Hello,

I've always wished to have a dual-CPU PC (to install OpenBSD on it)
and finally my employer gives me 3 HP Kayak XA-s 7/500 minitowers,
each carrying a single Intel Pentium III CPU (500/512/100/2.0V s1)
and having an "AMP"-thingie inserted into the 2nd CPU slot on the
motherboard.

As a quick test (I intend to buy 3 more CPUs on Ebay later) I have
inserted a Pentium from one minitower inplace of the AMP-thingie on
another minitower and the latter still boots fine, but doesn't
recognize the 2nd CPU. The PhoenixBIOS 4.0 6.0.J white screen prints

    Processor 1: Pentium III
    Processor 2: Not Present

1) Do I have to switch some jumper on the mainboard?

2) Where could I find the mainboard layout (is it Intel 440 BX)? At
http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&locale=en_US&docIndexId=179911&taskId=130&prodTypeId=12454&prodSeriesId=32579
I've only found the layout for a single-CPU mainboard sofar...

3) Will every Pentium III 500/512/100/2.0V s1 I see on Ebay work
   there as the 2nd CPU?

4) What's the highest speed of P3 I could insert there, 600 MHz?
   (I think I'll stick with 500 MHz anyway, but just of curiosity)

Thank you
Alex
