Inspiron 1100 bios mod/hack to support full speed Pentium 4?

So my Inspiron 1100 has the newest bios available from Dell, A32. I decided to upgrade it to a 2GHz Pentium-4 Mobile. It works, kind of, but not at full speed. I see I am not the only person who has this problem. It is running with a 12x multiplier, at 1.2GHz. The bios recognizes it as a Pentium 4-Mobile but it simply will not run at full speed no matter what. I've used every speedstep utility out there and even tried to mod the bios using Phoenix Bios editor but it says "no bcps found".
Any ideas?

I have the same problem on my inspiron 1100 with a Pentium-4 Mobile 2.5GHz. Haven't found a solution yet, but I'm going to try these tonight:

Notebook Hardware Control

Both claim to be able to adjust the CPU multiplier on the fly.

there's a 2.4 and a 2.6 upgrade for this thing so the 2.5 was never officially released for use with this laptop.
Is that 2GHz an official upgrade part from Dell or just bought at an e-tailer/ebay? Chances are it's not supported either.
