Here is ps2ident v0.835 MID with modified database by AKuHAK.

• PS2Ident is an identification tool that allows dumps of a PlayStation 2 console's ROM chips and MECHACON NVRAM to be made.
  It will also gather data from the console, for research purposes.
  It has the following features:
  
  • Dumps ROM chips (BOOT and DVD ROM) as a whole, not according to their contents (rom0, rom1, rom2 and erom)
  • Displays the actual addresses for DEV1 (rom1, rom2 and erom) that are set by the ROM filesystem drivers.
  • Coloured user interface that is easy to use.
  • Supports dumping to memory cards and USB mass storage devices.
  • Supports multi-languages, which include the 8 supported languages by the PS2
  • Gathers data of all known parts of the PS2.
  • Attempts to automatically match the chip/part name with the version number of the part.
  • Supports all PlayStation 2 consoles, including the SCPH-10000 and SCPH-15000, and the PSX (DVR unit).
• 
  Changes from original ps2ident:
  
  • Detected Model ID list changed, now it contains more models, including not confirmed yet:

  ID	Plant

  • Added some confirmed models with mainboard revisions
  • EMCS ID list modified. In fact I am using some assumptions for this list. It seems that before SCPH-390** all models have EMCS ID 00 (Made in Japan). Starting from Dragon series all EMCS ID are known and proven. But for SCPH-390** there are more values possible: 0x00,0x01,0x02,0x03. 0x01 seems China and I made assumption that this is is Foxconn (never seen something else). I also has sticker and ps2ident data from 0x02 SZMT and 0x03 SKZ. 0x18 is unique for DESR DVR, while real manufacturer unknown - I guess it is safe to make assumption for sticker data (S.EMCS) for DESR series.

  Detected Model ID list:
  

  Model ID	Model Name

  ID	Plant
  0x00	Japan
  0x01	FOXC
  0x02	SZMT
  0x03	SKZ
  0x10	S EMCS
  0x18	S EMCS (PSX)
  0x20	FOXC
  0x21	FOXC
  0x30	SZMT
  0x40	S WUXI

• 
  Update 15/07/2019:
  if you own SCPH-5**** (aka Dragon unit) or any DESR-**00 unit (PSX DVR) and ps2ident shows Unknown motherboard then provide:
  1) Whole and readable sticker photo (you can hide middle of your serial if you wish). Also mention color and edition (if known).
  2) PS2Ident generated *_database.bin file
  3) PS2Ident text file (as attachment or just in text form).
  I decided to assume that board revision for Dragon units and PSX DVR units can be definitely retrieved from their stickers.
  GH-023 - H-Chassis
  GH-026 - I-Chassis
  GH-029 - J-Chassis
  XPD-001 - Early DESRs
  XPD-005 - Second DESR Generation
  For other units
  How to provide data: launch ps2ident from usb stick and check what is shown in Model ID section.
  If there is written Unknown you definitely should share your data.
  If there is written Not confirmed you should share your data as well.
  It even if ps2ident shows known Model ID - please check your sticker data - maybe database is incomplete.
  For example if ps2ident shows SCPH-77004a while you have SCPH-77004b please share your data.
  
  1. First of all check screen where Model ID is placed.
     You should press L1 four (4) times after program loads (see screenshot below) until you see screen with Mechacon at top.
     Do not look at screen where Model is located, Model will not be accurate (not very precise).
     If you see Unknown or Not confirmed, you should provide your data.
     If you see some data, you should check if it matches data on the sticker.
     If data on the sticker differs from what program shows - you defietly should provide your data.
     
  2. How to share: in fact the best solution just post here ps2ident log and sticker photo with removed serials.
     Also mention color or revision of your console (for example SCPH-39000 TB or SCPH-50000 NB(b)).
     It is safer to remove serial numbers from image while not necessary.
     Please keep first digit or first 2 digits of your serials - do not remove it completely.
     Also do not hide digits from barcode beginning and barcode middle
     - this data is not personal/unique and potentially can contain useful info.
  3. Provide also *_database.bin file.
     
  4. In case if you want to do more: you opened console,
     checked mainboard revision and want to share mainboard revision.
     In this case also check if some chips are unrecognized.
     Nowadays only some mechacon chips are missing, but who knows maybe you will provide new data.
  
  You can also just post Model ID and exact console model including color, little 'a' or 'b' near model if you wish.
  If you are providing motherboard revisions please also attach *_database.bin file generated by program.
  P.S. Some Model IDs was recovered from NVRAM dumps (of course all not confirmed).
  If you cannot access console but still have NVRAM (or 'bios') dumps of consoles that are not in the list I can add data into Not confirmed section it even if there is no sticker photo (while sticker photo of course will be useful).
  

Help, support, providing motherboard revisions:

The model number can be SCPH-30000, SCPH-30001, 35001, SCPH-30002, 35002, SCPH-30003, 35003, SCPH-30004, 35004 If the marked screw doesn't show up in the expansion bay of your PS2 then please take a look on the bottom of the PS2 case. If there is an electrical hazard warning on the bottom of the case then it is a V4. Kabeladapter, A-KA173389923 (minijack 3,5mm til 5-pins DIN) er inkludert DAB-adapter som inneholder en tuner-del med line out utgang for tilkopling mot eksisterende anlegg, radio, forsterker etc.
