Sorry , i was lazy and could only muster a cut and paste here.
a. To disable/enable sideband as the default value, please modify the registry key, SideBand, in the OEM.REG.
Disable sideband as default value:
"SideBand"=hex:00,00
Enable sideband as default value:
"SideBand"=hex:01,00
For those of you new to the joys of the MS registry do this:
Click on Start, click on Find, click on Files and Folders, set "look in" to C: In "named" type "regedit". This will bring regedit up in a box below. Drag it onto the desktop. Click on it. A registry editor will open. Click on "EDIT". In the "find what" box type "sideband". Click on "find next". A new box will open with four icons. You only want to change one of them (If you change the other three you'll corrupt your registry). RIGHT click on "sideband", click on "modify".
You will be presented with a box which contains the "hex value" you must change to disable sidebanding. Left click between "01 and 00", then drag you cursor to the left over "01" this will highlight "01", then while it's highlighted simply type "00". That's it.
