PXE and new Bios of latitude

Question

Hi

With the last version of Bios on differents latitude computer, the network pxe boot don't work anymore :

The new bios update always the Intel Boot agent (OROM) from 1.3 to 1.5.38.1 .

Our server is Windows 2008 (dhcp,pxe,Distribution point) with SCCM 2012.

To go back to oldest version resolve the problem (Ex latitude E6420 Bios 19 to 17).

Have ou any idea?

Thanks

If you ordered your new Latitude system with Windows 8, it will be in UEFI mode.  Your PXE on Windows 2008 may require the system to be reverted to Legacy mode in the BIOS.

This exact issue happens on the T3600 with A12 with Intel PXE firmware 1.5.38.1. If you downgrade to A11 which includes 1.5.38, the problem goes away.
