We use a software utility to read a BIOS when the password can be recovered from it, for a CF-54 you need a FULL bios backup obtained using a SPI programmer.

Should work, check again content of the chip with verification, check the soldering and positioning of the chip at the motherboard, check surrounding area for knock off components and so on...

Sounds weird, check you didn't program your old dump by mistake. Everything should be fine with my file, I just checked it again.
