The original linux driver was ported to Linux by Karen White while at |
|
Dell Computer. It was ported from Bob Pasteur's (of DPT) original |
|
non-Linux driver. Mark Salyzyn and Bob Pasteur consulted on the original |
|
driver. |
|
|
|
2.0 version of the driver by Deanna Bonds and Mark Salyzyn. |

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