BIOS Setup Interface Intel® Server Board S1200V3RP TPS
Revision 1.2
8. FRB-2 Enable
Option Values: Enabled
Disabled
Help Text:
Fault Resilient Boot (FRB).
BIOS programs the BMC watchdog timer for approximately 6 minutes. If BIOS does not
complete POST before the timer expires, the BMC will reset the system.
Comments: This option controls whether the system will be reset if the BMC
Watchdog Timer detects what appears to be a hang during POST. When the BMC
Watchdog Timer is purposed as an FRB 2 timer, it is initially set to allow 6 minutes for
POST to complete.
However, the FRB 2 Timer is suspended during times when some lengthy operations
are in progress, like executing Option ROMS, during Setup, and when BIOS is waiting
for a password or for input to the F6 BBS Boot Menu. The FRB 2 Timer is also
suspended whi
le POST is paused with the
<Pause> key.

9. OS Boot Watchdog Timer
Option Values: Enabled
Disabled
Help Text:
BIOS programs the watchdog timer with the timeout value selected. If the OS does not
complete booting before the timer expires, the BMC will reset the system and an error
will be logged.
Requires OS support or Intel Management Software Support.
Comments: This option controls whether the system will set the BMC
Watchdog to detect an apparent hang during OS boot. BIOS sets the timer before
starting the OS bootstrap load procedure. If the OS Load Watchdog Timer times out,
then presumably the OS failed to boot properly.
If the OS does boot up successfully, it must be aware of the OS Load Watchdog Timer
and immediately turn it off before it expires. The OS may turn off the timer, or more often
the timer may be repurposed as an OS Watchdog Timer to protect against runtime OS
hangs.
Unless the OS does have timer-aware software to support the OS Load Watchdog Timer,
the system will be unable to boot successfully with the OS Load Watchdog Timer
