Program Vender Id

Temp name was Vendor ID. Official name is program_vender_id.

PS3

In geohot's makeself it was used as: set_u32(&(output_self_info_header.i_magic), 0x01000002);.

Not directly related to Authority ID, but for PS3, it seems to have many similarities with it (program_vender_id = 2nd-9th bytes of program_authority_id). It seems also related to SM ; LPAR's and their order suggests hierarchy/permission from high (can do everything) to low (lesser abilities).

program_vender_id	Count	File type
0x00000000	?	lv0 / lv1 only before SDK 060
0x33000077	?	*ldr / lv0 / lv1 only on SDK 060
0xFF000000	16	lv1.self's
0x07000001	180	iso spu self's
0x05000002	17	lv2_kernel.self's
0x02000003	45	ps2_emu self's
0x01000002	6147	CoreOs / dev_flash files / Games

PS Vita and PS4

On PS Vita and PS4 the Program Vender Id area is always zeroed so this section has maybe been replaced by padding.

Structure

typedef struct program_vender_id {
  uint16_t territory;
  uint16_t guest_os_id;
} program_vender_id;

Note: first byte is territory value, last byte is guest_os_id. ?because of endianness that struct would be wrong then?

Territory

To document.

Guest OS ID

0x0000	None
0x0001	PME
