The file is:
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist
You need to add/edit two lines: the first is Kernel Flags and the second is mbasd=1.
Insert “mbasd=1″ in the <string></string> value below the <key>Kernel Flags</key> (If the string is not empty to begin with (it normally is), then use a space to separate the mbasd=1 from what’s already there). The file will then look like:
[Update: The file might not yet exist at all on some Macs. In that case, the pico editor window will initially be empty – if so, just copy and paste the entire XML block from below].
<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
<plist version=”1.0″>
<dict>
<key>Kernel Flags</key>
<string>mbasd=1</string>
</dict>
</plist>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
<plist version=”1.0″>
<dict>
<key>Kernel Flags</key>
<string>mbasd=1</string>
</dict>
</plist>
Then Reboot.
