Thanks for your additional informations and screenshots.
Now everything is clear for me and there is nothing to worry about for you.
Both XP installation methods you have tried are working fine and everything is running as it should.
The only difference between both Intel SATA AHCI Controllers, which are shown within the "IDE ATA/ATAPI Controllers" section of the Device Manager, is the name and nothing else. Both are doing absolutely the same and are using exactly the same driver (IASTOR.SYS dated 06/04/2009). You can verify this by looking into the driver details of both Controllers.
I will try to explain the details, which caused the irritations:
- During the first (=TEXTMODE) part of the XP installation Windows Setup detected and "installed" the only appropriate Controller named "Intel® ICH9 SATA AHCI Controller (added by Fernando)" with the HardwareID "PCI\VEN_8086&DEV_2923&CC_0106", listed within the TXTSETUP.OEM and IAAHCI.INF files of the Intel Matrix Storage Manager driver v22.214.171.1243. This happened in both cases (driver integration and F6 method).
- It was the text file named IBEXAHCI.INF (v126.96.36.1993 and dated 06/04/2009), which is part of the integrated Intel Chipset "driver" set, which renamed the Controller during the Hardware detection (=GUIMODE) part of the XP installation. Since the Intel chipset "drivers" were not present while installing Windows XP by using the F6/floppy method, no renaming of the Controller happened in this case.
By the way: AFAIK the renaming of the Intel AHCI Controller doesn't happen, if you install the Intel chipset "drivers" after having completed the XP installation.
- The "Property" tab entries of the "Intel® ICH9 Family 4 Port SATA AHCI Controller - 2923" are absolutely misleading, because the used driver is not v188.8.131.523, but v184.108.40.2063.
- At first view the identical driver dates are irritating, but I checked it: Both files, the real driver named IASTOR.SYS and the text file named IBEXAHCI.INF have been released at 06/04/2009.
Have fun with your XP installation and your SATA hdd running with the actual official Intel AHCI driver.
