Hi Guys,
IBM has introduced a new fixlet named “Force network boot”. Can anyone please shed some light on how it works.
When I try to use it. It reboots the machine with the same boot sequence and doesn’t force the machine to network boot.

Hi
The fixlet does not alter the boot sequence.
What it does really varies depending if the machine is BIOS or UEFI.
For BIOS it replaces the system MBR with a property one. This MBR once booted (at next reboot time) causes Interrupt 0x18 pretending that BIOS was unable to identify any bootable disk volumes. Hence if in your boot sequence contains a network boot it is attempted.
For UEFI it searches existing PXE boot options and if found it use it to define a boot next option, so at the next boot this device is booted first.
To dig further you need to look at the log file of the command invoked in the fixle and that is responsible of the above mentioned process. It should be under:
C:\Program Files\BigFix Enterprise\BES Client__BESData\actionsite__Download
and it is named rbagent.log
