HP Server ROM
HP ROM (Read Only Memory) is now digitally signed using HP's Corporate Signing Service. This signature is
verified before the flash process starts, reducing accidental programming and preventing malicious efforts
to corrupt system ROM.
HP ROM provides for essential initialization and validation of hardware components before control is
passed to the customer-installed operating system. The ROM also provides the capability of booting from
various fixed media (HDD, CD-ROM) and removable media (USB), to continue operation to the operating
system.
HP ROM performs very early configuration of the video controller, to allow monitoring of initialization
progress via an attached monitor. If configuration or hardware errors are discovered during this early
phase of hardware initialization, suitable messages are now displayed on the connected monitor.
Additionally, these configuration or hardware errors are logged to the Integrated Management Log (IML) to
assist in diagnosis.
HP's ProLiant ROM is used to configure the following:
Processor and chipset status registers
System memory, memory map, and memory initialization
System hardware configuration (Integrated PCI devices and optional PCIe cards).
Customer-specific BIOS configuration (using the HP ROM-Based Setup Utility (RBSU).
