Problems installing fedora release "yarrow"

[Sarath Chandra Janga]

Hello 
   When i try to install fedora release yarrow on dell latitude  d800 a
pentium m 1.7 ghz machine, 512 mb ram the installation stops after it
formats the  root partition showing a message that the error could
possibly because of insufficient disk space while hard disk is 60 gb and
installation partition is about 4 gb and the total size of the to be
installed is just about 2.5 gb though i tried to do several other
combinations.when i try to install the same amount of software with red
hat 9.0 i see that it installs very easily without any problem.Is this a
bug or can this solved by giving some commands to the boot prompt when
installing.I tried to install in text mode and also nofb too just to
check.. but in vain.
Any kind of help would be greatly appreciated.
