It's worth noting that this site, TonyMacx86, isn't well-liked by some of the Hackintosh community, because they plagiarise and rebrand software and drivers helpful or necessary in Hackintosh setup. The guide may be useful, but please get your setup tools from the original sources.
My main source for this is conversations I've had in IRC, but it's also been noted elsewhere.[0][1][2][3][4][5][6][7][8]
Also, apparently they have weird anti-piracy measures on their software... software which they stole from others![9]
If you want Hackintosh install software which isn't stolen, I suggest myHack: http://myhack.sojugarden.com/ (I'm unaffiliated with it, but I've used it and I've had it recommended to me.) Unfortunately, myHack is now proprietary, because the author has had their code stolen in the past. It is, however, freeware.
