1. Introduction



Ascomputertechnologyhasadvanced,theBIOS(BasicInput/OutputSystem)has

expandedinanefforttohandlenewcomponents,largerandmorecomplex

chipsets,add‐incards,andsoon.ThisexpansionoftheBIOShasmadeit

increasinglyintricate.



Thecomputerindustry’sanswertoaddressBIOSlimitationsisthedevelopment

oftheExtensibleFirmwareInterface(EFI).EFIisasetofmodularinterfacesthat

replacesthesetoftraditionalBIOSinterfacesbetweentheoperatingsystemand

platformfirmware.



EFIisbasedonthehigh‐levelClanguageandisdriver‐based,scalable,andeasyto

debugandupgrade.EFIusesamodular,platform‐independentarchitecturethat

canperformbootandotherBIOSfunctions.



Tappingintothistechnology,HPhasimplementedaprebootpartitiononallofits

commercialnotebookcomputers.1AlongwithreplacingthetraditionalBIOS

interface,theHPpartitionaddstoolstotheprebootsystemenvironment.The

partitionisviewableontheharddriveandislabeledasHP_TOOLS.On2008and

latercommercialnotebookplatformswiththeEFIBIOS,HPcreatedthepartition

asaFAT32partition,duetoEFIBIOSlimitationswithaccessingotherpartition

formats.





2. Supported Platforms



TheHP_Toolspartitionfeaturedescribedinthisdocumentissupportedby2008

and2009HPbusinessnotebooks.



3. Location of HP EFI and Preboot Applications- the

HP_TOOLS Fat32 Partition



3

HPEFIapplicationsandprebootapplicationsprovideextensiveprebootfunctions

tothesystemBIOSresidingintheflashrom.TheseHPprebootapplicationsare

placedonaHPspecificpartition.On2008andlatercommercialnotebook

platformswithEFIBIOS,theprebootpartitionHP_TOOLSiscreatedbythe

preinstallteamasaFat32partition.

Warning

DonotencryptHP_TOOLSpartitionusingsoftwareencryptionprogramssuchas

WindowsBitLockerorFullVolumeEncryptionforHPProtectTools.Whenthe

partitionisencrypted,HPprebootapplicationscannotfunction.

Volume Name

HP_TOOLS

Note:QuickWebisaLinuxbasedapplicationandLinuxdirectoryiscasesensitive.

(SoisNTFS.Fat32isnot).WhenVolumenameandHewlett‐Packarddirectoryis

created,pleasemakesurethatit’sallcapitalized.

HP_TOOLS Partition Size

Thetotalpartitionsizeis2GB.



4. HP_TOOLS Partition Directories and Descriptions



TheHP_TOOLSpartitionstructureshouldmirrorwhatwealreadyhaveforNTFS

filesystem.AndtheEFIapplicationandprebootapplicationinstallationshould

followtherulesforotherHPsoftware.

Forthoseprebootdeliverablesthatarewebreleased,theyneedtobeinstalled

usingSoftpaq.

WhenaSoftpaqisrun,itwillextractintotheC:\swsetupdirectoryjustasother

Softpaqs.ThentheprebootsoftwareinstallationshouldsearchfortheFat32

partitionwiththe“HP_TOOLS”labelandinstallitselfunderthedirectory:

:\HEWLETT‐PACKARD\softwarename

e.g.Quicklook.efianditsdigitalsignatureshouldbeplacedunder

:\HEWLETT‐PACKARD\QUICKLOOK\quicklook.efi



5. EFI Power Management



ThereisnopowermanagementunderEFIshell.Therewillbesomethermal

management.



6. How BIOS Launches EFI and Other Preboot

Applications



For HP Signed Preboot Applications

TheHPsignedprebootapplications;theexecutablefileandthe

“filename.sig”signaturefilearestoredinthesamesubdirectory.

Incurrentimplementation,therearehotkeys(notedbelow)definedforHP

certainprebootapplications.



isusedtolaunchtheQuickLookEFIapplication.Thisbuttoncanlaunch

QuickLookfromS5,S4.BIOShasanoptiontodisabletheQuickLook

launch.Ifdisabled,pressingthebuttondoesnothing.



F2 isusedtolaunchtheDiagnosticEFIapplicationduringPOST.F2willnot

wakethesystemfromS5orS4.ItcanonlybepressedduringPOST

whentheBIOShotkeysareondisplay.

 isusedtolaunchtheQuickWeb.ThisbuttoncanlaunchQuickWebfrom

S5andS4.BIOShasanoptiontodisabletheQuickWeblaunch.If

disabled,pressingthebuttondoesnothing.



Note:ThesehotkeyswillonlylaunchthedesignatedsignedHPEFIandpreboot

applications.PleasecontacttheBusinessNotebookBIOSteamtodefineand

assignahotkeyforaspecificEFIapplication.



7. Preboot Security Requirements



Signed Preboot Applications



Whenaprebootapplicationislaunched,ithasasmuchcontrolofthesystem

resourceastheBIOS.Sincetheseapplicationsresideonthepublicharddrive

partitionwhichareeasilyaccessibleandthushacked,it’snecessaryforBIOSto

onlylaunchHPsignedprebootapplications.

Additional F10 Policies for Preboot Environment



BIOSF10providesseveralpoliciestocontroltheavailabilityofBootfromEFIFile

optionintheBootManagerwhenF9ispressed(fordetails,seeHowEFILaunches

EFIApplications)

SystemConfiguration‐>DeviceConfigurations

UEFIBootModeEnable/DisableDefault:Disable

ThispolicycontrolswhethertheBIOSallowstoboottoanEFIfile.Forsecurity,

it’srecommendedtobedisabled.

WhenUEFIBootModeisdisabled,the“BootfromEFIFile”optionwillnotshow

upintheBootManagerwhenF9ispressed.Insuchacase,theonlywayto

launchHPEFIapplicationsistousethehotkey.

CustomizedLogoEnable/DisableDefault:Disable

TheEFIBIOSprovidesthenicefeaturefortheusertocustomizethelogo

displayingduringtheboot.Thelogoisabitmapfilethatacustomercan

add/changeontheHP_TOOLSpartition.

SinceBIOScan’tcheckthesignatureofthecustomizedlogobitmapfiles,itmay

beusedasanattacktooloftheBIOSpostprocess.Thusanoptionisneededto

disablethiscapabilityforthehighlysensitivesecurityenvironment.

HPQuickLookEnable/DisableDefault:Enable

TheEFIBIOSprovidesthefollowingpolicytocontroltheavailabilityofthe

QuickLookapplicationoption.

HPQuickWebEnable/DisableDefault:Enable

TheEFIBIOSprovidesthefollowingpolicytocontroltheavailabilityofthe

QuickWebapplicationoption.
