31 .Nd DPT RAID Controller SCSI driver
33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
40 For one or more EISA cards:
43 For one or more ISA cards:
46 For one or more PCI cards:
49 To allow PCI adapters to use memory mapped I/O if enabled:
50 .Cd options DPT_ALLOW_MEMIO
53 Alternatively, to load the driver as a
54 module at boot time, place the following line in
56 .Bd -literal -offset indent
62 driver supports DPT RAID SCSI controllers.
64 SmartRAID (PM3???) are "Enterprise" class cards,
65 and SmartCache (PM2???) cards are in the "Workstation" class.
66 The Gen 4 Smart Cache IV products were a re-issue of the Gen 3 utilizing
67 upgraded (and cheaper to produce) silicon.
68 The PM3334 (Smart RAID III) was not revamped as there was no upgraded silicon
69 (68040 processor) and it was using the best DPT made.
70 Note there has been customer confusion over the faster enterprise class card
71 supported by this driver being an older generation.
72 The Gen5 cards are supported by the
78 driver provides support for the following RAID adapters:
84 Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
86 Smart RAID II (PM3?2?, PM3021, PM3222)
88 Smart Cache III (PM2?3?)
90 Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
92 Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
