I have a 8 GB flash drive and a 4.3 GB DVD iso (openSUSE-11.3) Is it possible to use the flash drive to install the linux? Pendrive linux universal USB installer formats it to Fat32 which limits the filesystem to 4 GB.

Consider downloading openSUSE 11.4; see this openSUSE Wiki portal page. – bwDraco Jun 8 '11 at 22:24

Yes. UNetbootin is a tool that will extract the ISO onto a thumbdrive so that you can boot from it. It should work like a DVD would, allowing you to install from the thumbdrive.

How does this circumvent the Fat32 4GB limitation? – Jader Dias Jun 8 '11 at 23:15
The utility writes the contents of the ISO image directly to the flash drive as a partition. The ISO image itself is not written to another filesystem. – bwDraco Jun 9 '11 at 0:31
