Alt+F1 Boot Menu
When you run ArcaOS or OS/2 Warp 4.5 you can press "Alt+F1" at startup (When the OS/2 little box shows) to access an special menu to help you with some troubleshooting.
F2
The F2 option will allow you to boot OS/2, but it will send you to the command line.
Some important notes:
- This boot procedure uses "?:\os2\boot\config.x" for config.sys.
- You can execute "SET | more" or "ENV | more" to view the enviromental variables that are stored.
