L440GX+ Server Board Product Guide 13
Video
The onboard, integrated Cirrus Logic CL-GD5480 64 bit VGA chip contains an SVGA controller
that is fully compatible with these video standards: CGA, EGA, Hercules
Graphics, MDA, and
VGA. The standard configuration comes with 2 MB of 10 ns onboard Synchronous Graphics
Memory (SGRAM). The video controller supports pixel resolutions of up to 1600 x 1200 and up to
16.7 Million colors.
The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced
and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.
You cannot add video memory to the server board. Depending on the environment, the controller
displays up to 16.7 M colors in some video resolutions. It also provides hardware accelerated bit
block transfers (BITBLT) of data.
SCSI Controller
The embedded Adaptec AIC-7896 dual function SCSI controller provides both Ultra2 (LVDS)
wide and Ultra wide SCSI interfaces as two independent PCI functions. PCI slot 4 is
RAID-upgradeable, providing additional support for the ARO1130U2 RAIDport III controller by
Adaptec.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled.
The onboard device must always be at one end of the bus. The device at the end of the cable must
be terminated. LVDS devices generally do not have termination capabilities. Non-LVDS devices
generally are terminated through a jumper or resistor pack. The SCSI cable (Intel Part Number
745854-003) included with your server board (or integrator’s kit) has been modified to include
active termination. The cable is capable of supporting both Ultra-2 and non-Ultra-2 SCSI devices.
Proper termination of the SCSI bus is required for stable operation of SCSI devices. When
attaching any SCSI device to the cable, verify that they are not terminated. This is usually a
configurable option using a jumper or terminator block on the device. Check the documentation
that came with your SCSI device to verify this option. Termination of the SCSI bus is implemented
using the active termination on the server board along with the active termination at the end of the
SCSI cable.
IDE Controller
IDE is a 16 bit interface for intelligent disk drives with disk controller electronics onboard. The
PCI/ISA/IDE Accelerator, also known as PIIX4e, is a multifunction device on the server board that
acts as a PCI based Fast IDE controller. The device controls:
PIO and IDE DMA/bus master operations
Mode 4 timings
Transfer rates up to 33 MB/s
Buffering for PCI/IDE burst transfers
Master/slave IDE mode
Up to two devices per channel; two channels, IDE0 and IDE1
