Technical white paper | HP Z840 Workstation

New UEFI BIOS and features/

legacy support

This section describes the new features of the HP rmware (BIOS) installed on

the HP Z840 Workstation. Additional information is available in the Maintenance

and Service Guide for this workstation.

New BIOS core

The HP Z440, Z640, and Z840 Workstations all share the same BIOS image, for which the family name is M60. The M60

BIOS is the rst to use a new common core that will be shared with HP Commercial Desktops and Notebooks.

Compatibility

The M60 BIOS implements UEFI 2.4, Platform Initialization (PI) 1.3, ACPI 5.0, and SMBIOS 3.0.

The M60 BIOS is capable of running both UEFI and legacy operating systems (what the UEFI Forum calls “class 2

rmware”), without reconguration to switch from one to the other. However, when Secure Boot is enabled, only UEFI

operating systems that comply with Secure Boot can be launched.

New BIOS tools

The new BIOS core will require the following new tools:

• UeBiosCong.e – Captures/sets BIOS features from the EFI shell (replaces Repsetup.exe)

• Hp-repsetup – Captures/sets BIOS features from Linux

• HPBIOSUPDREC.exe – Updates BIOS from Windows

• hp-ash – Updates BIOS from Linux

• CustomLogoApp.e – EFI custom logo tool

The tools will be available via SoftPaqs from hp.com under the HP Z840 Workstation support page.
