Description

The dmi_hpe_rom_info_t structure holds the decoded HP/HPE other ROM information: the redundant system ROM and the OEM ROM image of the server.

The structure is returned by dmi_entity_info for the structures decoded by dmi_hpe_rom_info_spec, of type DMI_TYPE(hpe_rom_info), declared in <opendmi/module/hpe.h>, once the HPE extension module (dmi_hpe_module) is enabled, which it is for HP and HPE servers. It lives as long as the context it has been decoded in.

Fields of the OEM ROM image are absent from the structures of the older servers, and are then nullptr. Fields which the structure leaves out, or which do not apply, are not shown, as the has_ fields tell.

Fields

is_redundant_rom

Whether a redundant ROM is installed.

redundant_rom_version

Version of the redundant ROM, which is its release date. Gen12 onwards reserve the field.

bootblock_version

Version string up to Gen8, whose meaning is not documented. Its dates are earlier than the ones of the ROM, which suggests the boot block. Gen9 onwards reserve the byte.

oem_rom_filename

File name of the OEM ROM image. Firmware which has no image leaves the string out or fills it with blanks, which the decoded string is trimmed of.

oem_rom_date

Build date of the OEM ROM image.

unknown_string

String whose meaning is not established, e.g. 2.9 on a G6 server.

has_redundant_rom_version

Whether redundant_rom_version is shown, which it is when a redundant ROM is installed, up to Gen11.

has_oem_rom

Whether oem_rom_filename and oem_rom_date are shown, which they are when the raw file name is neither empty nor begins with two blanks.

has_unknown_string

Whether the structure holds unknown_string, which the structures shorter than 10 bytes leave out.

Not part of the SMBIOS specification. Defined by HP and HPE for their servers; the layout is the one dmidecode documents.
