Network Interface Type

This parameter specifies which Ethernet interface connector to use on the AM-319-20 board. There are

two possible selections: AUI (DB-15), or TPI (RJ-45) 10BaseT. If you are using the Ethernet port on the

AM-176 board, it is not necessary to indicate it on the CMOS menu.

Saving the CMOS Settings

When you are finished making changes press

ESC

. A message will appear at the bottom of the screen

asking if you wish to save any changes made. Enter "Y" to save the changes in the CMOS RAM, or "N"

to abandon any changes made. After entering your response, the system will boot using whatever

parameters are then in the CMOS setup.

Important Note

If you want to boot from a physical disk device other than device ID 0, you should create a disk driver

for the selected drive ID and MONGEN it into the monitor.

You must do this if you want to be able to

MONTST using your boot monitor

. While a hardware reset will work if the monitor contains the

generic SCZR60.DVR, because it reads the drive ID from CMOS, MONTST does not look at the

CMOS settings, and so will not know which drive to boot from unless the drive ID is embedded in the

driver.

DEVICE NAMES

Device names are how AMOS identifies the different pieces of equipment that make up your computer.

Each disk drive and other storage device has its own device name (terminals and printers are defined

somewhat differently). These device names are defined in the system initialization file.

Alpha Micro device names conform to a specific format to make it easy for you and the computer to

refer to the same piece of equipment. All device names contain three letters and a number, and end with

a colon (:). For example, DSK#:, where # is a decimal number, DSK is usually the name for a hard disk

device and STR0: is the name of a streaming tape drive.

Having names for each device lets you specify which device you want to use for a specific command.

For example, you can see a list of files from just one of your disk drives, or copy data from your hard

disk to a diskette.

You can set up your computer to use each hard disk drive as if it were two or more separate devices. In

this case, the actual disk drive is called the "physical device" and each portion of it is a "logical device."

This is an important distinction, since in most cases with AMOS you refer to the logical device name.

For example, a single 540MB hard disk drive could contain devices named DSK0:, DSK1:, DSK2:,

DSK3:, and so on.

The disk device containing your system initialization command file and other system software, the

device AMOS "boots from," is always called DSK0:. Normally this is the first logical device on the hard

disk, but if for some reason you boot from your diskette drive, the diskette drive becomes DSK0:. When

you change the device you boot from, it may also change the names of other devices on your
