standby mode. Intel’s robust implementation requires no
jumpers to set up.
Feature-rich Products
for Maximum Flexibility
With Desktop Boards D845EPT2 and D845EBG2, system
integrators can design and build custom configurations to
meet their customers’ specific technology requirements
while maintaining the flexibility to alter or upgrade later.
Desktop Boards D845EPT2 and D845EBG2 offer the choice
of a Communications and Networking Riser (CNR) or Intel®
PRO/100 network connection. Three PCI slots on Desktop
Board D845EPT2 (microATX) and six PCI slots on Desktop
Board D845EBG2 (ATX) allow further expansion of the
boards’ capabilities, and an AGP slot enables customized
graphics solutions. A high performance audio solution
featuring SoundMAX* with SPX delivers exceptional sound
and the flexibility to upgrade to multi-channel playback
using CNR cards. User satisfaction and expanded system
performance are enhanced through Intel®Rapid BIOS Boot,
six USB 2.0 ports (four on the back panel and two to the
front panel), and Ultra ATA/100 disk support.
Complete Solutions in the Box
From e-Commerce to creating personal music libraries,
business and personal users are driving demand for a variety
of complex applications. To ensure that today’s PCs are
ready for the digital world, Intel desktop boards now come
