Controller for UDMA Hard drive

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

You don't need a special controller. If your Hard Disk is UDMA and
your motherboard supports UDMA you just have to connect them
the way it is normally connected.
UDMA is faster as it allows transfer rates of UPTO 33.3 MB/s
all others allow UPTO 16.6 MB/s

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.
or 440 LX / BX. Look up your manual. If the manual doesn't
explicitly state that your motherboard is UDMA compliant or
supports UDMA it will not be able to benefit from the extra speed.

my motherboard manual doesn't state that it's udma compliant.

You said that it will not benefit from the extra speed, but if I install udma hard drive, it will still work right?
Yes it will still work correctly. By the way the speed increase
due to UDMA hard drive and compliant motherboard is purely
cosmetic. It only increases the speed of the cached data of
your hard disk. If you don't understand this don't worry. In simple words your computer will function properly.
