Thanks Zack, Bryce, everyone else.  My BIOS showed "CPU Speed" set at
"100/100 MHz".  Couldn't find  "FSB" or similar so I figured this must
be it.  I found I could select either "100/133 MHz" or "133/133 Mhz" so
I chose the latter (blindly).  As predicted, my system now proclaims
"AMD Athlon(tm) XP 2200+".

I hope this helped someone else too.  Again, thanks!
