DPT host adapter device driver
dptr is the device driver for
the entire line of DPT host adapter cards.
It includes multi-channel, wide SCSI,
and PCI support, and supports all
SmartCache III, SmartCache Plus, and SmartRAID products.
For technical support, upgrades, purchases, or product information,
contact DPT at (407) 830-5522 in the US.
A curses version of Storage Manager is
available for the SCO OpenServer system that allows you to
configure and monitor your RAID system.
Obtain this directly from DPT.
If you want to install the SCO OpenServer system, you must
create the RAID system first by running Storage
Manager for DOS.
Once you have configured your RAID
system using Storage Manager, you can add RAID to
an existing system or install RAID on a new system using
the dptr driver.

or contact your system supplier.
Configuring the dptr driver
You can configure the dptr driver using entries in
/etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/dptr.
Changes to these files
take effect once you relink the kernel using
and reboot the system.
Configure dptr driver-specific characteristics
by editing the /etc/conf/pack.d/dptr/space.c file.

parameters to override
the default hardware configuration information.
Of special interest are the adapter= parameter
that specifies information for
the host adapter card
that plugs into or is part of the motherboard,
and the periph= parameter
that specifies information about the host adapter
being used by one of the generic peripheral interfaces
(Sdsk, Srom, or Stp).
The dptr driver supports the dptr.isa=1
bootstring, which enables ISA support for DPT SCSI
devices. This support has been disabled in some operating system
