This installs the BT4 by default cannot save the configuration, each time you change the setting, the next reboot does not have. Download a compressed package called "Savefile.rar" on the internet, size 40K or so, this is BT4 can save the configuration key, of course, there are other ways, but this is the simplest. Decompression that compressed package, there is a corresponding size, choose a suitable size, used as a BT4 to save the configuration of space, I am a 8G u disk, selected a 2G, and then unzip. Note here, many places on the web said that as long as the first decompression out of the file, choose a suitable size, renamed "CASPER-RW", copy to the root directory of the U disk can be, in fact, is misleading, should be extracted after the suffix ". bz2" of the compressed package and then extract the extracted files (no suffix name) , renamed "CASPER-RW" and copied to the root directory of the USB stick. At this time under the Windows system you look at the properties, you can see the size of the file, you unzip how big, see is how big. Then open the Syslinux.cfg file under the root of the USB stick (can be opened with Notepad), the Boot=casper nopersistent rw quiet vga=0x317 modified to: Boot=casper persistent RW quiet vga=0x317 only removed a no, save the exit, at this time the BT4 has been able to save the configuration. Here is still to note: you will see multiple boot=casper nopersistent rw quiet vga=0x317, because it has multiple startup options, choose the default boot to know the first one is good, if you can not rest assured that the whole change, Such a portable BT4 with a saved configuration was made.
