AHCI drivers & Windows XP. Help!

I'm trying to get a new rig running, and for the first time ever I'm using SATA for my boot & optical drives.

I know I have to manually install the AHCI drivers in order to get maximum performance from my drives, but I thought I could use a usb flash-drive to do this. I'm running XP32, and an Asus tech today told me I had to use a floppy drive.

Well, my floppy drive doesn't seem to be working, for whatever reason. Bad drive, bad mobo controller, who knows?

Is there ANY way to do this from a flash drive? Some clever work-around?

If I just run my SATA drives in IDE mode, how much worse is the performance?

You would need to build XP using the AHCI drivers from the get go like you would with a RAID controller (i.e. hit F6 during the build to install a third party driver), AFAIK, you cannot do it after the install. From what I have read on Tom's hardware, there is not much difference in performance

There is a way to do it post XP install.

HOWTO: enable AHCI mode after installing Windows - PC Perspective Forums

Not sure if it's worth it though. Maybe someone else could chime in with real life benefits in doing so.

Fantastic!

Thanks, Sardi.

I just found out that there's also another way: You can use nLITE to slipstream the drivers into your SO installer, then burn a new, custom OS install disk.

---------------------
Altitude,

I was told the same thing you wrote, about the speed difference not being that significant, from an Asus tech today. (thanks) In fact, the article Sardi references above even says that these drivers can HURT performance slightly. So, maybe I'll just install with the IDE drivers , to get running quickly, and run some benchmarks. -

Interestingly, my newest mobo's BIOS has a new setting I haven't seen before: Instead of using the AHCI drive setting, you can use the "IDE" setting, but then choose "enhanced." This must be some "in between" setting wich is good for typical desktop users. (and us)

Have you got a secondary SATA controller on your motherboard such as the JMicron? If so an easy way to install AHCI drivers is to temporarily plug your boot hard disk into the secondary controller ports (set to IDE) and set your main SATA ports to AHCI in the BIOS. This will enable you to boot into Windows and install the AHCI drivers before swapping back the hard disk to the main ports.

nLITE works perfectly. Give it a try definietly.

usb sticks will work on most mobos when they´re FAT32 formatted!

but nlite is the best way to go.

How does one format a flash drive? Just run from the Disk Management - local in Windows, like any other drive?

I've read that you can damage a flash drive by formatting it. Any tips, or things to be careful of?

Allow me: AHCI can cause all sorts of problems with low latency audio performance. On my P35 based system idle average % CPU went from ~5% to 0% using legacy IDE rather than AHCI - audio performance improved no end as a result.

Hugo, thanks for that very important data. It certainly jives with other reports.

I'm sure glad I started this thread.

-But now I have a new question: If I need to run an external raid array (for video editing) can I install raid drivers WITHOUT installing ACHI drivers?

If not, should I be looking at an external raid hardware controller? (vs the software controller)

you are not doing something right in the bios...

there´s zero benefit. it´s not faster, in some cases slower and i noticed more fragmentation. all on different machines, weird.

you won´t damage your flash by formatting. yes, system control, disk management. FAT or FAT32.
