oracleVM, it's not bad very small actually. the program folder,only 1.44mb now anything you want to install to the VM will be on the harddrive.
if you have the 106G of free space and at least 2g of ram you probably wont notice any slowdown at all having both running.
in short you need to be able to dedicate as much ram to the virtual system as you would to a real system.
on the dell i just built from junk, having only 1G real ram i do notice a slowdown but no errors.. after the virtual ramdrive mod, It runs much smoother but still "just noticeable"
while with this laptop having 3G of real ram installed it zings,has no visible slowdown.
I just run the benchmark test and it performs on the laptop in vm better than it does on the real computer i just built..
you might also like the calmera, which is a 3.1 upgrade having the original 3.1OS but with video and hi res graphics ability. "almost 98 my thinking on it is it is so obsolete/unpopular, maybe hackers and attackers wont have documentation/tools on 3.1 to do anything to it.. hows that for online security?
