+**Annotation Encoding**
+  
+Refined from last post, two 32-bit annotation words per binary image word,  
+

+================================  
+00EEEEEEDDDDDDCCCCCCBBBBBBAAAAAA - LABEL : 5 6-bit chr string ABCDE  
+  
+FEDCBA9876543210FEDCBA9876543210  
+================================  
+..............................00 - DAT : hex data  
+AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA01 - GET : get word from address A\*4  
+AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA02 - ABS : absolute address to A\*4  
+AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA03 - REL : relative address to A\*4  
+  
+Going to switch to just 2 lines per word displayed in the editor,
+Only DAT annotations show hex value, other types show LABEL of referenced address
+in the place of the hex value. So no need for an extra note.
+In practice will be using some amount of binary image memory to build up
+a dictionary of DAT words representing all the common somewhat forth like opcodes,
+then GET words in the editor to build up source.  
+  
+Need to redo the bootloader from floppy to harddrive usage,
+and switch even the bootloader's 16-bit x86 code to 32-bit aligned
+LABEL'ed stuff so the final editor can edit the bootloader.
+Prior was avoiding manually assembling the 16-bit x86 code in the boot loader,
+but might as well ditch NASM and use something else to bootstrap everything.
