Before attempting to install Altos CP /M 2.26F", read this
document carefully.
It is assumed that this is an installation

on one of the following Altos s y stems:
• ACS
• ACS

SUS-IS
S888-12

• ACS S.IS-I4c
• ACS SIII-15

Currently, the maximum hardware configurations supported are:
2 - Floppy Drives
~
1 - 8-inch Bard Disk Drive (-18, -12, or -14
The file structure supported by this ver sion is exactly
co mpatib le with vers ions 2." or greater of MP/ M II.

The file

structure on the hard disks is different from the hard disk file
structure used in either CP /M 2.24 or MP/M 1.1.

Memory: This version of the CP / M uses all four banks of memory
available on the Altos computer systems.
The TPA area (User
Area) has been increased to SSIt.
Bank 0" contains the CP / M
operating system, jump tables, allocation vectors and disk
parameter blocks. A copy of the CCP is kept in Bank 1 for warm
boot.

)

Disk Cache: Up to 80 K of memory fr om Bank 1 and Bank 2 ar e used
for I /O buffering for hard disks.
Whole tracks are read and
written at a time. This reduces disk access substantially, and
reduces response time.
In addition to the disk cache for hard

llay 4, 19S2

CP/M

IBS~TIOB

IBSTRUCTIOBS

Version 2.26PI

disk I / O, directory tracks are buffered in a separate bank. Up
to five tracks of hard disk directory space "is al ways maintained

in memory. This pro vides for instant access to about 1500 4K
Block size directory entries. The directory buffers a r e written
to the disk during a warm boot and a write to the directory
sec tor.
De- pe nding on the application, this scheme has improved

the performance up to a factor of four over the earlier ve rsions
of CP /M and single user MP / M.

2.'

IBSTALLATIOH IHSTRDCTIOHS

If you have already installed MP/M II, then there is no need to
run the diagnostics or the hard disk initialization program.

Otherwise, before you install CP/M on your system, you should run
~ the diagnostics and BRDINIT8 from you r diagnostic disk.
BRDINIT8 will create the bad sector table and assign alternate
sectors to the bad sectors. You should have ALTOS Diagnostic
Monitor Version 2.6. ~

This section discusses the Altos CP/M version 2.26F0 of CP / M
ve rsion 2.2 from Digital Research, Inc.
You should also
familiarize yourself with the CP / M User's Manual.
Altos
recommends that you perform the following tasks upon setting up
your system to insure retention of disk data.
Unless otherwise
stated, an asterisk ' (*) within a user response to a prompt is
part of the command and must be entered.

l )

a. Make a backup copy of the system disk and store the original
in a safe place. Use the copy for daily operations.
l. If your system has only one floppy disk dr ive and a hard
disk, refer to section 4.1 for instructions.

2. If your system has two or more floppy disk drives, refer
to section 4.2 for instructions.
In all cases, the utilit y programs provided on the Altos ADX
diagnostic disk supplied with your computer system are required.
b. Review the CP / M User's Manual t o become familiar with the
operating system.
c. Read these instructions thoroughly.

CP/M FILB DIllSC'fORY

If you wish to see the file directory of your CP / M s yst em d isk,
after recei ving the system prompt A>, simpl y type DIR, press
RETURN and you will see directory on the screen.
If you wish to

4.2

Double-Density, Single-Sided Backup Procedure

When making a double-density backup copy of the system disk,
llay 4, 1982

./

CP/N INSTALLATION IRSTROCTIONS

Version 2.26FlJ

proceed as follows:
a. Format a blank disk for double-density using the FLPY or the
FLPYFORM utility of the ADX diagnostic disk.
b. Place the system disk in Drive A, the blank, formatted disk
in Drive B; boot up the system.
c. Make a backup copy of the CP/M system disk using the FLPY
utility of the ADX diagnostic disk.
Initially, the system is set up for an ACS 8999-19 system.
will also support ACS 8999-15.

This

There are two files provided to support the other configurations.
The files are:
__

l.
2.

