I'm trying to build an old PowerEdge R715 server with Redhat 8.

I tried 8.1 and 8.3 DVDs: both tell me there are no disks.

Redhat 7.9 sees the disks.

BIOS is currently at 3.2.2 and I just updated the H700 controller firmware to 12.10.7.

Is there a driver available?  I looked in various places online and also at https://www.dell.com/support/home/en-us?app=products.

Thanks!!
