This is a known bug in MS-DOS that triggers another known bug in the DJGPP real-mode stub only when you boot your computer without an 'autoexec.bat'. The cause is a null definition of the PATH environment variable. The workaround is to put an 'autoexec.bat' on your floppy disk, even if it has no instructions in it. I thought the bug in the stub was corrected in v2.01, but apparently you'll have to wait for 2.02 to get a more permanent solution. --- --------------------------------------------------------------------- | John M.
