(Damn Vulnerable Windows XP: Lesson 7)

{ How to Increase the VMWare Boot Screen Delay }


Section 0. Background Information
  1. Why slow down the VMWare Boot Screen Delay?
    • Sometimes a person might want to use a bootable CD or USB flash drive, that contains an ISO file, to clear a password with Hiren's or remove a Virus with Kaspersky.
    • Unfortunately, you have to have Jedi Ninja reflexes to Left Click and press the <Esc> button once you see the VMWare Boot Screen to access the Boot Menu.
    • Fortunately, the VMWare virtual machine configuration file (.vmx) allows you to delay the boot process by using the bios.bootdelay configuration parameter. E.g., bios.bootdelay = "20000".

  2. Pre-Requisite
  3. Post-Requisite
  4. Lab Notes
    • In this lab we will do the following:
      1. Discover the Path of the VMWare virtual machine configuration file (.vmx)
      2. Configure the bios.bootdelay configuration parameter to delay the VMWare Boot Screen by 20000 milliseconds (ie., 20 seconds).
