Newbie to Forum - Glad I found it. :sayyes:
I have some different questions concerning Chassis Intrusion than what I have found in searching this site as well as others. I want to understand how it works and I really want to USE it.
The subject MBs are SuperMicro P3TSSA and P6SGA+ both with AMI BIOS, O/S is W2K Pro WS. SuperMicro offers a utility - Super Doctor III - that contains code to detect a Chassis Intrusion (CI) and also claims to be able to clear it. It provides for eMail or pager notification when a CI is detected. Sounds good - however, I have yet to figure out how it really works. On these boards the CI is a 2-pin jumper with 1 probably having a pullup to +Vsb and the other pin to ground. A CI is triggered by connecting (grounding) pins 1 and 2. When I do that, I do see a notification of a CI on the next boot.
This all implies there is some kind of API or a "reachable" place where the status of the CI latch can be read and manipulated. I would like to do exactly that. I have some specialized hardware that detects a true CI and turns on a solid state switch to crowbar some sensitive data and a second N/O solid state switch that I intend to connect to the CI input header pins.
When or if I detect a CI, I want to be able to display an informational message on the screen that a tamper has occurred and switch into a defensive posture. I'd would like to be able to programatically clear the condition, but do not care if we need to power down to recover since in order to recover the application two keys must be inserted in the power down condition.
So, that all being said, any an all help w.r.t. information, suggestions, code, times to meet for adult beverages for discussions etc. is greatly appreciated.
Thanks ... Abe .. Concord, NC
