I have a bunch of computers (HP) running XP where the SATA emulation is set to IDE. I would like to change that to ACHI during deployment without the tech having to do anything manual. when I use the HP BIOS Config utility post applying th eimage, the system goes into repair and wll not boot, so I assume I have to do this during WinPE.
Any hands on experience you can share?

I assume that the system went into repair mode with bluescreen code 0x0000007b.
Here is what I did:
Just leave BIOS settings with IDE and go through your deployment.
Run this registry fix before applying HP BIOS change:
reg add HKLM\SYSTEM\CurrentControlSet\services\msahci /v Start /t REG_DWORD /d 0 /f
In fact, you may switch between IDE and AHCI mode.
Hope that helps.

In my experience, switching the SATA operational mode after imaging is a bad idea, especially if your disk contains some form of wholedisk encryption.
I'm not sure how the HP Bios tool works but the Dell Bios tool produces an EXE than can be ran to make the switch. (I'm not sure if it can be ran in WinPE. Even if it does, it would certainly require an additional reboot for changes to take effect.)
In my own environment, it's simply a given that the SATA switch to AHCI is something requiring manual intervention.

Well, i got it to work thanks to Betty, she just forgot one key mentioned here. Once I had the values i could create an HP REPSET file to change the mode during TS with no extra reboots.
Thanks for all the help.
