You can also delete the ESDI_506.PDR file in Windows/System/IOSUBSYS directory in Command Prompt in F8 menu after you install Windows. Either way, you'll revert back to 16bit realtime drivers (normally used in Safe Mode) which are slow. OR, switch the SATA mode to RAID, then you'll not need to do anything! It will not use the ESDI_506.pdr, and you'll simply have a unknown RAID controller in the Device Manager, and no IDE stuff. Still realtime drivers
