There are 3 settings for it (and these are hidden from the bios config screen). The current value is 2 which is the default.
Select option: 'HDC Configure As' [ VarStore: '0x39', QuestionId: '0x1c', Help: 'Set Harddisk Controller Configure Type'] Option: 'IDE' [ Value: '0' Default: 'false' Type: 'int8' ] Option: 'AHCI' [ Value: '1' Default: 'false' Type: 'int8' ] Option: 'RAID' [ Value: '2' Default: 'true' Type: 'int8' ]
According to the rapid store util docs this is possible to have raid and IDE (which is what I think setting 2 is). It also jives with what windows is setup as. My drives are in SCSI/RAID mode in device manager. Also all the other utils I have used say 'IDE mode'. Tad reluctant to just flip the switch and see what happens as this is my only computer at the moment.
I will probably disable rapid store first. Double check the reg settings. Then flip the switch using the boot usb drive I have with the EFI prog on it.
It looks like it would be totally possible to write an EFI/UEFI boot program that lets you control all of this information as that is basically what most config screens are now. The problem is there are zillions of different bios/firmwares out there and each one stores its settings in different places.
