FAT: change DOS installer to EXE; additional 32K limit fixes
Additional fixes for the 32K limits in the installers. In the case of the DOS installer, that means changing it from COM format to EXE format (since COM format has a 63K hard limit); retain the name for user compatibility, though (DOS doesn't care what the extension except for pathname search; if it finds an MZ EXE header it will use it.) With the change to EXE means having to handle more than one segment. Since we don't have a real DOS compiler we have to wing it a bit. Signed-off-by: H. Peter Anvin <>
