There has been a new free tool for customizing ISO images. The latest version is 2.7. This tool is unsupported by VMware, but can be used in your home lab for integrating unsupported LAN drives for example. The tool creator is a German VMware user – Andreas Peetz, which created this tool for his own use at first but you can support him by donating, since he made this tool widely available.
It's actually a script which brings a GUI window, where you can specify:
1. The source VMware ISO image
2. The driver package you want to integrate
3. The destination folder of the final ISO
You can download the latest version here.
A quick quote from his website:
ESXi-Customizer is a user-friendly script that automates the process of customizing the ESXi install-ISO with drivers that are not originally included. Unlike other scripts and manuals that are available for this purpose ESXi-Customizer runs entirely on Windows and does not require any knowledge of or access to Linux.
Just for your information, a modification of ISO images and running production hosts on images built from such a modified ISOs it's not supported by VMware.
In the latest release of ESXi Customizer 2.6 – what's new?
– With this version you are able to optionally create an (U)EFI-bootable ISO file for the installation of ESXi 5.0. (U)EFI stands for (Universal) Extensible Firmware Interface. (The original VMware ESXi ISO does support (U)EFI already, so If you want to keep this functionality in the rebuild ISOs, you might want to check that box.
– Additional script is included called Tgz2Vib5 – this convert an OEM.tgz-style driver package into a VIB file (for ESXi only).
