Glendon Gross: >Is there anyone interested in rewriting that "fake" partition table, Please look at the thread with the same topic three weeks ago. I stated that it wouldn't be possible because there is a fundamental disagreement: BIOS standard demands that the first *sector* always remains reserved. However DD mode only reserves the first *block* and starts with the actual contents at the second block. This (intentionally) violates BIOS standards. Though many BIOSsen will happily accept it, some will get picky and refuse to boot a DD disk due to standards violation. If you would leave the first *sector* reserved with DD mode, you are basically left with the layout of non-DD mode, so this is pointless. >or is that requirement satisfied by the non-dedicated format? Exactly. Non-DD follows the BIOS standards, so it will serve you fine, at the "expense" of losing some few kB of disk space. >it >would be aesthetically more pleasing to be able to use the >dedicated format. Fully agree. However there are things in the BIOS architecture that don't care about aesthetics. After all, this is the PC world.
