Re: alternate kernel.
hpux ls
(lists possible configurations, I'd expect a "backup" or "last_install")
then:
hpux backup/vmunix
or whatever else is appropriate for your alternate configuration.

HP-UX Boot Loader for IPF -- Revision 2.028
Press Any Key to interrupt Autoboot
\efi\hpux\AUTO ==> boot vmunix
Seconds left till autoboot - 9
Press a key now!
Now boot the backup kernel.
HPUX> boot backup
Hope this helps!

Torsten.

Re: alternate kernel.
Booting from the EFI Shell
1.Access the EFI Shell.
From the system console, use the up/down arrow keys to select the ├в EFI Shell├в entry from the EFI Boot Manager menu to access the shell.
2.Access the EFI System Partition for the HP-UX boot device.
Use the map EFI Shell command to list the file systems (fs0, fs1, and so on) that are known and have been mapped.
To select a file system to use, enter its mapped name followed by a colon (:). For example, to operate with the boot device that is mapped as fs0, enter fs0: at the EFI Shell prompt. When you hit Enter to complete the command the shell prompt will change to reflect your device selection: (fs0:\>)
3.Enter HPUX at the EFI Shell command prompt to launch the HPUX.EFI loader.
If needed, you can specify the loader├в s full path by entering \EFI\HPUX\HPUX at the EFI Shell command prompt.
4.Allow the HPUX.EFI loader to proceed with the boot command specified in the AUTO file, or manually specify the boot command.
By default, the HPUX.EFI loader boots using the loader commands found in the \EFI\HPUX\AUTO file on the EFI System Partition of the selected boot device. The AUTO file typically contains the boot vmunix command.
To interact with the HPUX.EFI loader, interrupt the boot process (for example, type a space) within the time-out period provided by the loader. To exit the loader use the exit command
