Error 0xC0000001 vmxnet3 with WinPE 4 and ESXi 5.0.0 U2

Hi, 

I get the Error 0xC0000001 When loading the boot image with vmxnet3. The ESXi has been updated to 5.0.0 u2 so this bug should be solved.(http://www.vmware.com/support/vsphere5/doc/vsp_esxi50_u2_rel_notes.html). With E1000 the image boots sucesfully and the drivers where imported from the Driver folder of the vmware tools folder in program files. 

I have seen few articles about the MaxTFTBlockSize and RamDiskTFTPBlockSize but didn't find the default.bcd in the RemoteInstall folder. And no confirmation that the registry still apply. 

Our setup is one standalone SCCM2012 SP1 with DP and MP on the same machine (2008R2SP1). 

Thanks for your help

Philippe
