Well I think there will be requests like same probability that you capture your

Anyway I will prepare the DIY guide.

The old text suggest this. All I think is that the bios left the controller in
interrupt mode and I think our driver assumes always the SMI mode.

I thought about this but for the reason that serverworks was bought by broadcom
and we have ATI and others there so best sounds to me to make it more global.
