is there a Eprom on the NAS 220? if so where in the unit is it located? Is there a file that can be written directly to the Eprom? Thanks in advance.

The short answer is yes, it does, but it’s not user accessible or serviceable.

The question though is why, what do you need to do that can’t be done via the GUI, and if it’s not booting at all, given it’s age, it’s likely time to move on.

It’s 16 years old.

If you want to boot it to get data off the disks, they’re mirrored disks, so mounting one in another machine should allow you to access the data.
