-- UnBIOS by JackMacWindows
-- This will undo most of the changes/additions made in the BIOS, but some things may remain wrapped if `debug` is unavailable
-- To use, just place a `bios.lua` in the root of the drive, and run this program
-- Here's a list of things that are irreversibly changed:
-- * both `bit` and `bit32` are kept for compatibility
-- * string metatable blocking (on old versions of CC)
-- In addition, if `debug` is not available these things are also irreversibly changed:
-- * old Lua 5.1 `load` function (for loading from a function)
-- * `loadstring` prefixing (before CC:T 1.96.0)
-- * `http.request`
-- * `os.shutdown` and `os.reboot`
-- * `peripheral`
-- * `turtle.equip[Left|Right]`

-- Set up TLCO
-- This functions by crashing `rednet.run` by removing `os.pullEventRaw`. Normally
-- this would cause `parallel` to throw an error, but we replace `error` with an
-- empty placeholder to let it continue and return without throwing. This results
-- in the `pcall` returning successfully, preventing the error-displaying code
-- from running - essentially making it so that `os.shutdown` is called immediately
-- after the new BIOS exits.
--
-- From there, the setup code is placed in `term.native` since it's the first
-- thing called after `parallel` exits. This loads the new BIOS and prepares it
-- for execution. Finally, it overwrites `os.shutdown` with the new function to
-- allow it to be the last function called in the original BIOS, and returns.
-- From there execution continues, calling the `term.redirect` dummy, skipping
-- over the error-handling code (since `pcall` returned ok), and calling
-- `os.shutdown()`. The real `os.shutdown` is re-added, and the new BIOS is tail
-- called, which effectively makes it run as the main chunk.
