ext Mode Pages Test
The Text Mode Pages Test checks the video subsystem's
ability to map and present all available video pages on
the monitor screen, one page at a time. The test displays
eight successive screens, the first of which contains 21
lines of 77 zeros. The remaining seven screens are identi-
cal to the first, except that each screen substitutes a
different numeral (1 through 7) for the zeros.
Type y if all the rows of numbers on each screen are dis-
played correctly; otherwise, type n. Figure A-7 shows an
example of the first of these screens.
