How to make sure that Windows XP uses UDMA5 for my 3 HDDs connected to PCI E-IDE controller?

Hello!
How to make sure that Windows XP pro sp2 uses UDMA5 for my 3 HDDs
connected to Promise Ultra 100 TX2? Promise Ultra 100 TX2 bios shows
that all 3 HDDs are connected at UDMA5.
Best regards,

What do you mean?
My Windows XP used PIO for my DVD drives, although mainboard BIOS was
using UDMA2 for them!

Thank Rod for your reply!
How are my DVD drive and my HDD different in the issue?
Can Windows XP erroneously use another interface speed than the
Promise BIOS?

Win turns the DMA off when its getting significant numbers
of CRC errors to the drive, for the safety of your data.
The bios is irrelevant to the Win DMA setting.

Its not that so much as it sets the mode used
with drives that arent on a biosed addon card.

Thanks Rod for your explanations!
How are a biosed addon card and a mainboard different for Win? Why
does Win set the mode used with drives that are on a mainboard, not on
a biosed addon card?
If bios is irrelevant to the Win DMA setting, could Win use a
different mode that in the Promice BIOS?

Different drivers.
Why does Win set the mode used with drives that
are on a mainboard, not on a biosed addon card?

Its a lot harder to control what non MS driver does.
If bios is irrelevant to the Win DMA setting, could Win
use a different mode that in the Promice BIOS?

Depends on the driver for that card.

Thanks Rod for replying!
If possibility of Win using a different mode that in the Promice BIOS
depends on the driver for that card, how to make sure that Win uses
the same mode that in the Promice BIOS in my case?
Best regards,
Dima

Thanks Rod for your reply!
Why cann't Win use a different mode for drives connected to the
Promice card if Win can use a different mode for drives connected to a
mainboard?

Because that sort of card normally has its own drivers.

I clicked F6 during bootup from Windows XP CD and installed a driver
for the Promice card. I did not install a driver under Windows XP.
Windows XP SP2 stalled, redooted repeatedly if I did not install
driver during bootup from Windows XP CD.

Then its clearly got its own driver.
I did not install a driver under Windows XP.

Doesnt matter, you installed one before that.

Nope, it's not. Win usualy just uses the settings bios setup sets.
Its not that so much as it sets the mode used
with drives that arent on a biosed addon card.

Of which there is only one or two (biosless addon card).
Clearly he wasn't speaking of that.

Different drivers.
Duh.


Its a lot harder to control what non MS driver does.

Since when are mainboard included chips made by Microsoft.
Depends on the driver for that card.

And that of the MB included chipset as well.

Because that sort of card normally has its own drivers.

So do the MB included chipsets.
Main reason why newer motherboards/chipsets than Windows
distribution fail to install Windows by lack of driver.
