With an 800 x 600 display, the stretching algorithm does not completely fill the
display horizontally or vertically. A greater vertical text expansion can be achieved
by changing to VGA mode 3* (see Note below). This is also an 80 column, 25 row
text mode but with an effective resolution of 640 x 350. The 350 lines stretch better
to fill the 768-line display than does the default DOS mode 3+.
Note
The utility diskette includes a program titled MOD3_350.EXE, to allow switching to
the VGA mode 3*. Another utility program, MOD3_400.EXE, is provided to put the
mode back to the DOS default of 3+.
Windows may come up with a blank screen when using Windows 3.X with
expansion turned on either through the BIOS setup or the EXP_ON.EXE utility. The
two options (second option being the best) for this situation are listed below:
• Option 1 – Pressing the
CTRL-ALT-DEL keys simultaneously. A blue screen will
display, letting you know that pressing
CTRL-ALT-DEL again will reboot the
system or pressing any key will return you to Windows. At this point, press any
key and the normal Windows screen should appear.
• Option 2 – Turn off the expansion, set the BIOS default in the BIOS setup menus
using the appropriate utility as shown in the Video Expansion Options table.
