Yes sure,

IAA is Intel  optimised drivers to IDE hardware (hard drive, cd rom drives... ) it optimises the transfers and thus make your PC go faster.

the IAA site is (http://support.intel.com/support/chipsets/iaa/)

By the way I tried to install it on my inspiron but has it isn't all INTEL based chipset, it doesn't install

Please tell us more about this application and provide a link if possible.

Thank you for choosing Dell.

As previously mentioned, I tried the 2.3 and it wouldn't install (not compatable), so I tried the 2.2 whatever, and SUCCESS!

Although the difference is not night and day, it did zip up the speed on the drive. I ran Sisoft Sandra on the drive and the numbers for write and read wnt up quite a bit. A worthwhile install.

IAA is know to cause slower performance on some machines.

It also does not send the park command to disk drives before shutdown, forcing the drives to do an emergency park, which wears on the heads and may cause data loss if the drive is currently writing from it's cache. The MS driver waits for the drive to finish and then parks it.

I believe it caused the early death of one of my HDDs

I've tried it.... and it is probably one of the many reasons why my motherboard went bad.

Now I'm very reluctant to download it again for my new replacement.  In case you're wondering, the difference of performance increase is not worth it--and hardly noticeable anyway.

Hi folks...

Over the past 5-years I installed the Intel Application Accelerator (IAA) on several older desktop units to speed up the pathetically slow MS defrag routine.  It did shorten the Win98se & WinME defrag routine times by about 80% or greater on those old magic boxes.  And on 60GB drives that's substantial time savings.  Though, in each box the primary HDD's started developing a repeated scenario of bad blocks appearing on relatively new high quality HDD's.  After three drives developing "potholes" (bad blocks) in the two boxes, over several years... well, losing so much data, troubleshooting time, replacement time and money... I removed IAA from those boxes. 

As in other posts I've read in the forums, I strongly suspicion that IAA wasn't parking the HHD heads properly, and the continued off-queue parking, likely on still spinning drive platters, damaged my drives and caused me tons of aggravation with data loss and wasted time.  The time I saved in using the IAA surely wasn't worth what it cost me in data, time and money. 

Now I have no problems with bad blocks cropping up like potholes on those old units.   And the HDD heads maintain their properly queued parking position consistently. 

--------------------------  I8200 COLD BOOT  "NO OS FOUND"  PROBLEM   -----------------------------

I'd almost considered installing IAA on my year-old I8200, 2.2ghz M-4.... but decided that even if Intel has recitfied the IAA problems in version 2.2. I couldn't risk the hassles and heartbreak of injured or dying HDD's.

As it is I just installed a new HDD on the I8200 because of posts I read in the forums about "NO OS FOUND"  on cold boots... a problem I started encountering recently.  Many posters suspicioned a thermal problem with certain Hitachi drives.  ONLY AFTER removing and reinstalling the battery, module bay second HDD, and the primary HDD, with everything unplugged from all external ports, then replugged....could I boot up after one to three more "NO OS FOUND" scares.  The new HHD listed below is working flawlessly so far, and I haven't had another cold boot "NO OS FOUND" problem.... yet.
