Z840 Host PC BIOS Setup

Prerequisites

Table 3. Safety

danger

ELECTROCUTION HAZARD
Disconnect AC power from the Host PC before reseating or replacing components because there is power to the system board even when the Host PC is powered down.
USE PROPER LOCKOUT / TAGOUT PROCEDURES BEFORE REPLACING THE COMPONENTS.

notice

Do not turn the Host PC power off while the ROM is saving your BIOS Setup (F10) Utility changes or when flashing new BIOS ROM Code, because the CMOS could become corrupted. After you exit the F10 Setup screen, it is safe to remove all power from the Host PC.

Overview

The BIOS of the computer is a collection of machine language programs stored as firmware in ROM. The BIOS ROM includes such functions as POST, PCI device initialization, Plug 'n Play support, power management activities, and the BIOS Setup (F10) Utility. The BIOS Setup (F10) Utility enables you to change factory default settings and set or change the system configuration based on the Host PC hardware or system functionality requirements.

1 HP Z840 BIOS Flashing and Recovery

The following information covers the necessary procedures for flashing and recovering from corrupted or incomplete flashing of the Host PC’s BIOS ROM. This is not to be confused with the BIOS Settings discussed later. The BIOS firmware code flashed to the BIOS ROM is the executable portion of the BIOS ROM code, which includes a default set of configuration settings. Later, customize these settings for the Host PC’s specific configuration details. You can save and restore these customized settings on CD for quick restoration in the event of BIOS ROM corruption or BIOS updating.

1.1 Z840 BIOS ROM Flash Update Procedure

Procedure

Power down the Host PC.
Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP DriveKey.
Power on the Host PC.
When the display is active and Press the Esc Key for Startup Menu appears at the bottom of the screen, press F10 or Esc.
The Startup Menu appears, use the up and down arrow keys to select BIOS Setup.

Figure 1. Startup Menu
In the Computer Setup (F10) Utility menu, the following headings are displayed: Main, Security, Advanced and UEFI Drivers.
Use the left and right arrow keys to select Main, use the up and down arrow keys to select Update System BIOS, and then press Enter. (See Figure 2.)

Figure 2. Flash System BIOS ROM Selection
If no BIOS image CD or USB media is found, you are prompted to insert one and restart the computer.

Figure 3. no BIOS Image CD or USB Media

If a BIOS image CD or USB media is found, the following screen appears.

note: Current BIOS version is BIOS 2.23, below figures are examples.

Figure 4. System BIOS Available (Example)
Select the Update Bios – x.xx, the update procedure is going.

Figure 5. Updating BIOS (Example)
When the System BIOS update is completed, the “Upon restarting, the screen may be blank for a few minutes and various LED lights may flash. Please do not attempt to interrupt or power during this time.” appears. Click Reboot to restart the Host PC.

1.2 FailSafe Boot Block

The FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM flash failure. For example, if a power failure occurs during a ROM upgrade, Boot Block uses a flash-protected section of the ROM to verify a valid system ROM flash when power is restored to the computer.

If the system ROM is valid, the computer starts normally. If the system ROM fails the validation check, FailSafe Boot Block provides enough support to start the computer from a BIOS image CD that has been created from a SoftPaq. The BIOS image CD programs the system ROM with a valid image.
If the system ROM is invalid, the computer power LED blinks red eight times and the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot Block recovery mode message appears.

In preparation for system recovery, use the BIOS CD media file in the SoftPaq to create a BIOS image CD or USB flash drive.

Recovering the Computer from Boot Block Recovery Mode

Procedure

Remove any media such as USB flash drives or discs in the optical drives.
Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP DriveKey.
Turn the computer off, and then turn it on.

If no BIOS image CD or USB media is found, you are prompted to insert one and restart the computer. (See Figure 3)

If a setup password has been established, the Caps Lock light turns on and you are prompted for the password.
Enter the setup password.

If the computer starts from the boot media and successfully reprograms the ROM, three keyboard lights turn on and a rising-tone series of beeps signals successful recover.
Remove the boot media and turn off the computer.
Restart the computer.

2 Z840 BIOS Setup (F10) Utility Functions
