When you try to install Windows Vista on a portable computer that uses an ATI SB600 Series chipset, each driver may take a long time to install. Therefore, the Windows Vista installation process may take several hours.

This problem occurs only on a computer that uses a Serial Advanced Technology Attachment (SATA) device that is operating in Advanced Host Controller Interface (AHCI) mode. This problem does not occur if the SATA device uses SATA Combined mode or Parallel Advanced Technology Attachment (PATA) mode.
