SYNOPSIS:     Installing the New DPT 2022 EISA controller

OS RELEASE:   

PRODUCT:      Solaris x86

KEYWORDS:     Install configure DPT 2022 EISA controller


DESCRIPTION:

An outline of some the issues and observations relating to the
installation and configuration of the DPT 2022 EISA controller. 


SOLUTION:

This controller is a next generation low-cost replacement for the now
obsoleted DPT-2012 family.  The card is a full length EISA controller
with a reduced chip count.  The cache module now sits on the controller
and takes industry standard 36bit SIMMs rather than taking up a second
slot and needing proprietary memory modules. 

By default the card has Jumper Y20 enabled which means that for those
cards with floppy controllers on them -they will conflict with any other
host based floppy controllers.  BIOS and SmartROM were at level 5C and
2C respectively.  This is important to remember as earlier revisions may
cause a problem especially with most UNIX environments.  If you have an
earlier release of firmware please contact your DPT channel for a BIOS /
SmartROM upgrade.  Finally the controller EISA setup defaults to using
IRQ 15 level interrupts.  For Solaris x86 change this setting to IRQ 15
edge interrupts.  Finally, DPT recommended booting up DOS and running
their dptmgr.exe utility to mark the initial installation as being a
Solaris installation.  No further action is required.  The installation
should proceed normally.
