Thank you for your reply.

Really ?
Let me make sure :
* To invoke burst-read on PCI, I have to use DMA (or busmaster capable
PCI device) rather than accessed by CPU.
Is this right ?

I'm sorry missing our environment about chipset in last mail.
Our environment is :
MB : Asus P2B (Intel 440BX chipset)
CPU : Pentium-II/400MHz

Thank you.
