On Startup: Can't Get to Boot or SAS Configuration Interface

I have a T7600 with a PERC h310 SAS adapter, but I cannot get to the configuration interface to setup a RAID.

The system has a 256GB SSD boot drive, and I added five 3TB drives to setup a RAID 5. Unfortunately, the system only recognizes the boot drive and 2 drives.

On bootup, I first see an option to hit F12 for boot options - this does nothing

Next, I see hit R to run Configuration Utility - this does nothing

Next, I see a quick flash "Alert" and then F1 (can't read), F2 (can't read), F5? (can't read) - selecting any of these does nothing

Then windows starts up.

I have also tried C, as this got me to the configuration interface once, I think..., but does not work now.

Any ideas?
