Comments

If a validated OS is not detected, this routine will wait to receive one instead of resetting RAM.

These routines only exist on the TI-84 Plus, not on the 83 Plus.

The table of strings is at 7F:5EF7h on 84+SE boot code 1.02, but the most useful offsets are below:

"Receiving...": 0000h
"ERROR!": 001Eh
"Validation Error": 005Dh
