Updated July 14, 2008 Video function The integrated chipset on the system board provides the video function. Video storage uses system DRAM and utilizes technology that provides extra video memory as needed and releases it back to the operating system when not in use.1 Using the BIOS setup, you can permanently allocate memory to system memory or to video memory. All video subsystems support modes up to 1600 x 1200 resolution. Video drivers are available for many versions of Windows and Linux; support for the 4690 is embedded in the operating system. DOS uses the video subsystem in standard DOS modes.1 Local area network IBM provides special local area network (LAN) drivers for the SurePOS 720, without requiring different drivers for different boards. The product is shipped with integrated, auto-sensing 10/100 Mbps Ethernet support and uses Intel LAN hardware. Note: Existing LAN drivers for 4694, and earlier models of 4800 are not compatible with SurePOS 720. Other LAN information is as follows: v Support is provided for Dynamic Host Configuration Protocol (DHCP) and Preboot Execution Environment (PXE), but not for the Remote Program Load (RPL) or Novell NetWare protocols v Wireless connectivity is offered through the use of an added PCI feature card v Compatibility is provided for the following industry standards: - IEEE 802.3i 10Base-T/100Base-T physical layer interface - IEEE 802.3u auto negotiation Audio and headphones The SurePOS 720 of products contain an AC97 compatible audio subsystem. The product is capable of driving conventional speakers or headphones with the line-out output, but cannot drive non-powered speakers (such as the early models of the 4820 display with optional speaker kit). Connecting headphones to the front audio jack disconnects the line-out jack on the rear. PC speaker tones are coupled into the audio subsystem (line-out). Note: The front headphone jack is not available on Models 721 and 722. 1. Depends upon your operating system. Chapter 1. Introducing the SurePOS 700 Models 15

contain
an
AC97
compatible
audio
subsystem.
The
product
is
capable
of
driving
conventional
speakers
or
headphones
with
the
line-out
output,
but
cannot
drive
non-powered
speakers
(such
as
the
early
models
of
the
4820
display
with
optional
speaker
kit).
Connecting
headphones
to
the
front
audio
jack
disconnects
the
line-out
jack
on
the
rear.
PC
speaker
tones
are
coupled
into
the
