Hi f/f george.  You wrote:

One long and then 3 short beeps means you have a video problem.
A continuous single beep means a power problem, repeating short beeps
also means a power problem.

Instead of a single beep, it boots up with a Morse code "B."

Dah-di-di-dit.

The CMOS says I'm running a "Pentium III 1@@@" MHz (One-at-at-at), but

that

doesn't seem to cause a problem.

Thanks for doing the footwork for me on those beeps.

Correction by the way: on bootup, the CMOS says, "XPS T@00, Pentium Pro
1000"  That is the best it can comprehend about my 1.4 GHz Celeron upgrade.

It used to say XPS T450, etc...

Well, Powerleap said there would be little things like that, but not to
worry about it.  So I'm not worried.  Of course, my beep-warning function
has become useless, although amusing.
