Intel Desktop Board D2500HN Technical Product Specification 1.5 Intel® NM10 Express Chipset The Intel NM10 Express Chipset provides interfaces to the processor and the USB, SATA, LPC, LAN, PCI, and PCI Express interfaces. The Intel NM10 Express Chipset is a centralized controller for the board's I/O paths. NOTE The board is designed to be passively cooled in a properly ventilated chassis. Chassis venting locations are recommended above the processor heatsink area for maximum heat dissipation effectiveness. For information about The Intel NM10 Express chipset Resources used by the chipset Refer to http://www.intel.com/products/desktop/chipsets/index.htm Chapter 2 1.5.1.1 Video Memory Allocation Video memory is allocated from the total available system memory for the efficient balancing of 2-D/3-D graphics performance and overall system performance. Dynamic allocation of system memory to video memory is as follows: • 256 MB total RAM results in 32 MB video RAM • 512 MB total RAM results in 64 MB video RAM • 1 GB total RAM results in 128 MB video RAM • 2 GB total RAM results in 224 MB video RAM 1.5.1.2 Analog Display (VGA) The VGA port supports analog displays. The maximum supported resolution is 1920 x 1200 (WUXGA) at a 60 Hz refresh rate. The VGA port is enabled for POST whenever a monitor is attached. 1.5.1.3 Configuration Modes For monitors attached to the VGA port, video modes supported by this board are based on the Extended Display Identification Data (EDID) protocol. 20
