* non-Linux driver. Mark Salyzyn and Bob Pasteur consulted on the original
|
| 26 |
|
|
* driver.

|
|
* NOTES:
|
| 73 |
|
|
* The DPT card optimizes the order of processing commands. Consequently,
|
| 74 |
|
|
* a command may take up to 6 minutes to complete after it has been sent
|
| 75 |
|
|
* to the board.
|
| 76 |
|
|
*
|
| 77 |
|
|
* The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the
|
| 78 |
|
|
* interface files for Adaptec's management routines. These define the structures used
|
| 79 |
|
|
* in the ioctls. They are written to be portable. They are hard to read, but I need
|
| 80 |
|
|
* to use them 'as is' or I can miss changes in the interface.
