create usb install for esx / esxi

First format your usb / flash drive with FAT. Then copy all the contents of the installer .iso onto the drive.

Next delete isolinux.bin and rename isolinux.cfg to syslinux.cfg

Edit syslinux.cfg and append “usb” to the line starting with “append” … i.e. similar to this

append vmkboot.gz — vmkernel.gz — sys.vgz — cim.vgz — ienviron.tgz — image.tgz — install.tgz usb

Next grab the latest syslinux.exe (zip for windows) from here and run syslinux -s –ma <driveletter>:

Done.
