- STnn indicates Seagate ST412/ST506 compatible
- 3« indicates 3.5 inch half height drive
- 5¬ indicates 5.25 inch half height drive
- FH indicates Full Height 5.25 inch drive
- 'u' in filesize indicates unformatted spec
- formatted capacity is related to BIOS and may vary with different
BIOS and OEM versions
- read/write heads should normally never touch hard disk media
- standard AT hard disk controllers do not use DMA for disk I/O due
to the slow speed of the 8 Bit DMA chips used; Port I/O is used
instead for an actual increase in performance
- with some XT and ESDI systems it is necessary to use debug to
execute the ROM disk format code; The usual method is to set
AH=Drive, AL=Interleave and jump to the code at C800:5 via the
G =C800:5 command (some systems locate this code at C600:5, CA00:5
and CC00:5)
- DOS version and disk size determine cluster size; DOS 2.x always
has cluster size of 8K, while DOS 3.x+ has variable cluster sizes:
2 - 16 Mb partitions have a cluster size of 8K
16 - 128 Mb partitions have a cluster size of 2K
128 - 256 Mb partitions have a cluster size of 4K
256 - 512 Mb partitions have a cluster size of 8K
