The sequencer firmware file has both a string (currently showing V17/10c6) and a number (currently set to 1.1). It has become apparent that Adaptec may issue sequencer firmware in the future which could be incompatible with the current driver. Therefore, the driver will be tied to the particular major number of the firmware (i.e. the current driver will load any 1.x firmware). Additionally, the driver will print out both the ascii string and the major number, so with this pach the current firmware will print out aic94xx: Found sequencer firmware version 1.1 (V17/10c6) Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
