New Uefi Bios And Features/Legacy Support - HP Z440 Technical White Paper

Technical white paper | HP Z440 Workstation
New UEFI BIOS and features/
legacy support
This section describes the new features of the HP firmware (BIOS) installed on
the HP Z440 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 first 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
firmware"), without reconfiguration 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:
• UefiBiosConfig.efi – 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-flash – Updates BIOS from Linux
• CustomLogoApp.efi – EFI custom logo tool
The tools will be available via SoftPaqs from hp.com under the HP Z440 Workstation support page.
