The KBL Param buffer (temporary name was sysroot buffer) is a <code>0x100 or 0x200</code> bytes sized buffer passed to the Secure Kernel BootLoader in the scratch space and contains all sorts of flags and system parameters.

This buffer is created in [[Second Loader]] copied to [[Secure Kernel]], passed to the Secure and Non-Secure Kernel BootLoaders, and finally to the non-secure kernel. It is used in many functions to check for features that are enabled for the system. The strategy in this buffer is to compute once for all the information that is often used, to share it between all security layers not to have to implement generator code many times, and to implement the generation code in the most secure layer: second_loader (excluding first_loader but that's because first_loader is not updatable and has minimum code). | ||

The KBL Param buffer (temporary name was sysroot buffer) is a 0x100 or 0x200
bytes sized buffer passed to the Secure Kernel BootLoader in the scratch space and contains all sorts of flags and system parameters. This buffer is created in Second Loader copied to Secure Kernel, passed to the Secure and Non-Secure Kernel BootLoaders, and finally to the non-secure kernel. It is used in many functions to check for features that are enabled for the system. The strategy in this buffer is to compute once for all the information that is often used, to share it between all security layers not to have to implement generator code many times, and to implement the generation code in the most secure layer: second_loader (excluding first_loader but that's because first_loader is not updatable and has minimum code).

QA flags
The steps to install QA flags on a PS Vita are:
Write Qaf token to NVS at offset 0x400 (0x80-bytes) (tied to Console ID). Write Qaf token RSA signature to NVS at offset 0x5A0 (0x100-bytes) (only required on firmware 1.80 and above). Write Qaf version to SNVS sector 0x15. Clear Qaf inhibit DIP switches 240 and 241 (maybe even more DIP switches inhibit QA flags). Write Qaf enable flag to NVS at offset 0x480. Set Qaf ON flag to SNVS mgmt sector.
The following libraries are available for checking QA Flags
In the following table bytes are counted from left to right and bits from left to right too (little-endian). However the OS uses bit masking for QA flags (unlike bit shifting for DIP Switches).

Boot flags
These Boot flags come from Ernie NVS.
On FW 3.60, second_loader generates the boot flags as following:
- byte 0 = read from NVS 0x4A0
- byte 1 = read from NVS 0x481
- byte 2 = zeroed
- byte 3 = read from NVS 0x483
- byte 4 = read from NVS 0x487
- byte 5 = read from NVS 0x486
- bytes 6-0xF = zeroed
Example: FF FF 00 FF FF FF 00 00 00 00 00 00 00 00 00 00
DIP Switches
DIP switches area embeds two parts: Communication Processor information as 32-bit integers, followed by DIP switches stored as bit flags.
Offset | Size | Description |
---|---|---|
0x40 | 0x4 | CP Timestamp 1 (ex: 0x4AD86AB3 -> 16/10/2009 14:44:35) |
0x44 | 0x2 | CP Version (ex: 0x1301 -> 1301 on PDEL-100x) |
0x46 | 0x2 | CP Board ID (3 on DEM-300xH, 4 on PDEL-100x) |
0x48 | 0x4 | CP Timestamp 2 (identical as CP Timestamp 1) |
0x4C | 0x4 | ASLR Seed (?USER flags?) (also set on CEX and DEX) (ex: 0x00000000 on a DEM-300xH) |
0x50 | 0x4 | SDK (SCE) flags (ex: 0x80000000, 0x80000001, 0x80000003, 0x81000000, 0x81000001, 0, 2) |
0x54 | 0x4 | Shell flags (ex: 0x00000000 on a DEM-300xH) |
0x58 | 0x4 | Debug control flags (ex: 0x000413E7 on a DEM-300xH, 0x001453E7 dev mode, 0x00080002 release mode) |
0x5C | 0x4 | System control flags (ex: 0x2000001C on a DEM-300xH, 0x20000010 dev mode, 0x20000000 release mode) |
DIP Switches bit flags resolving
Warning: DIP Switches bit flags actually start at offset 0x10 (before that is CP information), which implies the first bit flag number is 128 (bit_num = offset / 8).
DIP Switches bit flags follow little-endian logic, which makes it hard to visualize in commonly used big-endian hexadecimal:
- ((uint32_t *)kbl_param->dipsw[0x10])[0] = 0x00000001 (big-endian in hex) = 01 00 00 00 (little-endian in hex) = 10000000 00000000 00000000 00000000 (little-endian in base 2) <- the 1 corresponds to bit flag number 128
- ((uint32_t *)kbl_param->dipsw[0x10])[0] = 0x00000002 (big-endian in hex) = 02 00 00 00 (little-endian in hex) = 01000000 00000000 00000000 00000000 (little-endian in base 2) <- the 1 corresponds to bit flag number 129
- ((uint32_t *)kbl_param->dipsw[0x10])[0] = 0x00000100 (big-endian in hex) = 00 01 00 00 (little-endian in hex) = 00000000 10000000 00000000 00000000 (little-endian in base 2) <- the 1 corresponds to bit flag number 136
- ((uint32_t *)kbl_param->dipsw[0x10])[0] = 0x80000000 (big-endian in hex) = 00 00 00 80 (little-endian in hex) = 00000000 00000000 00000000 00000001 (little-endian in base 2) <- the 1 corresponds to bit flag number 159
As you can see this way is not convenient to know in memory on which byte corresponds which bit flag, so instead we can use a formula to convert bit number to offset and bit: offset = (bit_num / 32) * 4
, bit = bit_num & 31
. This is used for example in the following code:
SceBool sceKernelCheckDipswForDriver(SceUInt32 no) { return (*(SceUInt32 *)(kbl_param->dipsw + (no >> 5) * 4) >> (no & 31)) & 1; }
CP Information
Bits 0-31
is a 32-bit integer of the current time on the CP clock. This is duplicated in bits 64-95
.
Bits 32-47
is a 16-bit integer of the CP version and bits 48-63
is a 16-bit integer of the CP board ID. All integers are little-endian. On units that do not have a CP, these fields are zeroes.
Bits 96-127
is 32-bit integer ASLR seed that is randomized on each boot in second loader. It can be disabled by setting a specific DIP switch or QA flag byte 0xE mask 1.
Bits 0-63
are also manipulable as general purpose DIP Switches exposed with sceKernelSetDipsw
, sceKernelClearDipsw
, and sceKernelCheckDipsw
but these functions do not change anything in hardware (only cached values are overwritten in SceSysmem).
According to SDK only DIP Switches 0-63 are accessible from usermode, however:
- On FW 0.990 (but not on FW 0.931 nor 3.60), DIP Switch number 237 is the only one out of range 0-63 that can be set from usermode.
- Usermode SELFs can use DIP Switches number > 63 if they have a special attribute or capability in SELF Auth Info.

