Shorten the sentence to reduce repetition, as the correlation with the boot chapter
is already explained in the previous sentence.
Add 'function' to `protected_mode_jump`
s/We already know from the earliest parts that entry to protected mode is located
in the `boot_params.hdr.code32_start` and you can see that we pass the entry of
the protected mode and `boot_params` to the `protected_mode_jump`
/The entry to protected mode is located in the `boot_params.hdr.code32_start`
and passed together with the `boot_params` to the `protected_mode_jump` function/
Correct grammatical errors:
s/in the end of the/at the end of/
Improve word choices:
s/gets these two parameters in the/receives these two parameters within the/
Add missing punctuation and add filling words for a more fluent reading.
