Description
Serial
Communication
On without Console
Redirection
Auto
On with Console
Redirection via COM1
On with Console
Redirection via COM2
Off
Configures the BIOS serial console redirection feature and
determines which serial port address would be used (COM1
= 0x3F8, COM2 = 0x2F8). Auto option will enable BIOS
console redirection for the selected device and port address
if a terminal is detected during system startup.
Serial Port
Address
Serial
Device1=COM1,Serial
Device2=COM2
Serial
Device1=COM2,Serial
Device2=COM1
Enables you to set the port address for serial devices.
Note: Only Serial Device 2 can be used for Serial Over LAN
(SOL) feature. To use console redirection by SOL, configure
the same port address for console redirection and the serial
device.
External Serial
Connector
Serial Device 1
Serial Device 2
Remote Access Device
Associates the External Serial Connector to Serial Device 1,
Serial Device 2 or the Remote Access Device.
Note: Only Serial Device 2 can be used for Serial Over LAN
(SOL) feature. To use console redirection by SOL, configure
the same port address for console redirection and the serial
device (refer to Fig 6, 7, and 8).
Failsafe Baud
Rate
115200
57600
19200
9600
Enables you to set the failsafe baud rate for the console
redirection. BIOS attempts to negotiate and determine the
serial baud rate automatically during POST. In case of SOL,
BIOS gets the baud rate value directly from iDRAC. This
failsafe baud rate is used only if the BIOS was not able to
determine the baud rate through either method, auto baud
operation, or iDRAC.
Remote
Terminal Type
VT100/VT220
ANSI
Enables you to select the remote console terminal type. This
must match the emulation mode type in your serial
terminal program (for example, Putty or HyperTerminal).
Redirection
After Boot
Enabled
Disabled
Allows you to enable or disable the BIOS console
redirection after the OS is loaded.
