Latest Firmware for ASM1064/1166 SATA Controllers

Chip looks tight to get a clamp on as its directly flush to sata connector. The problem with a lot of these chinese flash chips is they tend to smudge the writing so you can’t tell what they are, and when you can read it they source cheap unrecognised parts from noname brands (note the lack of a logo on this 8 pin spi) and sometimes flasher doesn’t like it but attempts to flash anyway and i think this is why sometimes they end up bricked, it definately looks EON 25Q40 based so try that.

You can definately read and write these chinese adapters without it being powered or desoldered, ive done it in another forum to hoover off and hex edit the stock bios for my own backup purposes, but it is very very finicky with the clamp.

The false 32 device enumeration with asm1166 sure needs fixing as a) it doesn’t happen with the older adapters (asm1062) and b) slows things down to a crawl at least on my systems until the drivers are applied. There are patches for linux to work around this flaw but nothing windows based.
