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.
