The boot loader ignores input parity and strips the 8th bit. Only 7 and 8 bits are supported. If no key is pressed for the specified time, the default image is automatically booted. Similarly, password input is aborted if the user is idle for too long. The default timeout is infinite.
Higher numbers give more verbose output.
The maximum verbosity level is 5. They are used as defaults if they aren't specified in the configuration sections of the respective kernel images. This chain loader does not pass partition information in the boot sector it loads. This specifies the device that contains the partition table. The boot loader will pass default partition information to the booted operating system if this variable is omitted.
