Video Controller
The 69030 video controller features a 64-bit graphics engine, with 24-bit RAMDAC for
true color support. It has 4 MB of VRAM and supports resolutions of up to 1600x1200
and up to 16 million colors (24-bit). The video controller resides on the AGP port and
provides 1x acceleration, which is a bus speed of 66 MHz (twice as fast as on the
PCIbus). The maximum video modes supported are listed in the following table. The
highest supported interlaced monitor mode is 1280x1024, 16-bit/65k color, and 43 Hz.
Video output is available on the front panel through a standard 15-pin D shell connector. Ethernet Controller
The XVME-660 uses an Intel 82559ER 10 Base-T/100 Base-TX Ethernet controller with
a 32-bit PCI bus mastering interface to sustain 100 Mbits per second bus transfers. The
RJ-45 connector on the module's front panel provides autosensing for 10Base-T and
100Base-TX connections. The RJ-45 connector has two indicator lights. When mounted
vertically, the top light (the one closer to the USB port) is the link/activity light and the bottom light (the one closer to the COM ports) is the 10Base-T/100Base-TX indicator.
When it is off, the connection is 10Base-T; when it is on, the connection is 100Base-TX.
SCSI Controller
The Symbios 53C875J SCSI I/O processor provides an UltraSCSI interface with 32-bit
bus mastering to the PCIbus. This highly integrated UltraSCSI controller contains a SCSI
engine that provides autoexecution of SCSI commands, freeing the host CPU to perform
other tasks. It is capable of supporting transfer rates up to FAST 40 MB per second on a
wide (16-bit) bus. The transfer rate can be slowed down as needed for backward compatibility through the SCSI Device Management System (SDMS) utility, which is embedded in the SCSI BIOS. A serial EPROM is used to store any changes mad by the utility.
The SCSI BIOS is enabled or disabled in the Daughter SCSI PCI submenu of the PCI Configuration submenu of the Advanced menu in the system BIOS (p. 48). You can enter the
SCSI BIOS during boot up by pressing CTRL-C at the correct prompt. Jumpers J8 and J9
on the daughterboard affect the SCSI controller, but should not be changed under normal
operation.
The SCSI interface allows booting from a SCSI device such as a hard drive or a CDROM. The device must be configured correctly in the SCSI BIOS. PCI Local Bus Interface
The PIIX4 PCI-to-ISA bridge device provides an accelerated PCI-to-ISA interface that
integrates a high-performance enhanced IDE controller, PCI and ISA master/slave interfaces, enhanced DMA functions, UltraDMA 33 support, USB support, and a
plug-and-play port for onboard devices. The bridge device also provides many common
I/O functions found in ISA-based systems, including two 87C37 DMA controllers that
provide seven channels, two 82C59 interrupt controllers, and an 82C54 timer/counter.
Universal Serial Bus Port
The XVME-660 incorporate one Universal Serial Bus (USB) port compatible with USB
devices. The port terminates in a standard two-pin connector.
Fast IDE controller and Floppy Drive Controller
The enhanced IDE controller supports programmed I/O (PIO), bus mastering DMA with
transfer rates to 22 MB/second, and UltraDMA 33 (33 MB/second). The controller contains an 8 x 32 bit buffer for bus master IDE PCI burst transfers, and will support up to
two IDE devices. This controller can also handle a single optional floppy drive device. If
present, this floppy drive will be designated Drive A.
