Apple Event: May 7th at 7 am PT
My Mac Pro inoperable -- I have been trying to fix the problem by using command R and variations thereof to no avail finally opened firmware and submitted a new password but on restart I cannot insert the password because my mouse has frozen!
The Mac Pro silver tower does not have Internet Recovery in its ROM, and unless it has the original factory drive that has NEVER been erased, it has lost the diagnostics directory as well.
So the use of Recovery depends on having a viable 'Recovery HD' partition on a working drive.
The solid Apple is only seen after it is loaded from a drive after a cold start, or upon Re-Start from the same drive. So seeing the solid Apple says the drive is working well enough to get the first 'blob' of software off it and into memory.
The simplest thing your Mac can do is respond to holding Option at startup. This invokes Startup Manager (whose code is all in ROM) which over the span of about five minutes will attempt to discover, by brute force, every potentially-bootable Volume and give you a chance to select one and boot from it.

Silver tower --
Which model year? 42 lb silver tower? dark cylinder, or something else entirely?
Thank you Grant. I have used the Option start method and started with an external drive.
