7.0 (4th August, 2005)
- Updated driver to use SCSI transport class infrastructure
- Upported sequencer and core fixes from last adaptec released
version of the driver.
6.2.36 (June 3rd, 2003)
- Correct code that disables PCI parity error checking.
- Correct and simplify handling of the ignore wide residue
