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
		ATAPI BTLD disk (if installing from EIDE CD Rom)
		CD Rom
		Serial numbers
			If upgrade you need 3 serial numbers & Keys
					Host
					Enterprise
					Xenix 2.3.4
			Non upgrades
					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.

Note: You can download the Advanced Hardware Supplement
(ftp://ftp.sco.com/AHS/5.0/sco/5.2) if you are using an ATAPI CD
as the wd driver is a lot more robust.)

SCSI Tape  Drives should be set with an ID of 2
SCSI CD Rom drive should be set with an ID of 5

If Using EIDE CD ROM  at the boot prompt:

	Boot:     defbootstr  ahslink=ATAPI

	 (If using the AHS wd driver then use ahslink=wd)


If the system has a SCSI hard disk you may need to force it e.g.
at the Boot: prompt type 

      defbootstr Sdsk=alad(0,0,0,0) ahslink=ATAPI


	Follow instructions on screen

	'r' to replace driver

	Install from     SCSI CD ROM   (Use  to select)

	CD is on the Primary Controller  select 0 as Host adapter type
	             Secondary                  1 

	If it is a Master select  0 as SCSI ID
	           Slave          1

At serial number question:

	If this is an Upgrade enter  HOST serial number and key, you will be
	asked for data. Once entered you will be asked the Xenix
	serial number and key.

	So if upgrading from Xenix to Enterprise you:

		Enter the HOST serial number & key
		Enter the data when asked for
		Enter the Xenix serial number and Key
		Don't use the ENTERPRISE Ser. No. at this point.

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


READ THIS VERY CAREFULLY:

============================================================
If going via HOST to Enterprise YOU MUST REGISTER HOST FIRST
contact SCO on 0800 136063 (ask for registration). We are
registering ALL serial numbers as BDS and not the end user.
This is done via:

	scoadmin -> Licence -> Register

If going only to host then 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.
==================================================================

If m/c is getting Enterprise then:

Install Enterprise via scoadmin -> software manager -> Install New

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 phoning SCO on the number above.

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

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.)

Load AND apply the release supplement:

LOAD: scoadmin -> software Manager -> Software ->  Patch - >
		      Load patch -> media image  (select with Down arrow)

	/usr/local/images/rs500  

APPLY: scoadmin -> software Manager -> Software ->  Patch - >
		      Apply patch -> Hard Disk 

	Select release Supplement 5.0.0d from list
	FULL apply of product.

Install ATA software if needed. This is done via:

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

	/usr/local/images/ata3        Onboards etc.
	/usr/local/images/ata5        Easy I/O etc.

Note: Don't use the ata3 drivers under OSR5 unless you really have to.

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

	Run /etc/conf/cf.d/configure and set the number of buffers

	1 ->  NBUF   to 600

	Relink kernel


Configure the printers via:

	scoadmin -> printers

Configure the terminals as normal via stalladm/easyadm

Now install the vet system from the latest backup
