DPT(4) BSD Kernel Interfaces Manual DPT(4)NAME
dpt -- DPT RAID Controller SCSI driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device dpt
For one or more EISA cards:
device eisa
For one or more PCI cards:
device pci
To allow PCI adapters to use memory mapped I/O if enabled:
options DPT_ALLOW_MEMIO
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
dpt_load="YES"
DESCRIPTION
The dpt driver supports DPT RAID SCSI controllers.
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 asr(4) driver.
HARDWARE
The dpt driver provides support for the following RAID adapters:
o DPT Smart Cache Plus
o Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
o Smart RAID II (PM3?2?, PM3021, PM3222)
o Smart Cache III (PM2?3?)
o Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
o Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
o Smart RAID IV

The dpt driver first appeared in FreeBSD 2.2.6.
AUTHORS
The dpt driver was written by Simon Shapiro and ported to the CAM SCSI system by Justin T. Gibbs.

EISA(4) BSD Kernel Interfaces Manual EISA(4)NAME
eisa -- Introduction to EISA bus machine-independent drivers and support
SYNOPSIS
options EISAVERBOSE
Machine-dependent; depends on the bus topology and EISA bus interface of your system. Typical EISA buses are either connected directly to
the main system bus, or via an PCI to EISA bridge. See the intro(4) documentation for your system for details.
DESCRIPTION
NetBSD includes a machine-independent EISA bus subsystem and several machine-independent EISA device drivers.
Your system may support additional EISA devices. Drivers for EISA devices not listed here are machine-dependent. Consult your system's
intro(4) for additional information.
SUPPORTED DEVICES
NetBSD includes machine-independent EISA drivers, sorted by device type and driver name:
Disk and tape controllers
cac Compaq array controllers.
mlx Mylex DAC960 and DEC SWXCR RAID controllers.
SCSI interfaces
ahb Adaptec 174x SCSI interfaces.
ahc Adaptec AIC 7770, 274x, and 284x SCSI interfaces.
bha BusLogic BT-74x SCSI interfaces.
dpt DPT SmartCache/SmartRAID III and IV SCSI interfaces.
uha Ultrastor 24f SCSI interfaces.
Network interfaces
ep 3Com 3c579 and 3c592 10Mbit Ethernet, and 3c597 10/100Mbit Ethernet interfaces.
fea Digital DEFEA FDDI interfaces.
le Digital DE422 Ethernet interfaces.
tlp Digital DE425 Ethernet interfaces.
Note that most or all EISA devices also have PCI or ISA equivalents. These are listed in pci(4), isa(4), or isapnp(4), respectively. The
manual pages for each individual driver also lists the supported bus variants.
SEE ALSO ahb(4), ahc(4), bha(4), cac(4), dpt(4), ep(4), fea(4), intro(4), le(4), mlx(4), tlp(4), uha(4)HISTORY
The machine-independent EISA subsystem appeared in NetBSD 1.2.

Hi,
a friend of mine gave me an old HP B180 Unix Workstation with HPUX, the only problem with that, the onboard graphicsbaord doesn´t work anymore. I want to buy a new PCI Graphicsboard (350RAMDAC), but they only have Linux drivers going with the card.
Question: Is it possible to compile... (4 Replies)
Hi!
I just wanted to know what network cards are supported in FreeBSD. I have looked at the list of supported cards but I can't find any of them in the stores. Is the list not updated, I would really preciate info about where (in EU, Sweden) I can buy them.

Hi,
Can X6799A PCI single fiber channel cards be fitted into the top 2 slots of a Sunfire v880. These 2 slots are 66Mhz and X6799A are supposed to be able to connect at this speed.
However , I believe the cards are 5volts , whilst the slots are 3.3volts. (2 Replies)
Hi
I am currently looking for a BTLD for an VERY old DPT PM2044UW RAID Controller to be used on a Sco Openserver 5.0.4 installtion. Have searched the net and can not find one.
Anyone out there know where I can download this from? (3 Replies)
I seem to be having a driver issue installing a PCI SCSI card. Any ideas where I can track these down.. I can't seem to find them on the OS install disk. I'm using AIX 5.3.

I got a old server that came from another company and nobody knows root password.
Server is SCO OpenServer 5.0.5

Hello,
I have a few questions about this server.
It has two CPU's 3.20 ghz / 800 mhz / 1MB L2
5120 MB RAM
6 hard disks on HP Smart Array 6i controller (36.4 GB Ultra320 SCSI HD each)
RAID set to RAID 5 (5 discs) with one spare (6th disk)
USB, 2 Ethernet ports, 1 ILO port, 1 SCSI port

Hi !
I've been given a T5240 with 4 disks and 2 HBA cards (but no array connected). I did a factory reset on SP and NVRAM clean on OBP because the server had been used before.
I boot cdrom in single mode and try to create a hw mirror with disks from c1... but only c2 is seen by raidctl.

I had instructions on linking 2 smart cards to one user, Does anyone remember any website on this or have instructions I lost mine :( it was basically used for leaving one card at work and one at home so they can use both to pull up same session. (1 Reply)
