System Configuration and Setup

Console Port Configurations

Power-up information is typically displayed on the system's console terminal. The console
terminal may be either a graphics monitor or a serial terminal. If you use a serial terminal,
it is connected through the COM1 (MMJ) serial port.
Several SRM console environment variables are used to configure the console ports:
Environment Variable
console
tt_allow_login
In addition, the tga_sync_green environment variable is used to synchronize monitors
using the high-performance turbo graphics adapter card (PBXGA).
A serial terminal can also be configured to run the ECU or interface with the AlphaBIOS
console. (See the following sections.)
When using a VGA controller other than the standard onboard VGA, refer to the final
section in this chapter.
