3 BIOS WARNING: Changing the BIOS may be detrimental to platform operations if the changes are not fully understood. Before you change the BIOS, if you have questions, contact your Dell EMC technical representative. For the most current BIOS update information, see the VEP4600 Release Notes.
Figure 3. BIOS setup How to boot into BIOS settings after upgrade After upgrading BIOS to the latest release 1. Booting into BIOS settings prompts the user to type in BIOS administrator password. 2. The default BIOS administrator password is ! For example if the service tag is: GWGRG02 then the password is GWGRG02! NOTE: Press enter to skip the password. The BIOS enters read-only mode. Many configuration entries become readonly, not configurable, see the following screenshot.
3. Navigate to the boot tab. You can still boot into all the eligible boot options, see the following boot option menu. 4. Navigate to the Save & Exit tab.
There are several ways to retrieve VEP product service tag. How to retrieve a VEP4600 product service tag Retrieve service tag from BMC, DIAG OS, and luggage tag Finding service tag through BMC ● Log in and run the following command from the BMC console. ipmitool -I lanplus -H 127.0.0.1 -U admin -P admin fru print | grep "Product Serial" MC1 not present, ignore FRU MC1 not present, ignore FRU Product Serial : GWNRG02 Finding service tag through DIAG OS ● Boot into DIAG OS and run the following command.
How to change the default BIOS password 1. Boot into BIOS settings, enter the default password 2. Browse the Security tab. 3. Press enter on Administrator Password.
NOTE: If you press enter with no password, the following appear. 4. Select Yes to confirm the old password erased. Once saved and rebooted, no more password required for the subsequent BIOS setting sessions.
5. Enter the same password again to confirm. 6. Browse the Save & Exit tab and press enter on Save Changes and Exit.
Password reset Steps to set password to ! . Unified firmware updater admin password reset An admin user can reset the password in the United firmware updater v3.2. NOTE: This functionality is only for an admin user. NOTE: No password is required for a user account. The following steps permit an user to reset an admin password to the default ! password. 1. 2. 3. 4. 16 Select either Delete or F2 to go to the setup menu . Press enter to get into the user account.
NOTE: The Unified firmware updater retains an admin old password during the Unified firmware updater update by default if there is a password setup before the update. NOTE: The Unified firmware updater tool cannot recover the admin user's old password if the user has forgotten it. Hardware flow control Hardware flow control is not enabled on the console port by default. Follow the steps below in BIOS settings to enable the hardware flow control for the console port. 1. Select the Boot menu tab.
Figure 4. BIOS main screen 2. Select Advanced then COM0 (Console Redirection Settings) and Hardware RTS/CTS in the Flow Control popup menu.
Figure 5. Advanced tab Figure 6.
Figure 7. Hardware RTS/CTS 3. Press F4 to save and exit BIOS. Super IO configuration The VEP4600 only has the serial port on the Super I/O (SIO) chip. The chip settings are preconfigured and normally do not need changing. However, you can use the BIOS to change the Super I/O chip settings, such as the I/O Base, interrupt request line (IRQ), and direct memory access (DMA) channel. To access these settings, from the BIOS setup screen, select the Advanced tab, then select SIO Configuration.
Figure 8. Super I/O configuration Figure 9. Super IO configuration Boot order The BIOS looks for a bootable image in the Boot order setting order list. The BIOS then loads and boots the image. To access the boot order setting, from the BIOS setup screen, select the Boot tab, then select Boot Option Priorities.
Figure 10. Boot order Server management VEP4600 has an on-board baseboard management controller (BMC) to monitor system health. During Boot up, the BIOS communicates with the BMC and exchanges messages with the BMC to log events, get BMC self-test results, and configure BMC network parameters. To configure BMC to use Static IP or dynamic host configuration protocol (DHCP), use the BIOS. To access BMC settings, from the BIOS setup screen, select the Server Mgmt tab, then BMC Network Configuration.
After an event, the BIOS logs a message to the BMC. The BMC stores these messages in nonvolatile storage. Apart from the BIOS, health monitoring software and system software also logs messages to the BMC system event log (SEL). View these messages from the BIOS setup screen, select the Server Mgmt tab, then select View System Event Log. Figure 12. View system event logs You can add, delete, access, or modify user rights.
Option ROM dispatch policy Option read-only memory (ROMs) contain firmware that the BIOS executes. The values listed on this screen and in the Compatibility Support Module screen use default values when the Restore if Failure setting is true and the BIOS fails to boot up. NOTE: Changing the option ROM settings may effect the BIOS boot up. Dell EMC recommends keeping the default value of Restore if Failure equals true.
● Scroll down and select the X710 interface card. ● Select Device Level Configuration and press the enter key for the selected X710 card.
● Select Virtualization Mode for device level configuration and press the enter key. ● Select SR-IOV in the Virtualization Mode popup menu and press the enter key.
USB 3.0 To support universal serial bus (USB) 3.0 in operating systems, set the extensible host controller interface (xHCI) XHCI Hand-off option to enabled. Access this setting from the BIOS setup screen, select the Advanced tab, then select USB Configuration. If the BIOS must support USB 2.0 devices—legacy USB devices—leave Legacy USB Support set to enabled, shown below.
Figure 16. PXE and HTTP boot support Network interface configuration VEP4600 has two 10GbE small form-factor pluggable plus (SPF+) ports, four Gigabit ports, and one Gigabit management port. The BIOS uses these ports for PXE boot. You can configure the wake on LAN setting. You can also configure the one Gigabit port to auto configure or set to a specific speed.
Advanced power management Access the settings for power management from the BIOS setup screen, then select the Socket Configuration tab. On the Advanced Power Management Configuration screen, select Memory Power & Thermal Configuration. By default, SpeedStep(P states) and Autonomous Core C-State are disabled. The Software controlled T-States option is also disabled by default. Figure 18.
Figure 19. Trusted computing options Embedded DIAGS Embedded DIAGS are available in BIOS 3.41.0.9-18, release and DIAG OS v3.41.3.81-8release. Embedded DIAGS in the BIOS validates and verifies all the system's components are operating nominally. System diagnostics include: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