CBIOS29.COM support for ACS 8999-12
CBIOS49.COM support for ACS 8999-14

You should rename one of the above files to CBIOS64.COM to get
the correct configuration for your system. You will have to
reboot the system to get the correct configuration after
renaming. Run DISKSTAT to get information about your system.
The default names for the various logical devices are:
---------------------Drive A = Floppy #1
Drive B = Floppy #2 .

l)

The number of logical hard disks available is dependent on the
type of system you have:
(-19, two
logical drives (drives C and D)
(-12, three logical drives (drives C, D, and E)
(-14, five logical drives (drives C, D, E, F, and G)
Functions Not Currently Supported:
1. Only one hard disk is supported.
2. Mode 1 (blocked double-density) not supported.
3. Ability to change names assigned to logical devices.

5 ••

CPIISBTOP

The CPMSETUP program allows you to change certain parameters
about your system such as console and printer baud rates. In
addition, you will be able to cause your system to boot from the
hard disk instead of the floppy disk. The changes are made to
CBIOS64.COM file, and take affect only after a reboot.

Nay 4, 1982

CP/K IBSTALLATIOB IBSTRUCTIOBS

Version 2.26PI

Procedure for Running CPIISE'fUP:

Invoke CPMSETUP .
The screen will display the following menu:
1. Copy bootfi1e to hard disk.
2. Console baud 'rate se t up.
3. Printer setup.

4. Update setup.
5. Exit

Following is a brief description of the above functions.
1. Copy

bQotfile to hard disk
fUnction copies the boot records to the hard disk so
system boot can be performed from the hard disk.
Note
the boot tracks for the CP / M and HP j M-are the same. If

YOll boot from hard disk, the logical names will be reversed.
Use OISKSTAT to get the names assigned to the logical
devices.
2. Console baud rate setup

This function is used to setup the baud rate for the primary
console.
(CP/ M supports only one console.)

(

3. Printer setup
CP/ M supports only one printer. You can choose either a
parallel or a serial printer using this function. If you do
not have a parallel printer, then you can change the baud
rate for the serial printer.
4. Update setup
This function actually changes the parameters in the
CBIOS64.COM file. Select this function after you have set
up the printer and console.

This fUnction allows you to exit the CPMSETUP program.

CP/K VBRSIOB 2.26pl COKKARDS

Altos release 2.26F0 of CP / M version 2.2 contains many commands
applicable to the user of 8500 CPU PCB Computer Systems. Three
of the most used commands are described below.
CPKSETIIP

This command is discussed in section
1.2.

!lODE

Allows the user t o change the density of
any floppy disk dr ive. This command is
of particular value when the user has a

llay 4, 1982

Version 2.261"8

CP/M IBSTALLATIOR DlSTROCTIORS

default density

wh~ch

is different from

the- density of the various applications
software disks used.
If the user
forgets to change the density on a
floppy and attempts to read from or
write to a disk which is in a different
density, an error display will be

generated which would indicate that a
software or hardware problem existed.
The MODE command is contained on the
CP/ M disk. To invoke the MODE command,
enter: A>RODE

Instructions on how to select the drive
and density you wish to alter will be
given.
An Altos written program that allows the

DISKSTAT

user to obtain information on floppy and
hard disk I / O errors are suspected.

The screen display should show:
Select :
AL~S

DISKSTAT

 is an ambiguous file name as described in the CP / M

manuals.

For example, the command:
F'l'P *.0011

sends all of the .COM fil es to the receiving side.

Whereas:

FTP FILE. RAIl

sends only file FILE.NAM.
The sending FTP periodically types an
's' while waiting for the receiver to become active.

The receiving side is started by one of the following commands:
~

or nP a:

where 'u' is the drive letter of the destination disk.
If no
drive letter is specified, the logged disk is the destination
disk. The receiving FTP periodically types a 'WI while waiting
for the sender to become active.
Since the recei ving side
normally does not exist by itself, enter [CONTROL} C to get back
to CP/M .
The Pile Transfer Prograa is copyriqhted
by the Balcones Co-puter Corporation.