Bytes meaning
As PS Vita uses little-endian, we describe here in the same order, from the lowest to the highest.
First byte
This byte indicates the presence of some components. It works by bit flags:
- 0x01: ?has SD card reader? (some DevKits and prototypes)
- 0x02: has WWAN (3G modem). This is what SceBbmc checks to know if 3G modem is supported.
- 0x04: unknown
- 0x08: ?has microUSB? (Slim only)
- 0x10: is MC emu capable (Slim and PS TV only). MC Emulation is done by partitionning the internal memory EMMC.
- 0x20: has hw_info_2 (Slim and PS TV only)
- 0x40: is Show mode
- 0x80: is IDU mode
Second byte
This byte indicates the motherboard minor version. It is relative to the motherboard main version which is indicated by third byte.
Third byte
This byte indicates the motherboard main version:
- 10 -> unknown prototype motherboard, has Syscon, maybe IRS-001
- 31 -> IRT-001
- 40 -> IRS-002
- 41 -> IRT-002
- 51 -> PS TV prototype motherboard
- 60 -> IRS-1001
- 70 -> DOL-1001
- 72 -> DOL-1002
- 80 -> USS-1001
- 82 -> USS-1002
- 90 -> unknown prototype motherboard
We can also guess that flag 1 means that the console has a Communication Processor.
Fourth byte
This byte is reserved in case 3 bytes becomes not enough to handle all Hardware Info:
- 00 -> default, unused
Power Info
Experimental point of view
- No AC connected + No POWER Button pressed: 0x0
ex: rebooting by software PS Vita when AC is not connected
- No AC connected + POWER Button pressed: 0x4
ex: booting PS Vita by pressing POWER button when AC is not connected
- AC connected + No POWER Button pressed: 0x8
ex: rebooting by software PS Vita when AC is connected
ex: autobooting PS TV/IDU PS Vita by pluging AC
- AC connected + POWER Button pressed: 0xC
ex: powering off by software PS TV then booting it by pressing POWER button
ex: booting PS Vita by pressing POWER button when AC is connected
Bit flags point of view
Bit | Description |
---|---|
0 | unknown. Not seen. |
1 | unknown. Not seen. |
2 | POWER button: pressed: 1 - not pressed: 0 |
3 | AC: connected: 1 - disconnected: 0 (note that PS TV always has AC connected) |
Hardware Info 2
Hardware Info 2 is supported since System Software version 2.10. It is an extension to Hardware Info
Hardware Info 2 is got from Syscon command 6.
It can be obtained using SceSyscon#sceSysconGetHardwareInfo2ForDriver.
Bit | Description |
