31 .Nd DPT RAID Controller SCSI driver
33 For one or more EISA Controllers
37 For one or more PCI Controllers
41 To allow PCI adapters to use memory mapped I/O if enabled:
42 .Cd options DPT_ALLOW_MEMIO
46 driver supports DPT RAID SCSI controllers.
48 SmartRAID (PM3???) are "Enterprise" class cards,
49 and SmartCache (PM2???) cards are in the "Workstation" class.
50 The Gen 4 Smart Cache IV products were a re-issue of the Gen 3 utilizing
51 upgraded (and cheaper to produce) silicon.
52 The PM3334 (Smart RAID III) was not revamped as there was no upgraded silicon
53 (68040 processor) and it was using the best DPT made.
54 Note there has been customer confusion over the faster enterprise class card
55 supported by this driver being an older generation.
56 The Gen5 cards are supported by the
62 driver provides support for the following RAID adapters:
68 Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
70 Smart RAID II (PM3?2?, PM3021, PM3222)
72 Smart Cache III (PM2?3?)
74 Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
76 Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
