AK35GTR v1.2 + Athlon XP 2100+ T-Bred B

I have an AK35GTR v1.2 motherboard with an updated BIOS of AK35s00j.bin (modified to have the latest bios for the highpoint 372) and an AMD Athlon XP 2100+ T-Bred B. The Athlon XP 2100+ T-Bred B should be unlocked right?

My question is, shouldn't I see more than just 12.5 multiplier on my BIOS options? Right now I can only choose in the range of 5 to 12.5 multiplier. I thought that being it (my proc) unlocked, I should see options 13 and above multipliers, right?

Thanks you for reading my post guys and I hope you can help me with my dilemma.

Try to set the multiplier to 7, and see what happens. The BIOS most likely will work with the 'correction factor' of '+8'. Meaning, if you set the multiplier in BIOS to 7, the BIOS will interperate this as 15, and so on...
