P4C800E-Dlx and Intel Application Accelerator

[formerprof]

I am running two S-ATA and one P-ATA drives on the Intel controller in a
non-raid configuration. Is there any reason to use the Intel Application
accelerator in WinXP? Many thanks for your help -- good wishes to all.

IAA speeds up the performance of the motherboard by about 5%.

IAA is the old software used to provide bus mastering (DMA) to older
chipset IDE interfaces.

IAAR is the new RAID software for ICH5R or later Southbridge (WinXP
only). You use it if running a RAID application on the SATA ports of
the Southbridge. For running ordinary disk configurations, DMA modes
are already supported by Windows drivers, so IAAR is not needed.

In your case, you don't need either of them.

HTH,
Paul

Dear Paul,

Thanks so much -- the Intel documentation wasn't explicit on that point, so
I appreciate your expertise and clarity. All good wishes.

The Intel 875P chipset of your MB (and mine for that matter) is not
supported by the Intel Application accelerator, according to this page:

Jan, this later Intel document seems to be contra:

ftp://aiedownload.intel.com/df-support/7484/ENG/relnotes.htm

The question boils down to whether I need the driver for non-raid use of the
chipset. Thanks and all good wishes.

Hello formerprof,

No, the document you referred to is about the Intel Chipset Software
Installation Utility and that's not the same as IAA. Try to install the IAA
and you will be told by the installer that your chipset is not supported, In
other words: it will refuse to install on your system. You don't need IAA
either, because the chipsetdrivers for the 875P chipset are far more
sophisticated than the ones for the earlier chipsets that are supported by
IAA. So don't bother about it.

Cheers!
