Video

The onboard super VGA controller (PCI) is a high-performance SVGA
subsystem that supports:
T
BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and
MDA
T
2 MB of Video Memory
T
16-bit bus for high-speed display memory access
T
Hardware accelerated bit block transfers (BITBLT)
T
72Hz refresh, non-interlaced at: 640x480, 800x600, or 1280x1024
resolutions
T
Up to 16M colors at 640x480 and 800x600 resolutions, 64K colors at
1024x768 resolutions and 256 colors at 1280x1024 resolutions with the
optional 2 MB video memory.
Note: SVGA drivers may be required to use the high-
performance video modes.

SCSI Controller

The system I/O board includes a dual Symbios Ultra2 wide SCSI-3 controller
integrated as a PCI bus master. This controller supports data paths of 8-bit
(fast/narrow SCSI) at a data transfer rate of 10 MB/sec and 16-bit (fast/wide or
ultra /wide SCSI) at a data transfer rate of 20 MB/sec or 40 MB/sec. As a PCI
bus master, this controller supports burst data transfer rates up to the maximum
of 133 MB/sec.
On this server, Channel 1 is cabled to SCSI devices in the removable media
drive bays. Channel 2 is available for optional external SCSI devices.

Peripheral Controller

The advanced integrated peripheral controller supports two serial ports and one
parallel port through the I/O riser board (see Figure 1-6, A). The advanced
integrated peripheral controller also supports the connection of two diskette
drives (see Figure 1-6, I).

External Device Connectors

The I/O panel provides connectors for a PS/2 compatible mouse and a keyboard,
connectors for VGA monitor, two serial port connectors, a parallel port
connector and two USB interface connectors. It also provides a narrow SCSI
external connector.
