Well, the USB format idea was left unimplemented as we (I) couldn't get it working, but we should probably take a look at makebootfat to achieve the same goals.

Or just use parted instead of fdisk to wipe the MBR and create it from scratch. It does the right thing on the USB sticks I tried.


Note that the Syslinux tool "mkdiskimage" can be used to create disk images (or disk) with arbitrary geometry.

...which is an important part of the puzzle, and the one that have been discussed the most in this thread.

However, please note that "the right thing" regarding partition table IS NOT ENOUGH for all BIOSes to recognize the USB stick as a bootable device!

makebootfat not only formats with disk geometry that *is* right, but also use a handcrafted MBR which has a higher chance of *looking* right by various BIOSes - both when looking for USB-FDD, USB-ZIP and USB-HDD.
