Look in your C:\config.sys file and see if you find any line with a reference
to the
"bi-di.386". If you see it, type "rem" without the quotes at the beginning of
that line, save the changes and reboot.  If for some reason the machine
should not boot up after this change is made, then boot the computer into
DOS, & undo the "rem".
Good Luck
