Hello, I am trying to add a Intel® 82801GR/GH SATA AHCI Controller (Desktop ICH7R/DH) to the mass storage options on my sysprep image to add support for a HP XW4400, I copied iaahci.cat, iaahci.inf, iastor.cat, iastor.inf, iastor.sys, and txtsetup.oem to the c:\windows\inf directory, and added [sysprepMassStorage] PCI\VEN_8086&DEV_27C1&CC_0106=c:\windows\inf\iaahci.inf ; Intel® 82801GR/GH SATA AHCI Controller (Desktop ICH7R/DH) PCI\VEN_8086&DEV_27C5&CC_0106=c:\windows\inf\iaahci.inf ; Intel® 82801GBM SATA AHCI Controller (Mobile ICH7M) PCI\VEN_8086&DEV_2652&CC_0106=c:\windows\inf\iaahci.inf ; Intel® 82801FR SATA AHCI Controller (Desktop ICH6R) PCI\VEN_8086&DEV_2653&CC_0106=c:\windows\inf\iaahci.inf ; Intel® 82801FBM SATA AHCI Controller (Mobile ICH6M) PCI\VEN_8086&DEV_27C3&CC_0104=c:\windows\inf\iastor.inf ; Intel® 82801GR/GH SATA RAID Controller (Desktop ICH7R/DH) PCI\VEN_8086&DEV_24DF&CC_0104=c:\windows\inf\iastor.inf ; Intel® 82801ER SATA RAID Controller (Desktop ICH5R) PCI\VEN_8086&DEV_25B0&CC_0104=c:\windows\inf\iastor.inf ; Intel® 6300ESB SATA RAID Controller PCI\VEN_8086&DEV_2652&CC_0104=c:\windows\inf\iastor.inf ; Intel® 82801FR SATA RAID Controller (Desktop ICH6R) My image is still blue screening, any ideas? I know this isn't a hal issue, as i use the Advanced Configuration and Power Interface (ACPI) PC", ACPI PIC HAL (Halacpi.dll) on the base image and use a script to copy the right hal in. any ideas? Thanks in advance. sysprep.txt Not sure why the attachment is comming out that way, i uploaded it twice, I assure you wordwrap is off, and it doesn't look that way in the inf iy you save as and open in notepad it looks fine.
