I would go to the red hat web site and grab the RHEL 6.2
the old 5 will not even install on some new laptops
have your company pay the $299/year support license
it is mandatory !!! but your office might have a group license - check
Also be warned
a vm can not see your wireless it sees wired connections
Also RHEL 6 was never designed for laptops ,so not everything might work right
the common laptop problems are ,no sound and ,no mouse .
