Program Vender Id

For some reason it was named program_vendor_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 seems to have many similarities with it (vendorid = 2nd-9th bytes of authid). It seems also related to SM ; LPAR's and their order suggests hierarchy/permission from high (can do everything) to low (lesser abilities).

VendorID	count	filetype
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

PSVita

On PSVita always 00 00 00 00.

Structure

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

Note: first byte is territory value, last byte is guest_os_id.

Guest OS ID
