IAA: Really needed?

Postby glock20rocks on Sat Dec 14, 2002 2:25 pm

I have an Intel i845 based mobo (Abit BD7-RAID). I have the chipset drivers installed, and DMA is enabled on all channels. Is the IAA really needed then?

Nope.

i don't know what you mean by "chipset drivers".
basically, IAA is one of the drivers for the motherboard (for any Intel chipset based mobo) - for the IDE controller.
apart from any other driver, it is supposed to boost performance (or so claim Intel), so you might want to check up on that, to see if performance with IAA installed is any better than with the default MS IDE drivers installed by the OS.

In some cases IAA limits or blocks CD/DVD devices for digital audio extraction...

dodecahedron, there are two Intel drivers for i845 chipsets, one if Intel INF which is for all Intel chipsets, and one is IAA, which is only for i845 and i850 I think.
The later does improve performance a bit, just a bit, but brings some problems. DMA is not under user controll anymore, it is controlled by IAA and you cannot change it manually. This sucks. But other than that and a few minor problems, IAA is OK.
Not necesary but sometimes better than MS drivers.

as far as i know, the IAA is for ALL motherboards with an Intel chipset.

when the IAA came out Intel made a big hoola about how it improves performance by so and so %...turned out to be nothing all that great...just another IDE driver...

The IAA is not for all Intel chipsets, but supports from the 810 through the 860 chipsets.

OK, i stand corrected.

i guess i should've said "all _recent_ Intel chipsets"...
