STL2 Server Board Architecture Overview STL2 Server Board TPS

∙Integrated physical interface to TX magnetics.

∙The magnetics component terminates the 100Base-TX connector interface. A flash device stores the network ID.

∙Support for Wake-on-LAN (WOL).

2.4.2.2Video Controller

The STL2 server board includes an ATI Rage IIC video controller, 4 MB video SGRAM, and support circuitry for an embedded SVGA video subsystem. The Rage IIC, 64-bit VGA Graphics Accelerator contains a SVGA video controller, clock generator, BitBLT engine, and RAMDAC. Two 512K x 32 SGRAM chips provide 4 MB of 10ns video memory.

The SVGA subsystem supports a variety of modes: up to 1280 X 1024 resolution, and up to

16.7Million colors. It also supports analog VGA monitors, single- and multi-frequency, interlaced and non-interlaced, up to 100 Hz vertical refresh frequency. The STL2 server board provides a standard 15-pin VGA connector, and external video blanking logic for server management console redirection support.

2.4.2.2.1Video Controller PCI Signals

The Rage IIC supports a minimal set of 32-bit PCI signals because it never acts as a PCI master. As a PCI slave, the device requires no arbitration or interrupts.
