Menu Item Description
Memory Mapped I/O above
4GB
Allows you to enable support for PCIe devices that require large amounts
of memory. By default, the option is set to Enabled.
Slot Disablement Allows you to enable or disable available PCIe slots on your system. The
Slot Disablement feature controls the configuration of PCIe cards
installed in the specified slot. Slot disablement must be used only when
the installed peripheral card is preventing booting into the operating
system or causing delays in system startup. If the slot is disabled, both the
Option ROM and UEFI driver are disabled.
Serial Communication screen
You can use the Serial Communication screen to view the properties of the serial communication port.
You can view the Serial Communication screen by clicking System Setup Main Menu → System BIOS →
Serial Communication.
Menu Item Description
Serial Communication Selects serial communication devices (Serial Device 1 and Serial Device 2)
in the BIOS. BIOS console redirection can also be enabled and the port
address can be specified. By default, Serial Communication option is set
to Auto.
Serial Port Address Enables you to set the port address for serial devices. By default, the
Serial Port Address option is set to Serial Device 1=COM2, Serial Device
2=COM1
NOTE: You can use only Serial Device 2 for the Serial Over LAN
(SOL) feature. To use console redirection by SOL, configure the
same port address for console redirection and the serial device.
NOTE: Every time the system boots, the BIOS syncs the serial MUX
setting saved in iDRAC. The serial MUX setting can independently be
changed in iDRAC. Therefore, loading the BIOS default settings from
within the BIOS setup utility may not always revert this setting to the
default setting of Serial Device 1.
External Serial Connector You can associate the External Serial Connector to Serial Device 1, Serial
Device 2, or the Remote Access Device using this field.
NOTE: Only Serial Device 2 can be used for (Serial Over LAN) SOL.
To use console redirection by SOL, configure the same port address
for console redirection and the serial device.
NOTE: Every time the system boots, the BIOS syncs the serial MUX
setting saved in iDRAC. The serial MUX setting can independently be
changed in iDRAC. Therefore, loading the BIOS default settings from
within the BIOS setup utility may not always revert this setting to the
default setting of Serial Device 1.
Failsafe Baud Rate Displays the failsafe baud rate for console redirection. The BIOS attempts
to determine the baud rate automatically. This failsafe baud rate is used
only if the attempt fails, and the value must not be changed. By default,
the Failsafe Baud Rate option is set to 115200.
Remote Terminal Type Sets the remote console terminal type. By default, the Remote Terminal
Type option is set to VT 100/VT 220.
