To perform the Sequential Read/Write Test:
Highlight "Fl o p py" in the main menu by using the left and
right arrow keys. Below this menu is another menu which lists
all possible tests available for the Floppy drive. At this Floppy
Disk Menu, "Diskette format" should be highlighted with the
bar cursor. Use the down arrow key to highlight "Sequential
Read/Write Test." Press < ENTER> . That causes the
Diskette format box to appear on the left side of the screen.
The box contains the following questions (fields) that must be
answered with appropriate responses. These are:
Floppy Disk Drive (A/B)
Proceed (Y/N)
The response for the first field depends upon the response
given in the CMOS Setup screen. If the response entered 'by
the user at the CMOS Setup screen was "A," this field will
automatically display "A." If the response entered by the user
at the CMOS Setup screen was "B," this field will
automatically display "B." To change the response, enter the
appropriate value at the CMOS Setup screen. When you are
satisfied with the information entered for the first field, enter
"Y" at the "Proceed" field.
