Installing OSR 5 is very straight forward and should not cause any
major problems. These notes are aimed at BDS Technical Staff and
not the end user. If you are an end-user and are attempting the
install then this should make sense - if not don't try it.

These notes should be used in association with the OSR 5 release
notes supplied with the system.

              READ THIS CAREFULLY BEFORE YOU START

During installing the software you will need to phone SCO during
NORMAL OFFICE HOURS for a registration key. Make sure there is
enough time if an re-install is needed.

The complete installation and configuration will take about 2-3 hours on
a P5/75 and about 4-5 hours on a 486 DX/33.

Note: If there are ANY errors during the load START AGAIN, try switching
      OFF Internal and External cache in the BIOS during the load. If you
      cut corners here you may well get stuck later on.

Make sure you have:

	 OSR 5 Boot disk
         AHS Boot-time Loadable Drivers diskette.
		CD Rom
		Serial numbers
					Host / Enterprise
			User Licences
					As appropriate
		Latest Release Supplement
			Usually located on disk if setup in Edin, or
			on latest backup tape or an OSR 5 utility tape.


SCSI Tapes should be set with an ID of 2
SCSI CD's should be set with an ID of 5


Installation for SCSI CD-ROM is easiest.  Support for Extended IDE (EIDE) CD-ROM
requires a slight modification to the installation process.  See the EIDE CD-ROM
Installation Instructions below.  Only ATAPI-compliant EIDE CD-ROMs are useable.

Additional, more detailed installation information is contained in these files
which are readable from the CD-ROM media prior to installation:

      info/opensrvr/en_inst.txt = English Release and Installation Notes
      info/opensrvr/fr_inst.txt = French  Release and Installation Notes
      info/opensrvr/de_inst.txt = German  Release and Installation Notes


Determining your system configuration for ATAPI (EIDE) CD-ROM
-------------------------------------------------------------

If you are uncertain of the hardware configuration of your system, but you know
that the primary hard disk is attached to an IDE controller, the following
information will allow you to determine the most likely configuration.

Entries for the ATAPI CD-ROM will appear in system hardware report that is
onscreen after booting.  Look for lines of the following form, and
especially a line with the string: type=wd:

%adapter   0x01f0-0x01f7   14  -  type=wd  ha=0  id=7  bus=0  fts=d

Here, ha=0 indicates that the ATAPI CD-ROM drive is attached to the
Primary IDE controller.

%adapter   0x0170-0x0177   15  -  type=wd  ha=1  id=7  bus=0  fts=d

Here, ha=1 indicates that the ATAPI CD-ROM drive is attached to the
Secondary IDE controller.

If there is another device attached to the IDE controler, the effective SCSI ID
of the CD-ROM drive is 0 if it is configured as a Master device or 1 if it is
configured as a Slave device. If the other device is the primary hard disk
drive, the CD-ROM drive will normally be configured as a Slave device. If your
system has a primary SCSI hard disk, the CD-ROM drive may be configured
as a Master device.

If there is no other device attached to the IDE controller, the CD-ROM drive
should have been configured as a Master device with an effective SCSI ID of 0.

NOTE: The base I/O addresses and interrupt vectors shown on your system
might differ from the examples shown above.

ATAPI (EIDE) CD-ROM supplemental Installation Instructions
--------------------------------------------------
1. Insert the SCO OpenServer Boot Disk into the drive.

2. Turn on your computer and wait for the Boot: prompt.

3. If your system has a primary SCSI hard disk drive attached to a SCSI
controller, you must enter a "bootstring" to define this configuration.  For
example, if the primary hard disk drive has a SCSI ID of 0, a LUN of 0, and it
is attached to the primary bus controlled by an Adaptec 2940 host adapter (which
uses the alad driver), use the following bootstring:

   Boot: defbootstr Sdsk=alad(0,0,0,0)

If you have a different SCSI host adapter, use the appropriate driver name from
the following table instead of alad:

    ------------------------------------------------------------------
    Host adapter                                           Driver name
    ------------------------------------------------------------------
    Adaptec 152x                                           spad
    Adaptec 154x, 154x emulation, 164x                     ad
    Adaptec 174x                                           eiad
    Adaptec 274x (7770 chip)                               arad
    Adaptec 2940x (7870 chip)                              alad
    Future Domain 1650, 1670, 1680, 600, 700 (1800 chip)   fdha
    Future Domain 7000                                     wdha
    Future Domain 7000ex                                   wdex
    Future Domain 845, 850, 860, 885 (950 chip)            tmcha
    Olivetti ESC-1, ESC-2, and EFP                         efp
    Storage Plus SCSI-AT (SUMO)                            sumo

4.  When the ``Identifying the installation media device'' screen is
   displayed, choose ``SCSI CD-ROM'' as the media device type (YES,
   even though it is EIDE).

