Page 32: System I/O Description
Additional software support includes a packet driver with software to allow a full TCP/IP implementation. Serial Ports Pegasus contains two serial ports. Each port is capable of transmitting at speeds up to 115.2Kbaud. Ports COM1 and COM2 are built into the AMD Geode chipset, which are standard 16550 UARTs with 16-byte FIFOs. -
Page 33: Console Redirection To A Serial Port
A serial port on another PC can be connected to the serial port on Pegasus with a null modem cable, and a terminal emulation program, such as HyperTerminal, can be used to establish the connection. -
Page 34: Watchdog Timer
The watchdog timer circuit is programmed via I/O registers located on Page 0: Base +28-31. Flash Memory Pegasus contains a 512KB, 16-bit wide flash memory chip for storage of BIOS and other system configuration data. Backup Battery Pegasus contains an integrated RTC/CMOS RAM backup battery. This battery has a capacity of 120mAH and will last over five years in power-off state. -
