Inserting the CD and booting
After downloading the Elastix Unified Communications Server software, the file will be saved as an ISO image. It is mandatory to "burn" this image to a CD by using burning software and selecting the BURN ISO IMAGE or BURN ISO or BURN IMAGE option.
How to do it…
- Turn on the destination device (PC or Server).
- Place the CD into the CD tray immediately after turning on the PC/server. If all goes well, we will see the following screen:
- Press the Enter key at the boot prompt to start the installation process.
There is more…
We can wait for 15 seconds or simply press the Enter key, and the installation process will start automatically. However, we will describe the options accessible with the F1, F4, F3, F4, and F5 keys. The first option F1-Main will allow us to return to the Main Booting Menu. The F2-Options are the Installer Boot Options.
In this option, it is possible to select booting options such as to disable hardware probing (linux noprobe), enable rescue mode (linux rescue) and so on. To enable any of these booting options, we just type the desired option after the boot prompt and press Enter. Sometimes, when the Advanced Programmable Interrupt Controller (APIC) is present on newer motherboards and causes some problems during installation, it has been known to cause problems on older hardware. In order to avoid such issues, it is better to disable it. This can be done by typing linux noapic or linux acpi=off. This is useful on some older systems and is a requirement for using advanced power management (APM). This will disable the hyper-threading support of our processor. The F3-General option will display the General Boot Help.
The F4-Kernel provides Kernel Parameter Help. To pass an option to the kernel, we use the format: linux <options>.
The F5-Rescue option is used for rescuing an already-installed system.
