Accessing the Removable Media Devices Using EFI

2.Make a list of all device connections so you can reconnect them after the installation is completed.

3.Disconnect all mass storage devices from all controllers except the boot controller.

4.Configure the boot controller and boot drive.

NOTE: If you are using an HP SmartArray controller, see the Controller's User Guide. You can interrupt the boot process to invoke the EFI-based SmartArray configuration utility, ORCA. To invoke this utility press F8 on the VGA console or Esc–8on the serial console.

Accessing the Removable Media Devices Using EFI

When hardware (for example, a hard disk drive, a USB Hard Disk Drive (HDD) device, or a CD or DVD drive) is added to a system after the system has booted to EFI, the EFI shell environment does not automatically detect the new device. You must reconnect the device driver for the EFI shell to recognize the device.

Additionally, the EFI shell environment creates default mappings for all the device handles that support a recognized file system. After you change the system configuration or add a new device, you must regenerate these mappings.

Enabling a CD/DVD Device

To access a CD/DVD, you must enable the EFI shell to detect it, and then access it using the following steps:

1.From the EFI shell, enter the following:

Shell> reconnect -r

The reconnect command reconnects one or more drivers from a device, disconnecting all the drivers from all the devices and then reconnecting them. If a device handle is not specified, the reconnect operation is performed on all the handles in the system. If a device handle is specified, only the device handle and the devices below it are reconnected.

2.Regenerate all mappings:

Shell> map -r

The -roption regenerates all the mappings in a system. The EFI shell displays a device mapping table similar to the following example:

fs0 : Acpi(PNP0A03,0)/Pci(20)/Ata(Primary,Master)/CDROM(Entry1)blk0

: Acpi(PNP0A03,1)/Pci(10)/Scsi(Pun0,Lun0)blk1 : Acpi(PNP0A03,0)/Pci(20)/Ata(Primary,Master)blk2 : Acpi(PNP0A03,0)/Pci(20)/Ata(Primary,Master)/CDROM(Entry1

TIP: The map command displays or defines a mapping between a user-defined name and a device handle. The most common use of this command is to assign drive letters to device handles that support a file system protocol. After these mappings are created, the drive letters can be used with all the file manipulation commands. It can also be used to create new mappings and delete existing mappings using the -doption. If the map command is used without any options, all the current mappings are listed. If the -voption is used, the mappings are shown with additional information on each mapped handle.

3.Record the device name of the CD/DVD device, fs0, in this example. Use this device name to explore the contents of the removable media.

4.Go to the CD/DVD file system:

# fsnumber:
