checking hda during while boot by knoppix BOX

[bing yu <byu@mail.sim.ac.cn>]

hi all
 
There is a message while I booting my knoppix Box 

---message begin----
checking rootfile system fsck1.35 wip..
/dev/hda8/ has been mounted 33 times without being checked, chech force 
[===                                   ]20%..
---message end----

I would like to have the knoppix Box check root file system less
frequently, say check once every another 100 booting. 

where can I get this job done? modify which config file?


Thank you for your attention!
