SYSTEM BIOS
8.6 USB Legacy Support
The system BIOS ROM checks the USB port, during POST, for the presence of a USB keyboard.
This allows a system with only a USB keyboard to be used during ROM-based setup and also on
a system with an OS that does not include a USB driver.
On such a system a keystroke will generate an SMI and the SMI handler will retrieve the data
from the device and convert it to PS/2 data. The data will be passed to the keyboard controller
and processed as in the PS/2 interface. Changing the delay and/or typematic rate of a USB
keyboard though BIOS function INT 16 is not supported.
8.7 Management Functions
The management functions of the AMD 780V chipset allow a system unit to be managed
remotely over a network. The system BIOS can request the management engine to generate the
following alerts:
■ Temperature alert
■ Fan failure alert
■ Chassis intrusion alert
■ Watchdog timer alert
■ No memory installed alert
