I am trying to get my mobile Athlon 4 working with SETMUL on my Iwill KK266+ which is a VIA KT133 board. The CPU runs great from 550mhz to 1400mhz and hits all the multipliers in the BIOS without issues. I've modified the BIOS some to uncover some hidden settings such as ACPI disable and AGP Master Wait States. Modbin6 also has the ability to modify some registers.

According to https://web.archive.org/web/20170822100906/ht … html/Tweaks.htm the proper register to modify is 55. In my attached snapshot, I have highlighted where I think this may be, but being a novice at BIOS modding, I am hesitant to make a change. The only selectable cells are the ones with 1 or 0, the Xs are not able to be changed.

Am I wasting my time with this or can I make the modification here instead of with PCISET? I don't want to brick my board as I spent quite a few hours recapping it.
