Dropping DMAR table - how to enter OEMTableId value such as EDK3?

Just starting to install Sonoma 14.5, maybe things off to slow start. I get error about no schema for OEMTableId context delete. So it is referring to my config.plist entry where I specify dropping the table. At first I had 8 zeros. Not that I am getting this error, I took a look at my edited dmar table and see its OEMTableId as

"EDK3 ".

So the 4 characters followed by spaces. I see that this in hex without spaces is 45444B33

Is that what I enter or are the bytes reversed?

thanks
