Thanks for advice.

Appears SATA-cable is not the problem. I switched SATA cables between Cd-rom and Harddisk, and it didnt help, neither did it help to switch their power cables.

Hence I guess my only option is to do as LiveForit suggested, to get AOS4 on a Cd to get it to boot.

Was about to boot my SAM460EP after a while, and this is the message I faced:

"no SLB found in any of the designated boot sources: returning to u-boot"

I am suspecting the problem would be with HDD, but if I understand the boot text correctly, it seems like it does recognize the HDD, I think when booting it said SATA: found, which I suppose means the HDD.

Anything I can do here? To either get it to work, or to confirm problem is HDD?

I dont have AOS4 on disc or anything, I only have it on this HDD, as I bought this used, so if problem is failed HDD, then not much I can do.

For last years I havent done much inside machines, so I am not sure what I see there anymore.

I opened the machine and checked the one I assume is HDD, unplugged two cords: SATA-cable and powercable I suppose, and replugged them in, in hopes it had been a connection error, but no use.

Any advice what to do?
