WD Charger ROM fault / Encrypted data with donor ROM.

[fzabkar]

I confirmed that all the ROYL modules in SA module 0x129 are byte-for-byte equivalent to those modules which I extracted from the ROM. The only minor difference is the SA location of module 0x01 in module 0x20B.

Also, if I strip the leading 0x200 bytes from SA module 0x109, it compares byte-for-byte with the first half of the ROM until the end of the code section.

There are a number of very similar posts on the pc3K forum, although having numerous talents I don't think fzabkar is clairvoyant and will need the rom to check it
