FLOPPY DRIVE CONFIGURATION

Installation of a 1.44MB diskette drive requires the following:

ROM Revision H.8 or later if using MS DOS.

ROM Revision J.4 or later if using MS OS/2

*To find out revision of rom, run inspect or debug.

  DEBUG>  at c:\ prompt type in debug and <enter>

  type Df000:ffe6 <enter>

  at right hand side of screen you will see H.8COMPAQ.  What ever the letter and number is

  before the C in Compaq will be your rom rev.  (in this example rom is H.8)

  press Q for quit and <enter>

Requires MS DOS version 3.31 rev. A if installed as drive B, and MS DOS version 3.31

rev. B is installed as drive A.  Or use a later version of DOS.

Requires Diagnostics version 7.0 or later.
