31 Revision History:
32
33 The skeleton was taken from standard ATAPI.SYS from NT4 DDK by
34 Mike Glass (MGlass)
35 Chuck Park (ChuckP)
36
37 Some parts of code were taken from FreeBSD 4.3-6.1 ATA driver by
38 Søren Schmidt, Copyright (c) 1998-2007
39
40 All parts of code are greatly changed/updated by
41 Alter, Copyright (c) 2002-2007:
42
43 1. Internal command queueing/reordering
44 2. Drive identification
45 3. Support for 2 _independent_ channels in a single PCI device
46 4. Smart host<->drive transfer rate slowdown (for bad cable)
47 5. W2k support (binary compatibility)
48 6. HDD hot swap under NT4
49 7. XP support (binary compatibility)
50 8. Serial ATA (SATA/SATA2) support
51 9. NT 3.51 support (binary compatibility)
52
53 etc. (See todo.txt)
