Video Function; Local Area Network; Audio And Headphones - IBM 4800-741 Hardware Service Manual

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.
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 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
Other LAN information is as follows:
v Support is provided for Dynamic Host Configuration Protocol (DHCP) and
v Wireless connectivity is offered through the use of an added PCI feature card
v Compatibility is provided for the following industry standards:

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.
