Additional Screen

The isa option causes the system to display an additional text screen at the beginning of the installation process. Use this screen to configure the ISA devices on your computer.

Important

Other kernel boot options have no particular meaning for anaconda and do not affect the installation process. However, if you use these options to boot the installation system, anaconda will preserve them in the bootloader configuration.
