6.1.1 System Firmware
The system firmware provides support for the following operating systems:
• DIGITAL UNIX and OpenVMS Alpha are supported under the SRM console,
which can be serial or graphical. The SRM firmware is in compliance with the
Alpha System Reference Manual (SRM).
• Microsoft Windows NT is supported under the AlphaBIOS console. Refer to the
