+SmartRAID (PM3???) are "Enterprise" class cards,
+and SmartCache (PM2???) cards are in the "Workstation" class.
+The Gen 4 Smart Cache IV products were a re-issue of the Gen 3 utilizing
+upgraded (and cheaper to produce) silicon.
+The PM3334 (Smart RAID III) was not revamped as there was no upgraded silicon
+(68040 processor) and it was using the best DPT made.
+Note there has been customer confusion over the faster enterprise class card
+supported by this driver being an older generation.
+The Gen5 cards are supported by the
+.Xr asr 4
+driver.
