Is your coppermine P3 a 100MHz FSB or a 133MHz FSB part. What kind of P3 is the slot1 chip you have. If it's not a coppermine, you may need a BIOS update to support coppermine CPUs, or even just to support later versions of them. Bios updates add support for new CPUs by adding updated microcode, which is a small set of code loaded onto the CPU to help it function properly, like working around slight bugs in the design.
The BH6 has the legendary intel i440BX chipset, which technically doesn't support 133MHz (although practically every i440BX in existence will overclock to 133+ MHz in a heartbeat, hence the legendary status
). It may get confused if you feed it a FSB ID signal for setting 133MHz.
Also, I don't know for sure, but some slotkets are only for 66/100MHz FSB chips. I think you need one designed for 133MHz to run 133MHz P3's. Many slotkets have jumpers to force a certain FSB signal, and also some can set voltage ID signals, too. You might want to look over yours to make sure that any jumpers are properly configured. Also, just to say it, make sure the slotket is pushed in all the way. Since it has two rows of contacts like an AGP slot, and if it's kind of stiff, it might not slide through both sets of pins in the socket unless you push it hard enough. It will feel kind of like a 2 stage snap into place.
BTW: I had a BH6 a while ago. It is an awesome mobo for P3's. One of the best!

It works...)
I googled beep codes, and, assuming it's an award BIOS, that is the bad video card signal.
