PXE enablen op een slimme manier?

[-Nexus]

Ik ben bezig met ZEN voor mijn stage,
Ik schrijf enkel de procedure, gelukkig maar want er zijn 3000 clients waar het op moet komen.
De 3000 pc's zijn Dell computers varierend van optiplex 110 t'm 280
helaas vereist ZEN preboot services (PXE) om te kunnen imagen, en die instelling moet dus op iedere pc in de bios, bij integrated periphels aangezet worden, is hier een snelle manier voor?
zal er bij iedere pc langsgelopen moeten worden?
ik weet dat dell bios flashen over het netwerk ondersteund, maar ik verwacht dat je daar PXE voor nodig hebt.
Ik hoop dat jullie tweakers er iets van weten,

Wat draait er nu op die systemen?? Kun je remote niet Dell Openmanage installeren, daarmee kun je volgens mij ook PXE aanzetten..

Dank voor de snelle reply!
ik zocht blijkbaar op de verkeerde termen...

verder ook een vbscript die t zou moeten kunnen, maar ik ga voor de openmanage client...

' COMMENT: Can be used to set any BIOS setting.  Basic
' Progression of the script:
'
' Verify OMCI 6.1 or 7.0 is installed
'
' Check to see if the BIOS password is enabled, and the validate the password
' with the credentials supplied by the strBIOSPassword variable if needed
'
' Executes the BIOS setting.  This script can easily be used as a 
' template to change any BIOS setting, not just PXE.  The values that must
' change for alternate BIOS settings are strBIOSSettableProperty, And
' intBiosSettingValue.
'
' The script will exit on any errors and log the failure in the 
' appplication event log and a log file in the root directory.
'
' The script will log success in the appplication event log and a 
' log file in the root directory

Ik vind dit meer iets voor Software Algemeen Zit toch meer in de softwarematige kant dan de verbindingstechnische
