I had my parents in town for a visit but now Im back to tinkering with the Gigabyte BX2000+, Im starting to really like this board.
Because the board has 4 multiplier dip switches it should support all multipliers but the manual only lists 3.5x to 8x with added information indicating that the 8x multiplier dosnt work, please dont buy...
Gigabyte has later released this table for Slot-1 and Socket-370 motherboards with dip switches and the 8x (and higher) multiplier does indeed work (most CPUs has their ratio locked though).

But wait a minut... dip switches... there should be a 2.5x setting... and a "Fail safe" 2x setting without L2 cache... and perhaps a 2x setting with L2 cache enabled.
Gigabyte dosnt list these settings anywhere but they should™ work with all Gigabyte Slot-1/S370 boards that use 4 jumpers/dip switches for multiplier selection
2X "Fail safe" No L2: X X X X. Tested and working.
2X "Fail safe" No L2: O O O O. Tested and working.
2X With L2 cache enabled: O X X X. Tested and working. edit: Klamath only, Deschutes L2 cache gets disabled.
2.5x: X O O O. Tested and working. edit: Klamath only, Deschutes L2 cache gets disabled.
I like the fact that I found another Slot-1 board that supports the 2x multiplier with cache enabled. Too bad it dosnt support any FSB lower than 66 MHz, at least the silk-screening, the manual and the Internet dosnt think it does. I will try out all combinations with the 4 FSB selection dip switches later to see what else I can find.
