| 51 * "On non-EFI systems, the SMBIOS Entry Point structure, described below, can 52 * be located by application software by searching for the anchor-string on 53 * paragraph (16-byte) boundaries within the physical memory address range 54 * 000F0000h to 000FFFFFh. This entry point encapsulates an intermediate anchor 55 * string that is used by some existing DMI browsers." | 56 * (From System Management BIOS (SMBIOS) Reference Specification, 3.6.0) 57 * 5.2.1 SMBIOS 2.1 (32-bit) Entry Point 58 * 59 * "On non-UEFI systems, the 32-bit SMBIOS Entry Point structure, can be 60 * located by application software by searching for the anchor-string on 61 * paragraph (16-byte) boundaries within the physical memory address 62 * range 000F0000h to 000FFFFFh. This entry point encapsulates an intermediate 63 * anchor string that is used by some existing DMI browsers. 64 * 65 * On UEFI-based systems, the SMBIOS Entry Point structure can be located by 66 * looking in the EFI Configuration Table for the SMBIOS GUID 67 * (SMBIOS_TABLE_GUID, {EB9D2D31-2D88-11D3-9A16-0090273FC14D}) and using the 68 * associated pointer. See section 4.6 of the UEFI Specification for details. 69 * See section 2.3 of the UEFI Specification for how to report the containing 70 * memory type. 71 * 72 * NOTE While the SMBIOS Major and Minor Versions (offsets 06h and 07h) 73 * currently duplicate the information that is present in the SMBIOS BCD 74 * Revision (offset 1Eh), they provide a path for future growth in this 75 * specification. The BCD Revision, for example, provides only a single digit 76 * for each of the major and minor version numbers." 77 * 78 * 5.2.2 SMBIOS 860 3.0 (64-bit) Entry Point 79 * 80 * "On non-UEFI systems, the 64-bit SMBIOS Entry Point structure can be located 81 * by application software by searching for the anchor-string on paragraph 82 * (16-byte) boundaries within the physical memory address range 000F0000h to 83 * 000FFFFFh. 84 * 85 * On UEFI-based systems, the SMBIOS Entry Point structure can be located by 86 * looking in the EFI Configuration Table for the SMBIOS 3.x GUID 87 * (SMBIOS3_TABLE_GUID, {F2FD1544-9794-4A2C-992E-E5BBCF20E394}) and using the 88 * associated pointer.
