Hey guys. Do I recently purchased an old asus a8n sli deluxe motherboard to replace the emachines motherboard that runs the computer in that is in charge of running my cnc mill. In order to run the software (centroid v2.70 / cnc linux in case it’s important) I have to boot the computer for a cd and install the software onto a compact flash which is serving as the hard drive. Now im fairly new to computers, but I’ve been very diligently researching any Possible solution for the cd not being picked up by the computer. I’ve switched jumpers and ide cables in every possible configuration imaginable and every time it tries to boot, it reads “missing operating system”. I’ve dumped more money into this machine than I care to mention, and it’s at the point that I’m considering selling the centroid controller and getting something like gecko servo drives w/ pmdx B.O.B. And running Mach 4 instead But before I do I wanted to try one last Hail Mary attempt and see if somebody out there has the answer to this problem. Just so it’s clear, this operation has to be done on a computer with ide “ribbon” cables and original pci slots so I can’t do it on a newer computer, I’ve tried, there no current os on the computer, tho I do have a card drive with wIndows xp installed that I can use if that is a factor for some reason, all the components connected to this motherboard are salvaged from different computers so idk if there is a compatibility issue (cdrom drive is lite-on it corp) and the flash card is connected via ide-compact flash adapter. As mentioned I’ve tried both cf card and cd drive as master and slave, and both on the same ide cable and on separate cables so I don’t believe it to be an issue with the drive configuration. Any help would be greatly appreciated. Thank you in advance
