Silent Installation


  • Resolves issue with Hood Sensor not reporting an error if an Administrator password is set in F10 Setup.
  • Resolves issue with some PCI - Cardbus bridge cards not loading the "Generic Cardbus Controller," which resulted in the driver for the controller having an error condition in Windows XP.
  • Corrects an issue with USB 2.0 devices being visible in the OS when connected to the front USB ports even though the front USB ports have been disabled or hidden in F10 Setup.
  • Corrects BIOS F10 Setup's Italian Storage Menu for Hard Drives, which was not displaying the complete text.
  • Updates PXE ROM to version 6.3.0. This ROM fixed a PXE boot failure that occurred with some PXE servers where the "DHCP boot filename" option (OPTION 67)was manually added. Also the base code was fixed so that the provided length field file name strings are used to nullify the filename that is used for TFTP/MTFTP download.
