Terminal Type
This feature allows the user to select the target terminal emulation type for Con-
sole Redirection. Select VT100 to use the ASCII character set. Select VT100+
to add color and function key support. Select ANSI to use the extended ASCII
character set. Select VT-UTF8 to use UTF8 encoding to map Unicode characters
into one or more bytes. The options are ANSI, VT100, VT100+, and VT-UTF8.
Bits Per Second
This item sets the transmission speed for a serial port used in Console Redirec-
tion. Make sure that the same speed is used in the host computer and the client
computer. A lower transmission speed may be required for long and busy lines.
The options are 9600, 19200, 57600, and 115200 (bits per second).
Flow Control
This feature allows the user to set the fl ow control for Console Redirection to
prevent data loss caused by buffer overfl ow. Send a "Stop" signal to stop send-
ing data when the receiving buffer is full. Send a "Start" signal to start sending
data when the receiving buffer is empty. The options are None, Hardware RTS/
CTS, and Software Xon/Xoff.
ACPI Settings
Use this feature to confi gure Advanced Confi guration and Power Interface (ACPI)
power management settings for your system.
ACPI Sleep State
Use this feature to select the ACPI State when the system is in sleep mode. Select
S1 (CPU_Stop_Clock) to erase all CPU caches and stop executing instructions.
Power to the CPU(s) and RAM is maintained, but RAM is refreshed. Select Suspend
to use power-reduced mode. Power will only be supplied to limited components
(such as RAMs) to maintain the most critical functions of the system. The options
are S1 (CPU_Stop_Clock), and Suspend Disabled.
NUMA (NON-Uniform Memory Access)
This feature enables the Non-Uniform Memory Access ACPI support. The options
are Enabled and Disabled.
High Precision Event Timer
Select Enabled to activate the High Precision Event Timer (HPET) that produces
periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does
in synchronizing multimedia streams, providing smooth playback, reducing the de-
pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc-
