I stayed at a hotel in San Francisco and in their lobby were two iMacs for the guests to use, which I thought was definitely different but cool. The iMacs had an option on the screen for guest to choose whether they want to use Mac OS X or Windows XP. This startup option that I am referring to was not the regular hold down the option key and see the startup disks but more like a software or boot loader on the computer. Once you picked your platform of choice, the iMac would boot in that platform - literally boot and not a virtual boot in that platform. So, I knew the iMac was using Boot Camp but I did not know how or what software was used for the startup option.
My question to you is do you know of a setting in the Mac OS or a boot loader software that will allow this?
