Dear Xavier,
Appreciation for your answer, I will use uclinux 2.6.19 with my tartget.
I am not familiar with linux, and i have no target board with uclinux. checking
linux sourceCode, I can find a defined macro "HD_IRQ" In file hd.c. so i
guess, the HDD must used interrupt wiht PIO mode, but i am not sure if
the INT pin on HDD side is pin31"INTRQ"

Hi Kevin,
Never tried the IDE bus connected to the 44B0X in DMA mode. But which uClinux
kernel version do you use with your target ? Is it a snapgear distro ?
