Sp0iLedBrAt Posted March 15, 2010 Posted March 15, 2010 If you do it that way, you will NOT get AHCI. Listen to these guys:1.Download the file I've attached and double-click it. This will import info to the registry.2. Go to Windows\System32\drivers and put iastor.sys there.3. Restart4. Go to BIOS and set AHCI instead of IDE, save changes and exit5. When XP boots up, it will ask you for AHCI drivers; point to the folder where you keep the Intel SATA/AHCI drivers6. That's it. EnjoyINTEL_AHCI.reg

EnjoyOh Wow !As simple as that !Now I can understand that and I just hope it will be worth all the headbanging - I just got this from ASUS - The latest SATA devices that the board can support are SATA 3Gbit/s drives.. and support the advanced SATA features that go with SATA II like NCQ and HotSwapping... However, it can't support the new SATA 6Gbit/s protocal...SATA 1 ~ 6 support 3Gbit/s bandwidth.The advanced SATA features can help in a business or Enterprise environment but they are not as useful to a home user.Performance of the system in terms of application operation will depend very little on the SATA protocal... IDE or AHCI... although in some cases, RAID can increase data loading performance ... generally a small portion of the total application running time.LOL - seems I may be chasing a dead duck but at least i'll know it's as it should be.I'd be interested to hear if anyone has noticed increased performance from IDE to SATA

What can say? Any ideas ? HELP !!!
cdob Posted March 16, 2010 Posted March 16, 2010 (edited) copied the iastor.sys to the file sytem win32 folderDid you copy file to system32\drivers\ folder? Edited March 16, 2010 by cdob
outsounder Posted March 16, 2010 Author Posted March 16, 2010 copied the iastor.sys to the file sytem win32 folderDid you copy file to system32\drivers\ folder? YES! IT'S SETUP AND WORKING I'd mistakingly put the whole folder with some random name int system32\drivers, when I realised that and corrected, all went exactly as you explained, rebooted, changed to SATA in Bios, pointed to driver folder on desktop, it found new hardware and in it all went !I really do appreciate your help on this one guys, I'm going to have a look at the reg file you attached in detail to see what I can learn from it.What i'm going to do now is image this setup, run a bench test, the restore the old image without SATA to see what performance differnce there is - I run a simple bench test earlier which showed double the transfer rate - it was up to well over 200mbs from 100, however when I ran the same little app this evening, it was down to just 26mbs transfer...???What utilty do you guys use for accurate speed testing ?Are there BIOS tweaks I can play with as well? hehe, I'm like a child with a new toy now Can't thankyou enough, i'll post the test results here later once i've found a good reliable app to test it with !!!
outsounder Posted March 16, 2010 Author Posted March 16, 2010 copied the iastor.sys to the file sytem win32 folderDid you copy file to system32\drivers\ folder? YES !!! IT WORKS !!! I had place the folder (which ahd a silly name to remind me what it holding the iastor.sys into the driver folder,once I realised what i'd done and placed the iastor.sys in the drivers folder as described, I rebooted, it found new hardware, pointed it to the folder on the deskop holding the AHCI/SATA drivers and in they all went, smooth as yoghurt ! So now all is as it should be and I have a SATA II mobo with 4 SATA II Drives, exactly what I bought with IDE or Ultra DMA in sight !Now I want to run a speed test then go back to bios, go back to IDE and run the same test there, better imag the dive first though !Whats the best little app to run that test, I got one called bench test wich showed 100mbs in IDE, over 200 in SATA but when i ran it just now, the transfer rates gone down to just 23 !!!Really really grateful for all your help on this guys, i'll post the sped test results here later to discuss.Cheers !!!
