That's fully supported, if you want to do it, and is even the default if the drive is already MBR partitioned. The difference between the two is that GPT is a lot more flexible than MBR (no 4-partition limit, for instance), and allows nice things like labels. There's no old/new machine difference -- 386s can boot GPT just as well as Core i7s. But it's really a matter of personal preference. The only real difference is that you can't dual-boot Windows with a GPT disk (this is why only the "Entire Disk for FreeBSD" option in the installer sets up GPT). We can extend the online help to this effect. -Nathan
