Remember, this is only an example. Your computer may be set up to reference the hard
disk as more or fewer than three logical devices. If you want to see a list of the hard and
diskette disk devices on your computer, type SYSTAT and press
RETURN
; the end of the
display lists the available disks.
At some time in the future you might decide to change the number of logical devices on
your hard disk. This is a sophisticated procedure, so for detailed instructions, see the
document "Configuring Winchester Disk Drivers" in the
System Operator’s Guide , and
follow the FIXLOG reference sheet in the
System Commands Reference Manual .
The System Disk
The System Disk, DSK0:, is where the system software is stored, and where the
computer looks for it when the computer boots. Usually, DSK0: is on your hard disk, but
you can also set up your system to boot from a diskette, in which case the diskette drive
would be DSK0:.
If you have a magnetic tape drive included with your computer, you also have the option
of booting from this device if you are unable to boot from your hard drive. Booting from
a tape medium is known as a "warm boot," and is usually reserved for special
circumstances when it’s not possible to boot from your normal System Disk on the
hard drive.
DISK ACCOUNTS
Disk accounts are an organizational feature your Alpha Micro computer uses to help you
keep track of your data. Instead of making you search through one enormous list of files
for the specific one you’re looking for, the AMOS operating system is designed to group
files into "accounts."
Accounts are identified by a two part account number. The two numbers are separated
by a comma and enclosed in brackets. The first number is called the project number,
the second part the programmer number. [1,2], [200,0], and [34,11] are examples of
account numbers. Since they are actually octal numbers, the digits 8 and 9 aren’t used,
and the highest possible number is [377,376].
The two part structure of the account number allows you another level of organization.
Besides grouping files into accounts, you can group related accounts in the same
project. For example, all accounts containing files dealing with payroll may be in project
50 ([50,0], [50,1], etc.).
You can also assign a password to each account if you wish, as a security measure.
Anyone who doesn’t know the password cannot log into the account. See Chapter 5 for
how to assign passwords.
