BOS pre-release v1.11.0020 alpha

Restructured boot process to be more efficient, moved default binaries around a bit, made updates function more smoothly, improve attempt recovery option, and many bug fixes.

To update an existing BOS install, copy BOSUPDTR.BIN and BOSOSPT2.BIN to the root of a FAT32 formatted USB drive, run the msd program on the calc, select BOSUPDTR.BIN with enter and type in a name for the file, then select BOSOSPT2.BIN and type in that same file name. (this is important) Finally, press clear to exit the msd program, then run the updater program you just transferred.
Upon running the updater, the calc will reboot.
I am planning to add a dedicated updater program very soon to simplify this process.
