	ESTIMATED MAN HOURS	N/A
	CLASS OF CHANGE:	INFORMATIONAL
	REASON FOR CHANGE:	GENERAL INFORMATION ON SERIAL I/O STARGATE CONTROLLERS

This is being released to provide information pertaining to the 10mhz and 20mhz
stargate controllers.

2. The 10mhz stargate (serial i/o) kits are no longer available. The only 10mhz
spares that will be available are through at&t reworked items.

3.         New serial i/o parts have been upgraded to 20mhz and some control code has
            been moved to programmable i/o space. A new software driver is required to
            support the new parts.

5. The flex including the new adf files and dos utilities is now on the windows nt bbs.

6. The diskettes that includes the new adf files as well as the old ones is stocked
under at&t part number, 006-3300873.

7. The 8 port module requires the same amount of memory as the 16 port. For
example, (2) 8 port modules would be set up on the reference disk as:

Note: this can restrict the total number of modules in the micro-channel because
of the 128kb limit on micro-channel memory.

8.1.      it is very important that the person in charge of the installation has thoroughly
            reviewed and understood the general micro channel module information guidelines,
            as presented in sections, '8 port serial controller' and '16 port serial controller', in
            chapter d1 of the at&t 345x/35xx hardware service manual. Additionally, the
            'guidelines for installing modules in the micro channel', 'modules that may be used
            in the secondary micro channel' and 'module configuration parameter summary'
            sections, contain detailed information to successfully install the star gate and/or
            any other host adapter, or controller board in a system 3000.

8.2.     the attached procedure is a basic guide for the installation of the star gate boards
           and it's corresponding tty driver package and it assumes that the system includes
           the 'madf' package installed.

            Note: please refer to chapter d1 of the at&t 345x/35xx hardware service manual
            for general information on how to install the star gate 8-port, or 16 port board.
            Some points are:

*install micro channel bus masters (boards that use IRQs) side by side, not
leaving empty slots between them.

*star gate boards can be installed in either the primary, or secondary system's
buses.

*on this description, new style boards are at&t part numbers 006-3300815 (8-port)
and 006-3300816 (16-port). Any other numbers are considered old style.

            *if we are replacing an old style board with another old style board, the tty driver
             does not need to be re-installed. If we are replacing an old style board with a
             new style board, the tty driver must be reinstalled.

Caution: do not use the auto-configuration selection of the reference diskette for
any reason.

            Old style 8-port boards require a memory space of 2000 (d0000-dffff, etc). Old
            style 16-port boards require a memory space of 4000 (d0000-d3fff, etc). New
            style 8-port boards always require a memory space of 4000.

Old style 8-port or 16-port boards do not use this parameter on the reference
diskette. Only new 8-port and 16-port boards require and i/o address.

Select any available i/o address, avoiding conflicts with other modules. It is
recommended to use the higher i/o address first (1000, 1400, 1800, etc).

8.4.4. select the require IRQ (the same IRQ is used for all star gate boards in
the system).

8.4.6.   open the internal options settings and ensure that the crom shadow entries for all
            the listed memory addresses, are set to disabled, except those for the 53c700 and
            53c720 scsi host adapters. Thisapplies to any system that includes the 53c700 or
            53c720.

8.4.7.   under internal options, also ensure that the primary and secondary mc system bus
            arbitration levels are set to the highest available level that does not conflict with
            another device.

8.5.1. check to see if the 'madf' package is installed (# pkginfo -1 madf). If present do
the following:

            *install the tty driver, taking no default values. All the required information must
             be manually added: IRQ, number of boards, number of ports, memory address,
             and i/o address.

            Note: all, new and old style star gate boards, require an i/o address during the
            installation of the tty driver. For new style boards use the i/o address assigned in
            the reference diskette; while for all existing, or new installed, old style boards you
            must use 00.

*the tty driver must be installed by performing steps 2, 3, 5 and 6, only if a
new board is added to the system.

            *if the installation is performed with the sole purpose of updating the driver with
             a new version, then all you need to do is to answer: yes to the two questions
             made by the system:

Do you wish to use the existing configuration? And do you wish to relink the
kernel?
