Version 1.09
============

• Added new command line parameter, "/4", which will force a track size of 56 sectors to be reported in geometry requests. This will improve performance for newer HDs with 4K sectors and file systems which use block sizes larger than 512 bytes (FAT, JFS, ...) because all partitions will be aligned on 4K (8 sector) boundaries.

• Changed AP_DEVICE parameter to ata_cmd() from 16 bits to 8 bits -- the corresponding field in ATA_CMD has always been 8 bits and there's no point discarding the lower 8 bits of the AP_DEVICE parameter as a general rule. Besides, it confused me in the end...

• Always return some kind of error in ata_req_sense() because this function will only be called when we received an error interrupt; atapi_req_sense() already does this.

• Cosmetic changes
