Copying the 3.3 files (io.sys and msdos.sys) isn't quite enough as the bootstrap loader on the first sector of the partition tries to load ibmbio.com and ibmdos.com the next time you reboot your computer. SYS C: will take care of that, though. What comes to the original question, I haven't encountered any problems running IBM PC-DOS 3.3 in a variety of clones over the last couple of years. I haven't ever bothered to compare whose manufacturer's dos gives the biggest tpa but there shouldn't be a big difference. Of course it is wiser to use the dos you received with your pc as it may contain some added value features like support for dos 4 partitions etc. >Jack Lupic Jari Artes
