The compaq internal drive controller is specially designed by compaq and
conner and only compaq (or conner) drives are compatible.  The compaq
esdi controller confirms to the industry standard for esdi drives, all
esdi drives should work with it.

When a compaq computer boots normally, it beeps twice.  If it boots at
less than the maximum cpu speed, it only beeps once.  You can change the
cpu speed using the mode speed command from dos.  If the machine beeps
more than twice, something is wrong.

Hope this helps.
