Cannot get into bios! rx4100

I press del or f2, says its going to go into there but does not, continues to load bootchain of raid, pxe, and then EFI shell.

this is really getting annoying - aledgedly support number’s data base for the product is down and they will call me in 2 hours - 6 hours ago.

So, i was able to get into the bios once, if I hold down the restore thinger it boots windows - we just installed server 2012 r2 on it. but what the **bleep**!? I should be able to get back into the bios and change boot options.

Try the keyboard in the front usb port

did that, 

when pressing del of f2 the post screen says entering bios - but does not actually get there.

What happens if you slide all the drives out?

And just curious, why do you need to get into it.
