>Description:

	my piixide1 stopped working after the following change:

> revision 1.29
> date: 2006/09/03 18:30:35;  author: xtraeme;  state: Exp;  lines: +119 -3
> branches:  1.29.4;
> * Add support for ICH8 and ICH8M SATA/RAID controllers.
> * If the controller is in AHCI, ask for SATA IDE mode of operation.
> 
> jsg@openbsd says:
> 
> "X60/T60 Thinkpads are shipped in AHCI configuration by default,
>  this makes them work without changing a BIOS option."
> 
> Tested by eye of the beholder. From OpenBSD.
