I’d like to ask everyone two questions:
1. What tool can be used to modify the IO.SYS file?
2. In 2.CONFIG.SYS, different boot options can be configured separately. Can AUTOEXEC.BAT do that too? Or to put it another way, since CONFIG.SYS is loaded before AUTOEXEC.BAT during startup, is it possible to carry out different configurations in CONFIG.SYS according to the menu choice made in AUTOEXEC.BAT? If so, how can it be done?
