HP 8440p 開AHCI

不好意思~跟板上各位請教一下，先謝各位幫忙！

我的目的是要在安裝完XP SP3上從IDE Mode改AHCI Mode，
爬了很多文章，一直改不起來，之前改dv2224tx都沒可以，
我修改的方式如下：

=======================================================================
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\PCI\VEN_8086&DEV_3B22&CC_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
"0"="PCI\\VEN_8086&DEV_3B22&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA"
"Count"=dword:00000001
"NextInstance"=dword:00000001

=======================================================================

其中兩行我從Intel的Driver試了好幾個都不行，一樣無法修改，
PCI\VEN_8086&DEV_3B22&CC_0106
"PCI\\VEN_8086&DEV_3B22&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA"
不知道是我弄錯了嗎？下面是Intel Driver秀出來的資訊，我應該要怎麼修改我的reg file?

還有一個問題，不知道板上是否有人發現在IDE Mode都是跑DMA 0，
HDD跟DVD都是一樣，現在用起來硬碟速度不是很好，這是正常的嗎?
Intel INF已經更新，就差AHCI開啟！
