Here we use RIS to build machines. It has been successful.
Some F series RM machines refuse to build using RIS due to an issue with the BIOS - so we hand build them and then update the BIOS.
Anyway - I've just taken a call from the technician telling me that hand built machines perform a lot better than RIS built machines. I'm quite happy with RIS - it works.
Is this the case or shall I send him around the school to rebuild every machine manually so we can see the performance increase he claims there is :-)
