ESM-2740/2743
18 ESM-2740/2743 User’s Manual
• Three USB host controllers provide high performance peripherals with 480 Mbps of
bandwidth, while enabling support for up to six USB 2.0 ports. This results in a
significant increase over previous integrated 1-4 port hubs at 12 Mbps
• The latest AC ’97 implementation delivers 20-bit audio for enhanced sound quality
and full surround sound capability. Integrated audio solutions continue to enjoy
success as a very cost-effective, yet high-performance solution
• LAN Connect Interface (LCI) provides flexible network solutions such as 10/100
Mbps Ethernet and 10/100 Mbps Ethernet with LAN manageability
• Dual Ultra ATA/100 controllers, coupled with the Intel® Application Accelerator – a
performance software package – support faster IDE transfers to storage devices
• Intel Application Accelerator software provides additional performance over native
ATA drivers by improving I/O transfer rates and enabling faster O/S load time,
resulting in accelerated boot times
• Communication and Network Riser (CNR) offers flexibility in system configuration
with a baseline feature set that can be upgraded with an audio card, modem card, or
network card
