Vital Statistics

|
---
|
|
|
|
PC-DOS 1.10 was released in May, 1982 on one single-sided (160Kb) diskette. A complete listing of all the files
|
|
is shown below. Note that IBMBIO.COM and IBMDOS.COM were marked as *hidden* and *system*, so they are not displayed
|
|
by DIR; their sizes and dates have been determined by inspecting the root directory.
|
|
|
|
Also, in case you're wondering why 1920 + 6400 does not equal the "8704 bytes in 2 hidden files" reported by CHKDSK,
|
|
that's because all CHKDSK byte totals are cluster-granular. On a 160Kb diskette, 1 cluster equals 1 sector or 512
|
|
bytes.
|
|
|
|
CHKDSK considers the size of IBMBIO.COM to be 2048 bytes (1920 rounded up to the nearest 512 multiple), and the
|
|
size of IBMDOS.COM is 6656, so the total number of bytes consumed by those two files is 8704.
