SCCM WinPE task sequence failure

[groupers]

I know this is an old thread but I'm running into the same issue. I work in a large environment and if we PXE boot with the Intel OpROM there are no issues. On certain model computers (HP EliteBook 8540p, 8570p that I know of) no matter which task sequence is chosen once booted into SCCM, the 0x80004005 error appears. This does NOT happen on HP dc7800 desktops... I haven't had time to test other models.

Did you have any luck solving this? The SCCM installation hasn't been modified for iPXE, this is just running standard SCCM TFTP PXE boot with iPXE when we experience the issue.
