As such, I use the manual path: - On a machine (or VM) running the latest CentOS 8 kernel: * Download the relevant DUD source RPMs ( https://elrepo.org/linux/elrepo/el8/SRPMS/) and unpack them. (E.g. https://elrepo.org/linux/elrepo/el8/SRPMS/kmod-megaraid_sas-07.717.02.00-1.el8_5.elrepo.src.rpm ) * From the module directory, manually build the missing kernel drivers by hand. (if you don't know what to do, follow the commands in the %build segment in the DUD spec file) and save the resulting .ko kernel modules (E.g. megaraid_sas.ko, isci.ko, etc). - Start the machine(s) using the CentOS8 stream installation USB. Wait for the first screen but *don't* do anything. - Switch to a console (Ctrl-Alt-F1). - Start the network and scp the newly built kernel modules into /lib/modules/$(uname -r)/extra - Load the newly copied kernel module using insmod. (E.g. insmod /lib/modules/$(uname -r)/extra/megaraid_sas.ko) - Check the kernel log (via dmesg) and make sure the storage controller has initialized correctly. - Switch back to the anaconda installer (Ctrl-Alt-F6 or F7). - Continue installation as usual. * (* I think I had to manually copy the kernel module to the newly installed machine, and dracut -f to get it included in the initramfs image, but I'm not certain). - Gilboa
