Flow Control
Use this item to set the flow control for Console Redirection to prevent 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, Hardware RTS/CTS, and Software Xon/Xoff.
Data Bits
Use this feature to set the data transmission size for Console Redirection. The
options are 7 (Bits) and 8 (Bits).
Parity
A parity bit can be sent along with regular data bits to detect data transmission
errors. Select Even if the parity bit is set to 0, and the number of 1's in data bits
is even. Select Odd if the parity bit is set to 0, and the number of 1's in data bits
is odd. Select None if you do not want to send a parity bit with your data bits in
transmission. Select Mark to add a mark as a parity bit to be sent along with the
data bits. Select Space to add a Space as a parity bit to be sent with your data
bits. The options are None, Even, Odd, Mark and Space.
Stop Bits
A stop bit indicates the end of a serial data packet. Select 1 Stop Bit for standard
serial data communication. Select 2 Stop Bits if slower devices are used. The
options are 1 and 2.

WHEA Support
This feature Enables the Windows Hardware Error Architecture (WHEA) support for
the Windows 2008 (or a later version) operating system. The options are Enabled
and Disabled.
High Precision Event Timer
Select Enabled to activate the High Performance 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 and reducing
the dependency 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 and
Disabled.
PCI AER Support
