This allows for faster, more consistent configuration of multiple computers. procedures require a diskette drive or a supported USB flash media device, such as an HP ✎ Both Drive Key. Copying to Single Computer Ä CAUTION: A setup configuration is model-specific.
Desktop Management Copying to Multiple Computers Ä CAUTION: A setup configuration is model-specific. File system corruption may result if source and target computers are not the same model. For example, do not copy the setup configuration from a dc7nnn PC to a dx7nnn PC. This method takes a little longer to prepare the configuration diskette or USB flash media device, but copying the configuration to target computers is significantly faster.
Desktop Management Creating a Bootable Device Supported USB Flash Media Device Supported devices have a preinstalled image to simplify the process of making them bootable. All HP or Compaq and most other USB flash media devices have this preinstalled image. If the USB flash media device being used does not have this image, use the procedure later in this section (see “Unsupported USB Flash Media Device”). To create a bootable USB flash media device, you must have: Ä ■ A supported USB flash media device.
Desktop Management 10. At the A:\ prompt, enter FORMAT /S X: where X represents the drive letter noted before. Ä CAUTION: Be sure that you have entered the correct drive letter for the USB flash media device. FORMAT will display one or more warnings and ask you each time whether you want to proceed. Enter Y each time. FORMAT will format the USB flash media device, add the system files, and ask for a Volume Label. 11. Press Enter for no label or enter one if desired. 12.
Desktop Management 6. Go to Advanced > PCI Devices to disable both the PATA and SATA controllers. When disabling the SATA controller, note the IRQ to which the controller is assigned.
