See the first sticky? This is just a fancier way of doing that trick
See my last response in that thread. The device and any other method you do works.
Its just that new CPUs use 5 bit multiplier selection, old ones use 4 bit. Old motherboard BIOSes dont know how to do this or adjust the fifth bit, so by putting a wire you force that bit to be on, and it remaps.
When I boot on my Epox 8KTA3+ PRO despite the fact that the motherboard BIOS is old and doesn't know about my Barton XP-M, when I don't do the wire trick
Award BIOS shows
FSB:100MHz
Multiplier: 9.5x
On boot the chip is identified as
9.5x100FSB=950MHz
Post wire trick
Award BIOS shows
FSB:100MHz
Multiplier: 9.5x
On boot the chip is identified as
18x100FSB=1800MHz

Has the remaps if you look closely. 9.5x=18x, and so on. All you have to do is look at this as you set BIOS multiplier, and it reflects accurately.
As for the wire I used, I have DOZENS of EIDE cables from everything I buy, so I took an old one, cut one of the connectors and took a strand of copper.
