IBMBIO.COM looks for HIGH | LOW, UMB | NOUMB when scanning the DOS= directive. HIDOS=ON is similar to DOS=HIGH..., HIDOS=OFF is similar to DOS=LOW. DR-OpenDOS 7.02+ additionally scans for AUTO and NOAUTO arguments but does not make much use of it for now, so there's no backdrack when omitted. Chicago's ENHANCED and SINGLE arguments are accepted, but ignored because they make no use under DR-DOS. (BTW. If you have look at the end of the IBMBIO.COM file in a binary viewer, you will see a list of valid directives and arguments. But please mind, that these strings are overlapping each other, that is they are merged together to save space, so you will find "NOUMB", but not "UMB", you can find "HIDEVICE", but not "DEVICE", etc. You will need some phantasy to figure out all the possible commands... ;-) ) Matthias ------------------------------------------------------------------- Matthias Paul, Ubierstrasse 28, D-50321 Bruehl, Germany eMail: Web : http://www.rhrz.uni-bonn.de/~uzs180/mpdokeng.html -------------------------------------------------------------------
