How to make Burst on PCI bus?



Hi! Everyone.

I'm a newcomer on this mailing list.(I'm happy to be here)
Here goes the basic, very easy question.
In my understanding, for host-PCI bridge, the bursting is done automatically 
by hardware like host bridges. So the software programmer doesn't care about
from what words to what words will be written or read in burst.
I saw in LSI logic's PCI core manual that the PCI core monitors the address 
sequence and when the address is in increasing order, it converts the writing 
actions into a single burst. 
 Is my understanding right? (so called "combining actions")
Or is there any burst-making machine instruction in CPUs like Pentium?
Can we control the bursting of data  transfer explicitly in the application
S/W level?
Someone, Please answer to my question. Any comments are welcome.
