specify disk space for c drive in winnt

[foddo]

hi there

here i am again

i wanted to know if it is possible to do the following

say suppose i got 20 gb hardisk

i want to do unattended xp installation on it

so is it possible to specify in the winnt.sif file that i want the c drive to be 10gb ??? without having to create it manually?? if so what is the command

2) then i want a readymade script which will automatically format the remaing blank space in ntfs format and assign it the next drive letter

pls say so it is possible

thanks a lot

and keep up the good work

thanks
