I got the 33 mhz/64   386 motherboard a couple of days ago.
In the case it came in, I hooked up a small disk drive
and a monochrome hercules card. When I ran it, an old version
of
Norton's gave about SI = 44. I moved the board to a larger case
with the same disk controller, and bigger drive, but a paradise
vga card driving a monochrome monitor.
Now Nortons gives me SI = 23. CHIPTEST from the "the last byte suite"
claims that the it's a (16.4 Mhz 386) now. 
Without measuring clock frequencies by hand, how does one tell what's going on?
The AMI bios does not have a low level "twiddle the bit" set up program
like the one I have on my 386sx.
The chips are 85C310 ( two 8 bit registers) and 85C320 ( one 8 bit register).
iHowever, I don't know the port addresses, or what bytes in the CMOS ram hold these config. bytes.

Any ideas on how I converted my speedburner into a horse drawn
wagon?
