Hi!
You need to set the right keyboard type in your config.sys... I believe it was:
Code:
country=034,850,country.sys
install=mode.com con cp prepare=((850) ega.cpi)
install=mode.com con cp select=850
install=keyb.com sp,,keyboard.sys
(you should replace the filenames with the full path of the files, of course...)
This will then give the correct key/character translations. You can switch back and forth to the US translation using CTRL-ALT-F1 and CTRL-ALT-F2 if you wish. (maybe this is what you accidentally did?)
greetings,
alex
