[Tfug] grub question

[Matthew Eskes]

Actually, thats not quite the right thinking...
The GRUB config file is parsed like any other confile file in Linux, meaning 
that if there is is a hash mark there, it is ignored. For those options to 
take effect, you still need to uncomment them. This leads me to somewhat of 
any odd question, if you have a half gig of RAM, why are you wanting to use 
only a quarter gig? Anyway, even if it is in "automagic", if you need to 
make a change, you still need to uncomment them, iirc.
