Hi, how to increase the time for F12 intervention when pxe boots prompt to press F12 key before PXE Exists ( in pxe conf mgr i have increased the pxe response delay & its not helping ) I came across this link to disable the F12 intervention & its work fine, but I wanted to increase the time of F12 before PXE exists. http://social.technet.microsoft.com/Forums/en/configmgrosd/thread/1f586944-f4a6-4be6-a4f7-c457c1a81e8d

Hi, I believe it's a bios settings but it's not configurable on all bios, the settings you configured in pxe conf mgr is to allow other PXE server to answer first before SCCM replies. may i ask why do you need it for?

As Avi said, it should be in the bios. The PXE response delay is how long your pxe service points decides to wait before responding to a pxe request. You will change this setting only if you have multiple pxe service points and you want to stagger them in some way in case one of the points gets busy so the other will respond instead. Check in your bios for the client, if you can't change the boot option start up time, you'll at least be able to manually change the device for boot option for network if catching F12 is hard to do. Or you can just hold the F12 button when booting?

once F12 prompts appears it will immediately exists after 3seconds, so wanted to see if there is any option to increase from SCCM. Avi & Peter replies tells that its not controlled from SCCM.

you take a look on your SCCM Console > Site Management > Site Settings > Site Systems > locate your server with PXE Role > right click on properties for ConfigMgr PXE service point > General Tab, check the lower part "Specify the PXE server response delay" .. im using R3
