3.2.2.2 Intel
®
Embedded Server RAID Technology Option ROM
The Intel
®
Embedded Server RAID Technology for SATA Option ROM provides a pre-OS user
interface for the Intel
®
Embedded Server RAID Technology implementation and provides the
ability for an Intel
®
Embedded Server RAID Technology volume to be used as a boot disk as
well as to detect any faults in the Intel
®
Embedded Server RAID Technology volume(s) attached
to the Intel
®
RAID controller.
3.2.3 Parallel ATA (PATA) Support
The integrated IDE controller of the ESB-2 ICH6 provides one IDE channel. It redefines signals
on the IDE cable to allow both host and target throttling of data and transfer rates of up to
100MB/s. For this server board, the IDE channel was designed to provide Slim-line Optical
Drive support to the platform. The BIOS initializes and supports ATAPI devices such as
CDROM, CD-RW and DVD. The IDE channel is accessed through a single high density 44-pin
connector ((J3G1) which provides both power and IO signals. The ATA channel can be
configured and enabled or disabled by accessing the BIOS Setup Utility during POST.
Note: The IDE connector on this server board is NOT a standard 40 IDE connector.
Instead, this
connector has an additional 4 power pins over and above the standard 40 I/O pins. The design
intent of this connector is to provide support for a slim-line optical drive only.
3.2.4 USB 2.0 Support
The USB controller functionality integrated into ESB-2 provides the server board with the
interface for up to eight USB 2.0 ports. Two external connectors are located on the back edge of
the server board.
One internal 2x5 header is provided, capable of supporting two optional USB
2.0 ports.
Three USB ports are routed through the bridge board connector providing optional
USB support for a system Control Panel or other USB requirements. An additional USB port is
dedicated to the Intel
®
Remote Management Module (Intel
®
RMM) connector.
3.3 Video Support
The server board provides an ATI* ES1000 PCI graphics accelerator, along with 16MB of video
DDR SDRAM and support circuitry for an embedded SVGA video sub-system. The ATI ES1000
chip contains an SVGA video controller, clock generator, 2D engine, and RAMDAC in a 359-pin
BGA. One 4Mx16x4 bank DDR SDRAM chip provides 16MB of video memory.
The SVGA sub-system supports a variety of modes, up to 1024 x 768 resolution in 8/16/32bpp
modes under 2D. It also supports both CRT and LCD monitors up to a 100 Hz vertical
refresh rate.
Video is accessed using a standard 15-pin VGA connector found on the back edge of the server
board. Video signals are also made available through the 120-pin bridgeboard connector which
provides signals for an optional video connector to be present on the platform’s control panel.
Video is routed to both the rear video connector and a control panel video connector.
Video is
present at both connectors simultaneously and cannot be disabled at either connector
individually.
Hot plugging the video while the system is still running is supported.
On-board video can be disabled using the BIOS Setup Utility or when an add-in video card is
installed. System BIOS also provides the option for dual video operation when an add-in video
card is configured in the system.
3.3.1.1 Video Modes
The ATI ES1000 chip supports all standard IBM* VGA modes. The following table shows the 2D
modes supported for both CRT and LCD.
