If your problem on the Pal was joining the L1 bridges, they are joined already on the TBBs.
Older mobos did not control the 5th multiplier bridge, because when they came out Athlons had only 4. As result only the 4 lower bits of the multiplier code are set by the mobo. If your TBB comes with a multiplier of 13 or higher (2100+), the 5th multiplier bit is always high (5th bit of L3 open), meaning you can only set the multiplier code to high multpliers (13 or more), without a mod. If your TBB comes with a multiplier of 12.5 or lower (11x for 1700+), the 5th multiplier bit is always low ( 5th bit of L3 closed) , meaning you can only set the multiplier code to low multpliers (below 13), without a mod.
Search on johncar or soulkeeper. johncar has a lot of pages on this on his site. You really should be able to unlock a Palimino also.
