Well, if sector size can't be set to 1024k then the game's over. I still haven't found the non-standard FAT - I'm looking for FF FF FF (drive size) and 02 00 (sector size) strings near the beginning of the 8GB disk image.

The sector size here is the hardware sector size, the firmware doesn't get to vote. It is fixed at 512 bytes. Sadly, following a discussion with local pesto fanciers, it turns out that all through the code it uses 24-bit integers for sector counts. (Expanding that to 48-bit integers was a task we put off until we needed it: Carbon is so incredibly tight on memory that those extra three bytes everywhere would have caused us real work in shrinking some other part of the system.)

So it's game over, I'm afraid. Carbon supports up to 2^24 sectors (8Gbytes) only.
