Amiga 500 Won't boot from hard drive

[N3vpd]

Good day All, Six months ago my 500 was running normally. We moved and now it won't boot from the external hard drive (mtec)  Does anyone have any ideas. I have two hard drives and tried both , so its not the hard drive. I have not yet checked the battery on the rom board yet but please correct me if im wrong, it should still boot without the board in there. It does boot correctly from the floppy Drive. Thanks Much   Any Ideas??

Thanks for the reply,  I am under the impression that the standard 500 does not have a battery on the motherboard, just on the expantion board and yes it boots and runs a floppy normally. I have swapped out the ps and the hardrives.  Thanks

Ps  I have not switched out the controller

Thats what Im thinking. I use this maching For sstv and Enjoy it Much. There is not much in the controller though? I will let you know. Do you Play with emulation and can you emulat hardware as well Take care my friends
