Video function
The integrated chip set on the system board provides the video function. No
separate VGA subsystem is provided. Video storage uses system dynamic
random-access memory (DRAM), uses technology that provides extra video
memory as needed, and releases it back to the operating system (OS) when not in
use.
Using the BIOS setup, you can allocate memory permanently to system memory or
to video memory.
Models 723 and E23 use an integrated video controller that you can configure to
use up to 64 MB of system DRAM for video storage. It can display resolutions up to
1600x1200 on the primary VGA port, while the secondary VGA port is limited to
1024x768.
Models 743, C43, E43, 783, and E83 use an integrated video controller that you
can configure to use up to 256 MB of system DRAM for video storage. The primary
VGA port supports resolutions up to 2048x1536, while the secondary VGA port is
limited to 1024x768.
Models 784, C84, and E84 use an integrated video controller that uses at least 32
MB and up to 256 MB of system DRAM. If MAXDVMT is selected, then more than
256 MB of DRAM can be used if needed and available. The primary VGA port
supports resolutions up to 1920 X 1080, while the secondary VGA port is limited to
1280 X 1024.
Video drivers are available for many versions of Windows and Linux. Video support
for the 4690 OS, Novell

Linux

Point of Service (NLPOS), and IBM Retail
Environment for SUSE Linux Version 2 (IRES2) is embedded in these operating
systems. DOS uses the video subsystem in standard DOS modes.
Local area network
IBM provides special local area network (LAN) drivers for Models 723, E23, 743,
C43, E43, 783, E83, 784, C84, and E84.
Note: Existing LAN drivers for 4694 and for earlier models of the SurePOS 700 are
not compatible with Models 723, E23, 743, C43, E43, 783, E83, 784, C84,
and E84.
Models 723 and E23 use a 10/100 Mbps Ethernet controller.
Models 743, C43, E43, 783, E83, 784, C84, and E84 use a 10/100/1000 Mbps x1
lane PCI Express (PCI-E) plus TPM Ethernet controller.
The SurePOS 700 Series supports these additional protocols and standards:
v 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 through the use of an additional PCI or PCI-E feature card
or a USB adapter
