I does find the disk. My first step was to remove the old disk and install a fresh system until ready to boot. It did and i removed the new disk to re-attach the old one. Then no boot anymore. The old disk on the same port in place of the new disk did not boot. I think that's because the bios does use some ID flags to identify the disk to boot of. I never noticed that kind of behavior on legacy systems. Regards Kai --- GoldED+/LNX 1.1.4.7 * Origin: Monobox (2:240/77) .