   Some machines may experience hardware driver conflicts which will not
   allow the user to choose any SCSI media devices for installation. One
   way to work around this problem is to insert a supported SCSI host
   adapter into the system. There is no need to add any SCSI devices to
   this host adapter.

5.  Select "wd" for the SCSI host adapter type.

6.  If the CD-ROM drive is attached to the Primary IDE controller in a
   system with one or two IDE controllers, select 0 for the host adapter
   number.

   If the CD-ROM drive is attached to the Secondary IDE controller in a
   system with two IDE controllers, select 1 for the host adapter number.

7.  If the CD-ROM drive is configured as a Master device, select 0 for its
   SCSI ID.

   If the CD-ROM drive is configured as a Slave device, select 1 for its
   SCSI ID.

   NOTE: A hard disk and a CD-ROM drive present on the same IDE
   controller are usually configured as Master and Slave devices
   respectively. If no hard disk drive is present on the same controller, the
   CD-ROM drive will usually have been configured as a Master device.

8.  Select 0 for the SCSI LUN of the CD-ROM drive.

9. Select 0 for the SCSI bus number.

With SCSI CD's the procedure is much easier, select the driver
to use (from the above table) and enter the ID (Normally 5).

Once the media has been verified you willbe prompted for:

Installation Type :  Fresh

Site name         :  The machine name e.g. bdsedin, bdsl etc.

Domain            :  Unless they are going via Service Provider then
		     use uucp. 

Security          :  Low

Timezone          :  No we are NOT in the states, select Europe

Disk setup        :  Select (with <SPACE>)    -   Customise
		     Swap space - At minimum 64Mb, otherwise
		                  2 x RAM, the more the better.

Bad Tracking      : If you want but will add time, not normally needed
		    for modern disks.

Networking        :  Will be default of None unless network card installed

Mouse             :  Select 'Microsoft Serial Mouse on Com 1' unless a
		     different mouse being used.

Mail type	  :  MMDF   (don't use sendmail )

The load of the software is automatic from this point on. If any errors
occur, try a 'retry' otherwise start again.


Once installed re-boot as advised.

To speed things up and reduce the load, go into single user mode
and disable scologin with :	scologin disable



If there are any additional user licences, install them via:
scoadmin -> licence manager

You will still need to register but this can be done at a later
point. It may be easier to continue with the rest and register when
install finished.

Register Enterprise/User licences by visiting www.sco.com.

==================================================================

Once the system is up and running:

If the tape drive has not been automatically linked in you will
need to run:  mkdev tape

Load the utility tape  (tar x8)
(or extract /usr/utilities and /usr/local from the most recent backup.)

Install ATA software if needed. This is done via:

scoadmin -> software manager -> Install new - > Media image

	/usr/local/images/ata5        Easy I/O etc.

(Don't use ata3 on OSR5 systems).

If there is a secondary filesystem then:

	Edit  /etc/default/accounts, so that HOME_DIR points to
	the correct place.

Add the following users via:

	scoadmin -> Account Manager -> users -> add new

Name :    admin		Password :   admin
Name :    vet           Password :   don't password account

Give admin FULL authorisations :    Highlite admin (TAB and ARROW keys)
				    Users
				    Authorisations
				      Use TAB & Return
			
Add a password to the nuucp account e.g. passwd nuucp and use the
	password on uucp.

Run our configuration program:

	/usr/utilities/init.osr

Edit the following files:

	/etc/default/tar       Set correct for the size of tape.
	/usr/local/lib/xc/.xc  Set the speed correctly
	/usr/lib/uucp          Set Devices/Systems/Dialers etc.

In order to reduce memory usage some of the start up scripts need changed,
the files below reside in /etc/rc2.d, and may or may not be present on the
version of OSR 5 you have.

	S86sendmail     Add exit 0 as 2nd line
	P86mmdf              "        "
	S25pm                "        "

Run the following:

	/usr/utilities/switchon
	/usr/utilities/smail.conf

Install edge software if needed. This is done via:

scoadmin -> software -> Install new - > Media image

	/usr/local/images/edge

Edge is now per CPU, you will have to run Edgemenu, pick Utilities
then Activate. Fill in the details, Edge is registered to the END
USER so fill in the user details, printout the form and fax to
Edinburgh. We will fax to States and get key which can be entered
via the modem at a later date. Edge will run for 60 days without
the registration key.

Hardware:

	Use   mkdev serial to add com2 if needed
	      mkdev parallel to add parallel printer support

	If there is no SCSI tape then run mkdev tape to remove it
	from the kernal

Configure the printers via:

	scoadmin -> printers

Configure the terminals as normal via stalladm/easyadm

Now install the vet system from the latest backup
