UsingtheEFIShelltoManuallyBootYourSystem

TousetheEFIshelltobootyoursystem:

Procedure22BootingfromtheEFIShell

1. AccesstheEFIShell.

3. EnterHPUXattheEFIShellcommandprompttolaunchtheHPUX.EFIloaderfromthecurrentlyselectedbootdevice.

Ifneeded,youcanspecifytheloadersfullpathbyentering\EFI\HPUX\HPUXattheEFIShellcommandprompt.

4. AllowtheHPUX.EFIloadertoproceedwiththebootcommandspecifiedintheAUTOfile,ormanuallyspecifythebootcommand.

Bydefault,theHPUX.EFIloaderbootsusingtheloadercommandsfoundinthe\EFI\HPUX\AUTOfileontheEFISystemPartitionoftheselectedbootdevice.TheAUTOfiletypicallycontainsthebootvmunixcommand.

TointeractwiththeHPUX.EFIloader,interruptthebootprocess(forexample,typeaspace)withinthetimeoutperiodprovidedbytheloader.ToexittheloaderusetheexitcommandthiswilltakeyoubacktoEFI.

AdjustingtheAutobootDelay

Bydefault,theautomaticbootdelayissetto10seconds.Youcanchangethisvalue:

Example21SettingtheautobootdelayusingtheEFIBootManagersBootOptions:

1. SelectBootOptionMaintenanceMenufromthebootmanagersmainmenu.

2. SelectAutoBootTimeOutfromthebootoptionmaintenancemenu.

3. SelectSetTimeOutValue.

4. Enterthenumberofsecondsyouwanttouseforthebootdelay(forexample30).

Example22SettingtheautobootdelayusingtheEFIShellsautobootcommand:

Tosettheautobootdelayto30seconds,usetheEFIShellcommand:
