Hi, This is probably a very trivial question, but I'm not an MSDOS programmer. I just found a public domain device driver source in assembly language. Could you tell me how to assemble this thing to create a device driver with a .sys extension? I have an XT compatible with masm, if that matters. Thanks a lot, --Ismail Dalgic dalgic@cs.stanford.edu

In a nutshell, a device driver is similar to a .COM file but the ORG is at 0h instead of 0100h. So after you compile and link it, pass it through EXE2COM (freeware) or EXE2BIN (comes with some versions of MS-DOS), and rename the resultant binary file with a .SYS extension. ...
