Novell ZENWORKS 10 CONFIGURATION MANAGEMENT SP3 - PREBOOT SERVICES AND IMAGING REFERENCE 10.3 16-04-2010 User Manual page 18

NBPs are analogous to the bootstrap programs found in the Master Boot Records (MBRs) of other
boot media, such as hard drives, floppy disks, CDs, and DVDs. The purpose of a bootstrap program
is to find and load a bootable operating system. MBRs on traditional boot media accomplish this by
locating the necessary data on their respective media. NBPs accomplish this by using files found on
network servers, usually TFTP servers.
ZENworks Preboot Services uses two separate NBPs working together:
"nvlnbp.sys" on page 18
"pxelinux.0" on page 18
nvlnbp.sys
This NBP has the following responsibilities:
Detect various SMBIOS parameters and local hardware
Read the ZENworks identity information from the hard drives
Communicate with novell-zmgprebootpolicy to determine if there is any preboot work
applicable to the device
Present and manage the Novell Preboot Services Menu
If necessary, launch
pxelinux.0
The primary purpose of this NBP is to load the operating system that is required to execute the
assigned preboot work.
