Well Actually our PC Hardware doesnt support Mac Os X Tiger. Go to download.com and download everest ultimate software and run it, see your PC config then if it supports SSE2 or SSE3 then you can proceed with this tutorial (SSE3 is best!) or else MAc will not work on mmx or any other processor instruction set "you got have sse2 or sse3 support".
So you have SSE3 support for your microprocessor, goto www.torrentspy.com or any other torrent and download Mac Os X Tiger X86 jas.torrent. Now Rip this on to a DVD, you got to have a lots of hard disk space like 60GB OR 120GB, 120GB is recommended, So now you have the Mac Os X tiger x86 DVD and you have windows xp running on your computer. Now except your c: (i.e where windows xp is installed) delete other partitions using disk manager in win xp admin tools, and then create two fat 32 partition of any size but one partition should have large size this is where MAC is going to be installed, ok then reboot the system, insert the dvd and set CD/DVD as your first boot option in your CMOS settings, DArwin Boot LOader gets loaded from the DVD, press enter , you will get a white screen and a greay APPLE logo then after few min, you will get a option to format your harddisk partition so select as mac os x and then click next and then it will copy all the files and MAC OS X gets installed on your PC ........WOW now you have both windows xp and also MAC OS X .....SO enjoy guys and have fun and explore technology . if you have any questions or comments just put it in the CBOX.
