Andy van BXBoards heeft wat info gepost over het wazige BH6 beta BIOS met mysterieuze busspeeds:
I flashed my BH6 (I found it!!) with the KK BIOS (scroll down a bit for todays earlier update!!) and although you now get loads more bus speeds reported in the BIOS, these DONT work. If you select 81Mhz, this gets rounded down to 75Mhz etc. Some bus speeds don't work at all, and a blank screen results.
OK, well its probably not worth flashing, especially if you have an original rev. 1.01 board which will have the original clock generator. You may be able to use these speeds on a later revision of the board however. I do not recommend you use this, but here it is your own risk.
Het lijkt er dus op de extra busspeeds helemaal niets doen.
