It looks to me that the store_edid function is unconditionally calling the READ EDID function without first having called the installation check function. (Int 10h ax=4f15 bx=0) Ralf Brown's interrupt list (which is pretty much definitive afaik) also notes that for the READ EDID function, dx should be 0, we are using 1. Is there a reason for this ?
