Would it be possible to build an ISO for PPC64 Big Endian ? I could build with a cross compiler environment. Can you set directions for what I need for PPC64 Big-Endian ? ---

Building an ISO would not solve this for you. The entire power build of Rocky Linux 9 is all ppc64le. Because of this, there is no support for big endian. Supporting big endian would require a full new build of Rocky Linux 9. ---

That’s what I plan on doing, an entire power build of Rocky Linux 9 for ppc64BE and then once that’s complete an ISO build. I was just wondering if you have the flags handy and the source tree for the ISO. Once I get the initial build installed on my old p720 I can build the new releases on my p720. I guess I wasn’t clear enough when I posted. I know cross compile works. I just never made bootable media for the PowerPC with an Intel based machine. I wasn’t sure if that worked. ---

This won’t be as simple as you want it to be. Kickstarts don’t generate our minimal nor our DVD images. To make a bootable image, you need you need to run `lorax` on a native system that would have access to the necessary repositories that have the needed packages to build that image ([template](https://git.resf.org/sig_core/toolkit/src/branch/devel/iso/empanadas/empanadas/templates/buildImage.tmpl.sh)). Once the boot image is made, you would need to use [xorriso](https://git.resf.org/sig_core/toolkit/src/branch/devel/iso/empanadas/empanadas/templates/buildExtraImage.tmpl.sh) with a [dialog](https://git.resf.org/sig_core/toolkit/src/branch/devel/iso/empanadas/empanadas/templates/xorriso.tmpl.txt) to take the boot image and add in the extra repositories and packages for anaconda to utilize. That can be done on any architecture. In summary: `lorax` must be ran in a native environment/archictecture. `xorriso` to repackage an ISO with packages can be done anywhere. Our [toolkit](https://git.resf.org/sig_core/toolkit/src/branch/devel/iso/empanadas/) is what helps us with this procedure. ---

Thanks… that’s what I thought, creating a bootable cd/dvd has to be native. I am going to have to jump through hoops. I have an old CentOS 6.8 installed on that p720. The GCC compiler on that system is going to be too old to build the new install. ---

If you’re willing to go through with trying to make it all work, you _might_ have better luck starting on Fedora 28. It’s still old yes since it’s closer to Rocky 8, but it’s better than CentOS 6 or 7. It may be worth a shot. See [here](https://dl03.fedoraproject.org/pub/archive/fedora-secondary/releases/28/). ---
