Field Documentation

A 64-bit signature that identifies the type of table that follows.

Unique signatures have been generated for the EFI System Table, the EFI Boot Services Table, and the EFI Runtime Services Table.

Definition at line 137 of file UefiMultiPhase.h.

The revision of the EFI Specification to which this table conforms.

The upper 16 bits of this field contain the major revision value, and the lower 16 bits contain the minor revision value. The minor revision values are limited to the range of 00..99.

Definition at line 144 of file UefiMultiPhase.h.

The size, in bytes, of the entire table including the EFI_TABLE_HEADER.

Definition at line 148 of file UefiMultiPhase.h.

The 32-bit CRC for the entire table.

This value is computed by setting this field to 0, and computing the 32-bit CRC for HeaderSize bytes.

Definition at line 153 of file UefiMultiPhase.h.

Reserved field that must be set to 0.
