Do you know if it is in CMOS or FLASH? I could not tell.
If in CMOS it's trivial to script and they're going to want that script, because in the typical factory BIOS these settings have a way of "reverting to default", which is why we once had 4600 nodes come up and want a keyboard to be attached; they forgot that we'd told them there were no keyboards. ... and those are hardly the only nodes we've seen the problem on over the last 10 years.
