I was reinstalling Windows XP on a laptop , Upon loading the Serial ATA Drivers ( Via a floppy during setup ) and running the installation I was asked “insert the disk labeled Intel Application Accelerator driver into drive A” The Intel Application Accelerator driver uses AHCI for Native Hot Plugging a drive , which is something you are not going to hopefully need while installing windows. To stop this error message coming up I went into the BIOS and disabled AHCI for the windows Installation If this is not an option for you, you might have to go ahead and create another floppy with the needed intel application accelerator driver! Here is a RAR file with all the needed drivers Details on how to yourself : http://download.intel.com/support/chipsets/imst/sb/manual45_oem.pdf
