How big exactly is the update program + BIOS image? You said it doesn't fit. Is it some kind of .EXE sfx, already compressed, or what? Naively, I wonder if you tried 7-Zip to compress it. Then, as long as you have about 60 kb free, you can add 7zdecode.exe (or use UHarc or even paq8o8z or such). >> You don't need everything on one floppy. Put the BIOS image on a separate >> floppy.

RUFUS is not very big nor complete, by default, unless you use the full 1.1 .iso. How big is your USB jump drive? > I don't want that.

You probably need to copy /b the shell to a RAM disk, then "set COMSPEC=R:\COMMAND.COM" or such. ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
