Links to the related FESCo items are in https://www.phoronix.com/news/Fedora-41-Switch-DNF5-Approved but in short, RHEL10 needing to branch off Fedora 40.
You can find the 7.12.x support CD for that controller at https://www.ibm.com/support/pages/ibm-serveraid-software-matrix. I'm pretty sure that server model did not support USB booting so you'll need to burn that to a disc. This will be the disc to boot off of to create your array(s).
I forget if the support CD had the application you would install in Windows to manage things after installation or not, or if that's only on the application CD. Either way you'll find several downloads for various OS drivers and the applications from that matrix.
To redeem some of it, there seems to be good support for further blacking out r/gaming. Can't fault the mods for coming back after 2 days like they said they would, but they should have thought that through a bit more from the start.
