Some spell-check issue.

[jsjasonseba]

It seems like the spell-check detects 'KiB' as an invalid term, even tough it should be valid. I have removed it.

[potiuk]

There is a list of allowed words. KiB is not on it. you can add it there, or you can KiB quote the word to avoid spellchecking it.

[jsjasonseba]

I wasn't aware of the list of allowed words. Let me add it to the list. Thanks for letting me know.
