...nough. When I cloned windows partitions from one pc to another, I sometimes ended with unbootable windows (and simple hexedit /dev/whateverN to adjust values of heads and sectors-per-track fixed the issue). Anyway, I was thinking about extending chain.c32 code a bit to do following when "sethidden" option is specified (or better add extra options - such as "setgeometry", "setdrive" and "setbpb" (equivalent of all options specified) - to keep it more flexible): - update hidden sectors field (as it does currently) - at 0x1C - update sectors-per-track and h...

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates
