSI Adapter
Some models come with the Adaptec AHA-2940 Ultra Wide SCSI Adapter.
This adapter provides the
interface between the PCI bus and SCSI devices.
Multiple internal and external drives can be attached to
the SCSI adapter.
SCSI technology is useful with multitasking operating environments because
instructions can be sent concurrently to every drive in the system.
The Adaptec AHA-2940 Ultra Wide
SCSI Adapter has:
±
One external 68-pin, 16-bit connector
±
One internal 50-pin, 8-bit connector
±
One internal 68-pin, 16-bit connector
Up to a total of fifteen internal and external SCSI devices can be attached to the SCSI adapter, but the
number of internal devices installed is dependent upon the number of drive bays available.
The PC
365
has five drive bays.
Note:
A maximum of three internal SCSI hard disk drives are supported with the standard PD/CD-ROM
drive installed.
A maximum of four internal hard disk drives are supported when Ultra SCSI hard
disk drives are installed.
An extra cable is provided with SCSI models.
This cable provides five identical connectors for attaching
the SCSI adapter to internal SCSI devices.
For more information on connecting SCSI devices, see the
Adaptec SCSI Support Package
