Version 1.1
B.3.11.18
Flow Control
This feature allows the user to set the flow control for Console Redirection to pre-
vent data loss caused by buffer overflow. Send a “Stop” signal to stop sending 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
(default), Hardware RTS/CTS, and
Software Xon/Xoff.
B.3.12
ACPI Settings
Use this feature to configure Advanced Configuration and Power Interface (ACPI)
power management settings for your system.
B.3.12.1
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 instruction. Power to
the CPUs and RAM is maintained, but RAM is refreshed. Select Suspend Disabled
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)
(default), S3 (Suspend to RAM)(X9DRG-QF), and Sus-
pend Disabled.
B.3.12.2
NUMA
This feature enables the Non-Uniform Memory Access ACPI support. The options
are
Enabled
(default), and Disabled.
B.3.12.3
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 depen-
dency on other timestamp calculation devices, such as an x86 RDTSC Instruction
embedded in the CPU. The High Performance Event Timer is used to replace the
8254 Programmable Interval Timer. The options are
Enabled
(default) and Dis-
abled.
Trusted Computing
Available when a TPM device is detected by the BIOS.
