From 7f4da4745c34287938ce76b92b23409adeecb5b8 Mon Sep 17 00:00:00 2001 From: Thomas Mingarelli Date: Tue, 4 Dec 2007 17:41:54 +0000 Subject: [WATCHDOG] HP ProLiant WatchDog driver Hp is providing a Hardware WatchDog Timer driver that will only work with the specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer will generate a Non-maskable Interrupt (NMI) 9 seconds before physically resetting the server, by removing power, so that the event can be logged to the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory (NVRAM). The logging of the event is performed using the HP ProLiant ROM via an Industry Standard access known as a BIOS Service Directory Entry.
