Looks like only change was the input cap, shouldn't make a difference.
The default BIOS settings work for me, I assume your SoM has the same BIOS as me.
There looks to be a slightly concerning blob of solder between C6 and C31?
Also perhaps clean flux from around crystal, sometimes they can be finicky.
I guess double check your SoM soldering on the ISA lines as you say.
EDIT : oh and actually, you said your voltage was like 4.7 - try getting it closer to 5v. Use a different supply or cable. Possibly the crystal chip doesn't like the lower voltage.
