Hey B-Thunder and Cap-T-OU We ran into similar problems but a colleague figured out how to install the ICH9 drivers. A little background..... - New Dell Optiplex 775's arrived and we have an image (XP SP2) to install so there's no room for F6 (although that doesn't seem to install them) - we have a config tool that is unique for each model of computer.....it installs all missing drivers and for those with SATA controllers we've successfully used the "Intel® Matrix Storage Manager" install script which looks like this: rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 132 %~dp0imsm_pre.inf This script didn't work for the 775 and neither did using Device Manager Wizard......so you have to "force" the installation of the ICH9 driver. - Ensure in BIOS, the HDD is set for Legacy mode - Open Device Manager - Open IDE ATA/ATAPI controllers - Select the "middle" occurance of the Standard Dual Channel PCI IDE Controller To ensure you have the right one, open the Properties and look at the "Location"....it should appear as: PCI Bus 0, device 31, function 5 - Once you have the right device select the Drivers tab - Select Update Driver - Choose radiobutton "Install from list or specific....." Next - Choose radiobutton "Don't search. I will choose ....." Next - Select Have Disk - browse to the path where you have stored the Intel Matrix drivers - Choose the ICH9 SATA AHCI Controller driver Next - You'll see a message telling you that this driver is incompatible or it doesn't match ...whatever select the button to complete the install (Next or Finish) .....sorry but I don't have this in front of me.... - Reboot the computer and in the BIOS change the HDD to RAID ACHI and this should give you the needed SATA controller driver for the Optiplex 755 Good luck S
