Unattended Installation from USB | VMware ESXi 4.1 Update 1 | Instalación desatendida desde USB

If you are looking for an unattended installation of VMware ESXi 4.1 I strongly suggest you to visit Ivo Bereens blog and follow his post Create a bootable VMware ESXi 5 USB stick in Windows and perform a scripted installation,, this works perfectly fine, also you can use Lili Linux Live USB Creator and make your life easier as this tool do all the work for you, this is tested for ESXi 4.1 update 1, you can get a copy from here. There's also a post regarding ESXi 5 that uses Lili Linux Live USB Creator, also don't forget about PLOP, this tool will help in the testing process as it allows VMware Workstation to boot from USB, Ivo has a post about this (this guy rules, isn't he?).
