With VMWare Workstation Easy Install you can install an OS without any input. How does it do this? Is the support for this built into the OS, or does vmware do some magic to automatically select the correct options?
The support is built into the OS. For example, in the case of Windows guests, VMware generates a floppy disk image containing a txtsetup.oem
and some other files used for Windows' unattended-installation feature.
