Thanks allot for those who answered to the unfinished post before, (I thought it would be possible to edit them later).
Bob_Zimmerman: "Check Point's "appliances" are really just x86 servers with weird PCIe slots and no video. You should be able to boot them from a USB drive, though you will be limited to OSs which can work over a serial console. You might be able to use GUI-based OSs with the LOM's KVMS functionality, but it's pretty flakey in my experience.
To reinstall Check Point's software on them, you will need three things: an ISO image for the version you want to use, a USB drive, and a tool called ISOmorphic to set up the USB drive from the image. Once you have imaged the drive, be careful with what you plug it into. There is an option in ISOmorphic to set the drive to automatically overwrite the OS on a system which boots from the drive."
- Yes I saw. The plan before was, to use one as a Gaming Server and the other for "open projects" because both have a ridiculous amount of Ram, may the Public services ministry became a custom version...? In the meantime, I plug in the other SAS from the working system, and it could boot up. So I think it could be work when I just mirror the working SAS to the new one? Otherwise, I will follow your recommendation.
