Identify Your Wii DVD Chip Using the Wii Serial#

Over here is a table which should make it easy to see if your Wii uses the D2B Chipset which is incompatible to current Wii modchips.

Mine uses the old compatible one (Serial# LEH 106XXXXX)

Europe

GC2 – DMS or GC2R – D2A (Compatible with first generation mod chips)
- LEH 100XXXXX
- LEH 101XXXXX
- LEH 102XXXXX
- LEH 103XXXXX
- LEH 104XXXXX
- LEH 105XXXXX
- LEH 106XXXXX
- LEH 107XXXXX
- LEH 108XXXXX
- LEH 1091XXXX

GC2R – D2B (Incompatible with first generation mod chips)
- LEH 109225XX
- LEH 1100XXXX
- LEH 1104XXXX

For European models it seems the D2B chip was introduced somewhere between LEH 1091XXXX and LEH 109225XX.

North America

GC2 – DMS or GC2R – D2A (Compatible with first generation mod chips)
- LU 100XXXXXX
- LU 102XXXXXX
- LU 103XXXXXX
- LU 104XXXXXX
- LU 1050XXXXX

- LU 300XXXXXX
- LU 301XXXXXX
- LU 302XXXXXX
- LU 303XXXXXX
- LU 304XXXXXX
- LU 305XXXXXX
- LU 306XXXXXX

- LU 502XXXXXX
- LU 503XXXXXX
- LU 504XXXXXX
- LU 505XXXXXX
- LU 506XXXXXX
- LU 5074XXXXX

GC2R – D2B (Incompatible with first generation mod chips)
- LU 1047XXXXX
- LU 1054XXXXX

- LU 3072XXXXX

- LU 50853XXXX
- LU 5089XXXXX

For North-America it appears that there are three different ranges in use (LU1/LU3/LU5). Its possible that each range is used in a different area, factory or language pack.
Each range will have a number where the D2B chip is introduced.
For LU1 this seems to be between LU 104XXXXXX and LU 1054XXXXX.
For LU3 its between LU306XXXXXX and LU3072XXXXX and
for LU5 its somewhere between LU 5074XXXXX and LU50853XXXX.
