Intel® Application Accelerator

I read somewhere that I could improve my I/O performance by installing the Intel Application Accelerator. I checked it out on Intel's website (link), and it requires I first install the Intel Chipset Software Installation Utility...anyway, all of this is making me nervous and I was wondering if it was really worth it, or if there was any chance this would mess up my system.

I'm running Win2k on a celeron800 laptop (slow HD, something like 4500 rpm).
Anyone tried it or has comments?
thanks!

 
Hehe. Application Accelerator, sounds like trouble to me...

Anywho, I doubt this could do a lot for ya, your HD seems like it would be a bottleneck to me.

Just my $0.02
 


<< Hehe. Application Accelerator, sounds like trouble to me... >>

sounds more like someone who doesn't know what he's talking about.

if those drivers are compatible with your chipset, go for it. you'll probably notice a significant difference, especially if you haven't updated your ata drivers.
 
If you have a Celeron 800 laptop, it's unlikely that you have a chipset which is compatible with the IAAs. Most laptops of your speed generally come with with 440MX chipset...which is not compatible.
 
Intel Application Accelerator makes win2k (at least) lose the advanced tab under properties of ide channels. What this means is that there's no drop down menus to select pio or UDMA modes. Their silly utility lets you stare at a misconfigured device, but you have no ability to change it. Dang you intel.

It is for i8xx chipsets. When installed, those tabs are not needed, therefore are not seen. Are you saying if you mistakenly installed them on say, a BX board, it would allow the install and hide the tabs?
 
Unless I am mistaken I have an Intel 815E chipset, with graphics integrated onboard. I'm not sure however if it's the 815E or 815EM chipset, I'd have to install another utility from Intel to determine that.

Anyone actually tried installing the IAA? noticed any performance boost?

Nope, installed on a TUSL2. 815e or ep I believe. why are those tabs not needed anymore? I better do more reading of their specs page.
<edit> found the problem, didn't realize that the pio stuff was available as the little wrench in transfer mode limit... fixed, killer.
 
You do not set DMA/PIO mode with those tabs when IAA is installed. Those are for the MS IDE drivers. IAA does not use them. To check your DMA mode, use the IAA utility available from the strt menu.
 
I installed IAA under Windows XP Home and they go in and work fine. As far as speed, my rig was pretty fast before the IAA, so I can't really tell you, but if Intel updates their chipset driver, I am all over it.
 
I've tried running with and without IAA in my box a few different times. Only thing I can see is my boot times are around 3-5 seconds faster with IAA. I haven't had any particular problems with IAA either. I install IAA at the beginning of a fresh install. I've heard of some people having problems with this utility but usually when they're installing IAA after their OS has been running for a while.
 
I does speed up boot times for me. Game levels also load faster. MS Win2k IDE drivers are limited to ATA66. IAA runs ATA100. Not sure if this is true for XP.
 
I thought so too. HDTach burst is in the ATA66 range on my system (Win2K SP2). With IAA, it goes to ATA100 range <shrug>. How are you verifying ATA100?
 


<< How are you verifying ATA100? >>



1) Device manager>IDE/ATAPI Controllers>Primary IDE Channel> Advanced

2)HDTach
 


<< 1) Device manager>IDE/ATAPI Controllers>Primary IDE Channel> Advanced >>


Does not tell you ATA100 or ATA66.


<< 2)HDTach >>


What is your burst rate? Mine wont go over ATA66 unless I use IAA.
 


<< Device manager>IDE/ATAPI Controllers>Primary IDE Channel> Advanced >>



Is UDMA5 listed?
 


<< Mine says "Current Transfer Mode: Ultra DMA Mode" Nothing that specifies UDMA/2/4/5 when using MS drivers. >>




That's normal for Win2k,only Win XP show UDMA5.
 
Interesting. In XP can you get ATA100 burst speeds? I've tried, but can only get ATA66 speeds with Win2K SP2, but IAA gets me ATA100.
 


<< Interesting. In XP can you get ATA100 burst speeds? I've tried, but can only get ATA66 speeds with Win2K SP2, but IAA gets me ATA100. >>



That's even more interesting,I run Win2k sp2 also & without IAA i get burst speeds of over 80.
 
Hmm.. Ok, any idea how to fix mine? I have an i845 chipset board with 3.20 inf drivers, Win2K SP2, IDE set to DMA if available on a WD 1200JB. I get ~ 60 Meg burst with MS drivers and ~ 85 Meg with IAA. Is there a reg tweak or something to fix this?

Thanks!
 
For reference, using IAA and hdtach, I am over 80 on all my drives (2 ATA100 Maxtors and 1 ATA100 IBM). HDTach only displays up to 80, so I don't really know how close to 100 I am getting.

I'll check out the device manager properties when I get home and let you know how it reads. I have an i850 mobo.

EDIT - 1 of the maxtors is on the intel controller and the other 2 are on the hpt RAID controller. So, obviously, IAA only effects the intel controller, but it seems to be working properly.
