Disk Memory System

The prompt MASTER DISK (1 - 3)? has already been answered as 1 because you

selected single disk operation. You can answer the prompt NEW DISKNAME? with any

valid name up to ten characters long. Valid diskette names can contain any characters

with ASCII codes of 32 through 95. with the exception of the period and the space

character. since the Disk Manager module recognizes

only

characters in this range. (See

the

User's Reference Guide

for a complete list of ASCII character codes.)

For best results. use only upper-case characters A through Z and other characters with

ASCII codes of 95 and lower in naming both your diskettes and your files.

Your response to the next three prompts depends on the types of disk controller. disk

drives. and diskettes you are using. The TI Disk Controller Card. Model PHP 1240.

supports up to 40 tracks of single-density data per diskette side. The type of disk drive

and diskette you are using determines whether or not you can write to and read from

both sides of the diskette.

In answer to the prompt TRACKS PER SIDE? enter

40.

Most disk drives support 40

tracks per diskette side.

Note:

Some older drives may support only 35 tracks per side. If

your drive is one of these. enter

in response to this prompt.

In response to the prompt SINGLE SIDED (YIN)? press

and then press

ENTER

if you

are using a single-sided disk drive. If both your diskette and disk drive are double-sided.

enter

(For more information about diskette types. see page 5 of this manual and your

disk drive manual.)

In answer to the prompt SINGLE DENSITY (YIN)? enter

since the TI Disk Controller

Card supports only single-density data. Although double-density diskettes may be used

with the controller. data will only be recorded in single-density format.

When you have answered this prompt. the initialization process begins. The time

required for initialization is approximately one minute for a single-sided diskette and

about two minutes for a double-sided diskette. The message

INITIALIZE NEW DISK
WDRKING .... PLEASE WAIT

is on the screen for a moment. Then the message 0

WORKING .... PLEASE WAIT

appears. followed by 1

. and then 2

The number 2 is increased by one as each sector

is initialized.

After the initialization process. the message

DSK1 - DISKNAME

diskname

AVAILABLE

nnn

USED

nnn

appears. Each sector that is unusable increases the USED number by one and decreases

the AVAILABLE number by one.

The following appears at the bottom of the screen:
