Abstract
A personal computer when attempting to boot from a diskette (5) searches the boot record of the diskette for com. When found, com and the eight characters preceding com in the boot record are compared with the first two entries of the directory of the diskette. If no match is found, the personal computer responds on the basis of the diskette being a data diskette. Otherwise, the personal computer executes the boot record of the diskette. This minimizes error messages and operator involvement.
