NO. A Socket 7 board that supports split voltage will likely say
something somewhere about supporting the "P55C". You may find this,
or the single-voltage "P54C" designation, screened onto the board in
the middle of the socket -- underneath the CPU.

Abit's IT5H and a few other boards let you configure speed and
voltage in software. Since there's no real way for this software to
sense the chip's specs, apparently running for limited amounts of
time on too high voltage is not too dangerous.

If you can jot down the BIOS ID string (usually appears at the
bottom of the screen while booting), there are sites that can
cross-index that with AMI or Award (and I believe also Phoenix) to
identify the manufacturer.
1996 = good odds that the board does NOT support split voltages.
