  29. .Sh NAME
  30. .Nm dpt
  31. .Nd DPT RAID Controller SCSI driver
  32. .Sh SYNOPSIS
  33. To compile this driver into the kernel,
  34. place the following lines in your
  35. kernel configuration file:
  36. .Bd -ragged -offset indent
  37. .Cd "device scbus"
  38. .Cd "device dpt"
  39. .Pp
  40. For one or more EISA cards:
  41. .Cd "device eisa"
  42. .Pp
  43. For one or more ISA cards:
  44. .Cd "device isa"
  45. .Pp
  46. For one or more PCI cards:
  47. .Cd "device pci"
  48. .Pp
  49. To allow PCI adapters to use memory mapped I/O if enabled:
  50. .Cd options DPT_ALLOW_MEMIO
  51. .Ed
  52. .Pp
  53. Alternatively, to load the driver as a
  54. module at boot time, place the following line in
  55. .Xr loader.conf 5 :
  56. .Bd -literal -offset indent
  57. dpt_load="YES"
  58. .Ed
  59. .Sh DESCRIPTION
  60. The
  61. .Nm
  62. driver supports DPT RAID SCSI controllers.
  63. .Pp
  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
  73. .Xr asr 4
  74. driver.
  75. .Sh HARDWARE
  76. The
  77. .Nm
  78. driver provides support for the following RAID adapters:
  79. .Pp
  80. .Bl -bullet -compact
  81. .It
  82. DPT Smart Cache Plus
  83. .It
  84. Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
  85. .It
  86. Smart RAID II (PM3?2?, PM3021, PM3222)
  87. .It
  88. Smart Cache III (PM2?3?)
  89. .It
  90. Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
  91. .It
  92. Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
