I have a sony vaio laptop model name is VPCCW26FG.
I wanted to install macintosh on it so I surfed internet for help.
First I was able to install hackintosh on my PC but on my laptop I wasn't able to... so I made a google-search and found out the problem was the AHCI mode which in my sony laptop bios there isn't enough configuration setting as in any other vaio laptops. (then I realized the system configures itself automatically depending on your need ,so I left this case).
I found out the problem was common but user's using this model and installing hackintosh are not many.
now the main thread which is essential for the experts reading this is I have 3 mac installation disk, One of them is IATKOS LS3 (MAC 10.6.3) and IATKOS LS1 (MAC LION) and One old disk using DARWIN (10.5.6) I Guess ;
The Old disk I can boot with command "-v -F busratio=18 arch=x86_64" and installation becomes successful but booting after install is not successful no matter what command I type.
The IATKOS LS2 is the same as my Old disk.
The IATKOS LS3 doesn't get the installation so I tried "-v" command it shows this message [pc configuration begins] and hangs. (I Used the npci=0x2000 command but not working ).
I'm sure there are many people having my problem but can't find anything so if I get this problem solved ,then I post a complete tutorial about this on my website with respect to experts answers in this forum.
