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.

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.

Local area network
IBM provides special local area network (LAN) drivers for the SurePOS Models
721/741/781 and 722/742/782, 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 Models 721/741/781 and 722/742/782.
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 Models 721/741/781 and 722/742/782 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.
