2. At the EFI Shell environment, issue the acpiconfig command to list the current ACPI
configuration for the local nPartition.
On cell-based HP Integrity servers, to boot the HP-UX OS, an nPartition ACPI configuration
value must be set to default. If the acpiconfig value is not set to default, then HP-UX
cannot boot; in this situation you must reconfigure acpiconfig or booting will be
interrupted with a panic when launching the HP-UX kernel.
To set the ACPI configuration for HP-UX:
a. At the EFI Shell interface enter the acpiconfig default command.
b. Enter the reset command for the nPartition to reboot with the proper (default)
configuration for HP-UX.
3. At the EFI Shell environment, issue the map command to list all currently mapped bootable
devices.
The bootable file systems of interest typically are listed as fs0:, fs1:, and so on.
4. Access the EFI System Partition for the device from which you want to boot HP-UX (fsX:
where X is the file system number).
For example, enter fs2: to access the EFI System Partition for the bootable file system
number 2. The EFI Shell prompt changes to reflect the file system currently accessed.
The file system number can change each time it is mapped (for example, when the nPartition
boots, or when the map -r command is issued).
5. When accessing the EFI System Partition for the desired boot device, issue the HPUX command
to initiate the HPUX.EFI loader on the device you are accessing.
The full path for the loader is \EFI\HPUX\HPUX.EFI. When initiated, HPUX.EFI references
the \EFI\HPUX\AUTO file and boots HP-UX using the default boot behavior specified in
the AUTO file.
You are given 10 seconds to interrupt the automatic booting of the default boot behavior.
Pressing any key during this 10-second period stops the HP-UX boot process and enables
you to interact with the HPUX.EFI loader. To exit the loader (the HPUX> prompt), enter
exit (this returns you to the EFI Shell).
To boot the HP-UX OS, do not type anything during the 10-second period given for stopping
at the HPUX.EFI loader.
