supported hardware list. Judging by the PCI driver attachment, dpt_pci.c only supports a single adapter rather than the various PCI adapters listed. The list of EISA adapters listed somewhat overlaps with the device IDs in dpt_eisa.c. It's not clear which devices are ISA-only devices.

.Sh NAME
|
|
.Nm dpt
|
|
.Nd DPT RAID Controller SCSI driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device scbus"
|
|
.Cd "device dpt"
|
|
.Pp
|
|
For one or more EISA cards:
|
|
.Cd "device eisa"
|
|
.Pp
|
|
For one or more PCI cards:
|
|
.Cd "device pci"
|
|
.Pp
|
|
To allow PCI adapters to use memory mapped I/O if enabled:
|
|
.Cd options DPT_ALLOW_MEMIO
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
dpt_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports DPT RAID SCSI controllers.
|
|
.Pp
|
|
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.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver provides support for the following RAID adapters:
