Selects serial port transmission speed. The speed must be matched on the other side. Long or noisy lines may require lower speeds.

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.

Send a "Start" signal to start sending data when the receiving buffer is empty. The options are None and Hardware RTS/CTS.

Flow control can prevent data loss from buffer overflow. When sending data, if the receiving buffers are full, a 'stop' signal can be sent to stop the data flow.

Once the buffers are empty, a 'start' signal can be sent to re-start the flow.

Hardware flow control uses two wires to send start/stop signals.

If DHCP is selected, AMI BIOS will search for a DHCP (Dynamic Host Configuration Protocol) server attached to the network and request the next available IP address for this computer.

Station IP Address

This specifies the IPv4 address for the baseboard LAN. There is a separate IPv4 Address field for the dedicated management LAN configuration. When IPv4 addressing is used, the initial value for this field is acquired from the BMC. The IP Source setting determines whether this field is display-only (when Dynamic) or can be edited (when Static).

Subnet Mask

This specifies the IPv4 addressing subnet mask for the baseboard LAN. There is a separate IPv4 Subnet Mask field for the dedicated management LAN configuration.

If IP Source is Static, the default value of Subnet Mask is 0.0.0.0. If cable is connected, and IP Source has been set to be Dynamic, the default value of Subnet Mask which comes from BMC should be 255.255.255.0.

When IPv4 addressing is used, the initial value for this field is acquired from the BMC. The IP Source setting determines whether this field is display-only (when Dynamic) or can be edited (when Static).

When IPv6 addressing is enabled, this field is grayed out and inactive.

Station MAC Address

This specifies the IPv4 addressing gateway IP for the baseboard LAN. There is a separate IPv4 Gateway IP field for the dedicated management LAN configuration.

When IPv4 addressing is used, the initial value for this field is acquired from the BMC. The IP Source setting determines whether this field is display-only (when Dynamic) or can be edited (when Static).

When IPv6 addressing is enabled, this field is grayed out and inactive.

Router IP Address

This specifies the IPv4 addressing gateway IP for the baseboard LAN. There is a separate IPv4 Gateway IP field for the dedicated management LAN configuration.

When IPv4 addressing is used, the initial value for this field is acquired from the BMC. The IP Source setting determines whether this field is display-only (when Dynamic) or can be edited (when Static).

When IPv6 addressing is enabled, this field is grayed out and inactive.

Security

Administrator Password

Set Administrator Password. Administrator password is used if Power On Password is enabled and to control change access in BIOS Setup. Length is 1-14 characters. Case sensitive alphabetic, numeric, and special characters !@#$%^*()-_+=? are allowed. This password controls change access to setup. The administrator has full access to change settings for any setup options, including setting the administrator and user passwords.

User Password

Set User Password. The user password is available only if the administrator password has been installed. This option protects setup settings as well as boot choices. The user password only allows limited access to the setup options, and no choice of boot devices.

Boot

Setup Prompt Timeout

Number of seconds to wait for setup activation key. 65535(0xFFFF) means indefinite waiting.

The number of seconds the BIOS will pause at the end of POST to allow the user to press the [F2] key for entering the BIOS Setup utility. Valid values are 0-65535. A value of 65535 causes the system to go to the Boot Manager menu and wait for user input for every system boot.

Bootup NumLock State

Select the keyboard NumLock state.

Quiet Boot

Use this feature to select the screen between displaying POST messages or the OEM logo at bootup. Select Disabled to display the POST messages. Select Enabled to display the OEM logo instead of the normal POST messages.

Boot mode select

When Boot Mode is Legacy, the BIOS only loads modules required for booting Legacy Operating Systems. When Boot Mode is UEFI, the BIOS only loads modules required for booting UEFI-aware Operating Systems.

Hard Disk Drive BBS Priorities

The Hard Disk Order screen options control the order in which the BIOS attempts to boot from the hard disk drives installed in the system. This screen is only available when there is at least one hard disk device available in the system configuration and the Boot Mode option is set as Legacy. Note that a USB attached hard disk drive or a USB key device formatted as a hard disk appear in this section.

Save_And_Exit

Save Changes and Reset

Reset the system after saving the changes. When you have completed the system configuration changes, select this option to leave the BIOS setup utility and reboot the computer for the new system configuration parameters to take effect. Select Save Changes and Exit from the Exit menu and press Enter.

Discard Change and Exit

Exit setup without saving any changes in BIOS settings. If there have been no changes made in the settings, the BIOS resumes executing POST.

If changes have been made in BIOS settings, a confirmation pop-up appears. If the Discard Changes and Exit action is positively confirmed, all pending changes are discarded and the BIOS resumes executing POST. If the Discard Changes and Exit action is not confirmed, the BIOS resumes executing setup without discarding any changes.

Save Changes

Save all changes made. This will not reset (reboot) the system.

Discard Changes

Discard all the changes and return to the AMI BIOS setup utility.

Restore Defaults

Load manufacturer default settings which are intended for maximum system performance but not for maximum stability.

Save as USER Defaults

Enables the user to save any changes to the BIOS setup for future use.

Restore User Defaults

Retrieve user-defined settings that were saved previously.

Boot Override

This feature allows the user to override the Boot priorities sequence in the Boot menu, and immediately boot the system with a device specified by the user instead of the one specified in the boot list. This is a one-time override.
