sorry, I was forgot to add MD5 file
here.. download following MD5 file and put onto same folder with your downloaded files.
http://rapidshare.com/files/137716534/JaS.OSx86.10.5.4-z0r.md5
Install
QuickSFV for Windows or
MD5 for Macopen (double click) "JaS.OSx86.10.5.4-z0r
.md5" file, it will verify all of your downloaded files.
if there is any error/mismatch on one or more MD5 checksum,
then you have to re-download that file(s) only until all MD5 checksum are OK
