How can I know my mother board supports UDMA? My system manual only said that the connector is PCI bus IDE.<br />
<br />
I have another controller (Promise EIDE MAX disk controller).<br />
<br />
Do I still need another controller?<br />

How can I know my mother board supports UDMA? My system manual only said that the connector is PCI bus IDE.

I have another controller (Promise EIDE MAX disk controller).

Do I still need another controller?

Which motherboard do you have. I mean 430TX / VX etc.<br />
or 440 LX / BX. Look up your manual. If the manual doesn't<br />
explicitly state that your motherboard is UDMA compliant or<br />
supports UDMA it will not be able to benefit from the extra speed.<br />

my motherboard manual doesn't state that it's udma compliant.<br />
<br />
You said that it will not benefit from the extra speed, but if I install udma hard drive, it will still work right?<br />

Yes it will still work correctly. By the way the speed increase<br />
due to UDMA hard drive and compliant motherboard is purely<br />
cosmetic. It only increases the speed of the cached data of<br />
your hard disk. If you don't understand this don't worry. In simple words your computer will function properly.<br />

Do I need a special controller if I use UDMA Hard drive? What's the difference between IDE, UDMA, and ATA?<br />
