===== AoE boot firmware table ===== ==== Introduction ==== The AoE Boot Firmware Table (aBFT) is a block of information containing various parameters useful to the AoE boot process. It is the mechanism whereby the boot firmware conveys information about the boot device to the loaded operating system. ==== Location ==== The aBFT can be located by scanning through base memory (address 0x00000 to address 0x09FFFF) for the table header signature. The table must be aligned on a 16-byte boundary, and the checksum must be correct. ==== Conventions ==== All quantities are little-endian. ==== Structure ==== ^ Field ^ Byte Offset ^ Byte Length ^ | Signature | 0 | 4 | | Length | 4 | 4 | | Revision | 8 | 1 | | Checksum | 9 | 1 | | OEMID | 10 | 6 | | OEM Table ID | 16 | 8 | | OEM Revision | 24 | 4 | | Creator ID | 28 | 4 | | Creator Revision | 32 | 4 |
