Hello everybody:
I want to develop a simple AHCI bus driver. It can enumerate different storage devices and can recevice special commands from systerm function driver or storage lower filter driver. I can not predict the difficulty and workload of this work. Is there
anybody has this experience ?

Vista+ already has AHCI in-the-box, and the source is provided in WDK. Port it from ATAPORT back to SCSIPORT to make AHCI driver for XP.

Thank you for your kindly reply!
In fact, I need sent SCSI commands to hardwares that may cause hard can not work poperly.
And I can not sure if microsoft’s inbox drivers (Such as msahci.sys , atapi.sys) can support these commands. The following structure is the new design in my mind.
|| App1 || App2
|_ |
|_______| My Function Driver |________| My Function Driver
| |
|| My AHCI mini-port driver (And new commands supporting)
|
|| Microsoft ACPI driver
|
|_______| PCI Bus driver
