[ipxe-devel] BootServices watchdog timer disable

[Bradley B Williams]

The UEFI spec calls out that the Boot Services will start a 5 minute 
reset watchdog timer. On the Dell M620 I am using this causes the ^B 
breakout to iPXE shell to only be available for about 5 minutes. I have 
not studied the iPXE tree enough to know the proper placement of this 
code in the "shell", but if this call could be added to the shell's 
init() it would help extend my debug time. The code would use the 
BootServices table to call like: bs->SetWatchdogTimer(0,0,0,0);

Thanks.
