Hi, |

|

I recently bought a MSI GM-IM45 [1] mainboard which includes a (hardware) |
4 |
watchdog timer. Now the problem is that I don't know how to prevent it from |
5 |
resetting the system. There seem to be two possible ways but I'm unable to |
6 |
make either one of them work... |
7 |
|
8 |
1. There is a BIOS setting to enable/disable the watchdog: When I set it to a |
9 |
specific time it resets after the set interval, but when I disable the watchdog |
10 |
the reset still occurs (I don't know the exact interval yet and I'm unsure if |
11 |
it stays the same). So no luck here. |
12 |
|
13 |
2. Feed the dog: I don't know what kind of watchdog it is so I don't know |
14 |
which driver I should use. I tried a live CD where I modprobed each of the |
15 |
watchdog driver modules (one at a time) and then wanted to prevent it from |
16 |
resetting with a looped "echo 1 > /dev/watchdog" with no success. |
17 |
|
18 |
There is some information on the watchdog timer in the user manual [2] on page |
19 |
64 f. including some assembler code. But I'm not able to get something useful |
20 |
out of it. |
21 |
|
22 |
Any clue on this would be very appreciated, especially: |
23 |
- Why the BIOS setting won't work as expected |
24 |
- How to find out which watchdog chip it is |
25 |
- If the "echo 1" should work when I've found the right driver |
26 |
|
