What is Installation disk?
The Remote Installation Boot disk allows the RIS server to be used by clients that do not have a PXE-enabled network adapter. The boot disk creates a PXE emulator that works on supported PCI network adapters that allow them to connect to the RIS server. Since one disk works for all network adapters, a specific network boot disk is no longer required. The supported network adapters are listed in the utility that creates the boot disk. This utility is named Rbfg.exe and can be found in the network folder:
reminst\admin\i386
RBFG floppy disks only support the adapters that are listed in the adapters list box. All of the adapters in this list are PCI based adapters. Network adapters that are ISA, ISA(pnp) and PCMCIA based are not supported. This disk can be useful when you need to use RIS to install programs to a laptop. Because we do not support PCMCIA, you can place the system in a docking station and use a RBFG generated boot disk to connect to the server provided the docking station contains a supported PCI network adapter.

What is a bootable CD?
LiveDistro is a generic term for an operating system distribution that is executed upon boot, without installation on a hard drive. Typically, it is stored on bootable media such as a CD-ROM (Live CD), DVD (Live DVD), USB flash drive (Live USB), among others.
The term "live" derives from the fact that it does not reside on a hard drive. Rather, it is "brought to life" upon boot without having to be physically installed onto a hard drive.
A LiveDistro does not alter the current operating system or files unless the user specifically requests it. The system returns to its previous state when the LiveDistro is ejected and the computer is rebooted. It does this by placing the files that typically would be stored on a hard drive into temporary memory, such as a ram disk. In fact, a hard drive is not needed at all. However, this does cut down on the RAM available to applications, reducing performance somewhat. At least 256 MB of RAM is recommended, but some LiveDistros do fine with less.
