I guess there is a way but not easy.
Here are the steps.
– First make sure your WSI environment works and pushes out the correct and working firmware
– open the broken and one working unit
– locate the BIOS chip (small socketed chip with appr 1,5cm square)
– unplug the BIOS chip in both units and swap the working one in the broken unit
– start the WSI imaging process
– when the PXE request went through and imaging is about to start, press “Pause”
– now unplug the working BIOS chip while the unit is running (sounds strange but I did that several times without loosing one unit)
– plug in the broken one in the broken unit
– press any key to continue the imaging process
After that all should be well.
