Prepare Clover booting USB

• installing clover to usb As Rehabman's recommendation in the laptop installation guide, I used the option 1: FAT32 + HFS+J partitions, convenient for mounting the EFI folder.

  The completed Majove booting USB is:

  > diskutil list
  ...
/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *15.5 GB    disk2
   1:                 DOS_FAT_32 CLOVER EFI              209.7 MB   disk2s1
   2:                  Apple_HFS Install macOS Mojave    15.3 GB    disk2s2

    This the most import kext for lenovo E42-80, if no this kext, the laptop can't boot into the macOS installer, will froze at the loading bar comes out(boot with args -v). credit @hswwm, refer this post at the chinese language forum.

    Issue description: when trying to install majove on E42-80, mostly the system can't boot into the installing phase. That was when you finished the installation pahse 1, system will frozen when the loading bar comes out after rebooting. Even reboot, it will still froze at the loading screen. I've tried several ways to fix the problem, including injecting the fake graphic id, changing the boot args with -f(hopes clear the cache). Sometimes, when I changed the config file, maybe can finished the installing phase 1, but frozed again after reboot. The issue finally fixed by add this kext: VoodooTSCSync.kext.
