This is the patch for VT8251 AHCI Driver.

Important notes:
 1. This patch is based on source files of Fedora Core 4 
     <linux-kernel-src>/drivers/scsi/ahci.c
 2. In the bin directory, there are two pre-compiled modules, one for SMP system,
    one for UP system.

How to apply the patch:
 1. copy the ahci.c.patch to <linux-kernel-src>/drivers/scsi/
 2. patch  < ahci.c.patch
 3. rebuild the modules

How to test the patched driver:
 1. After rebuilding the patched source file, we can get the module file: ahci.ko
 2. Or we can use the pre-compiled binary files in the package.
 3. Login the running Linux system as root user.
 4. Remove the old ahci module by using: #rmmod ahci
 5. Install the new ahci module by using: #insmod ./ahci.ko
 6. Now can access the SCSI disk device /dev/sd#
