Boot loader: ?'s instead of .'s

Instead of getting the normal string of .'s from the boot loader, I am now
getting a string (never ending) of ?'s. What does this indicate?

BTW this is happening on a newly programmed M-Sys DOC, other DOC’s
programmed in the same fashion are working fine.

TIA

The ? marks indicate the image cannot be found. Are the disk translations
reported by fdisk the same as those which the BIOS reports?

Failure to read a block from the device.

Also not having an image will cause this. (i.e. the size of .boot is 0)
