[4.0.0+] This item is obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Icosa), 1 (Copper), 2 (Hoag), 3 (Mariko) or 4 (Invalid).
[7.0.0+] This item can be obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]], but is now only 0 (Icosa) or 0xF (Invalid) in retail units.
[7.0.0+] This item no longer depends on fuses and can only be 0 (Icosa) or 0xF (Invalid) in retail units.
[8.0.0+] This item can be obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be:
* 0 ('''Icosa'''; Erista retail and EDEV), if development flag (bit 8) is '''Retail''' and production flag (bit 2) is '''Production'''.
* 1 ('''Copper'''; Erista SDEV), if development flag (bit 8) is '''Development''' and production flag (bit 2) is '''Prototype'''.
* 2 ('''Hoag'''; Mariko Lite retail and HDEV), if new hardware type (bits 16-19) is '''Hoag'''.
* 3 ('''Iowa'''; Mariko retail and EDEV), if new hardware type (bits 16-19) is '''Iowa'''.
* 4 ('''Calcio''').
* 5 (Invalid).
It is still only 0 (Icosa) or 0xF (Invalid) in retail units.
