Configuring ROM-DOS 3-11
Displaying Different Code Pages
To display a code page other than the hardware code page, you must
load DISPLAY.SYS in CONFIG.SYS. The following command sets the
display to show code page 850, assuming both the DISPLAY.SYS driver
and the EGA.CPI font file are located in the C:\DOS directory:
DEVICE=C:\DOS\DISPLAY.SYS 850 C:\DOS\EGA.CPI
The available font files are named EGA.CPI and EGA3.CPI. They are
both used for EGA and VGA systems.
If you have an EGA or VGA system, the character fonts are immediately
switched to the requested code page. Some characters may look
different after you load DISPLAY.SYS because ROM-DOS uses its own
font for all 256 characters. For example, your hardware font might use a
square-like zero character, but ROM-DOS might use a round zero
character. The differences are minor.
Printing Different Code Pages
At this time, ROM-DOS does not support printing code pages other than
those stored in the printer hardware.
Changing the Keyboard Layout
To alter the keyboard layout, issue the KEYB command from within DOS.
You can do this by running KEYB in AUTOEXEC.BAT or directly from a
DOS prompt. Use this following command to switch to a German
keyboard layout, for example:
KEYB GR
