I have a Lenovo T60 laptop that gives a PXE-E05 error at boot time. Basically, this relates to something wrong in the PXE ROM. From what I can tell, fixing it should be easy (a simple firware flash of the PXE ROM) but the Intel PREBOOT (BOOTUTIL) package refuses to do it because it is an embeddded NIC :(
I have tried several versions of the BOOTUTIL utility but they all refuse with the same message.
Any ideas anyone?
