These BCALLs display a certain error message along with "Press any key to turn unit off. Then turn unit on.", then wait for a key and reset RAM. TI also uses these bcalls as placeholders for future real bcalls.
- DE: offset into table for string to display
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 "Validating...": 006Eh "Version Error": 00B0h
