IBM PCjr

If you decide to discontinue running the diskette-drive
test and return to the First IBM PCyr Test Menu
Screen, press Fn and then press Break.
1 After the screen showing an erased
diskette appears, insert a blank
diskette in your diskette drive.
2 Type the letters MPNP. These
letters wiU appear in the upper
left-hand corner of the screen. This
tells your IBM PCyr that you have
inserted a blank diskette. (If you
type the wrong letters, your IBM
PCyr will beep once and wait for you
to type the correct letters.)
