The reason behind this idea is establishing a single lab would be cost the institution so much. So, we modified the server and hope we could reduce the cost and easy to use for single server into different purpose labs in a single lab using a diskless server and will be also the diskless client. Also, here, in Indonesia, as a developing country, we have so many problems, including hardware cost and maintenance, electricity, many not well-educated and not well-informed operating computer. Those problems also cost so much for the institution. To achive this, we made a custom-made OS for server to be able to booting from storage devices and then transfer the whole system into RAM, including PXEBoot and NFSRoot services and specific contents for the labs in that time, ex: labs for CBT, eLearning, and so on. So, the server become diskless server and the client could booting in diskless client.
