I have a 13" MacBook Pro Unibody with 2gb of ram in it. I am waiting on my 4gb to come in the mail and I am going to replace it tomorrow. Currently I am dual booting into Windows 7 with VMWare and it only has 512mb allocated to it. Is there anyway I can reallocate a different amount of RAM to Win 7 without doing a full reformat? If anyone could please let me know as soon as possible I would greatly appreciate it!
