How to disable watch dog after reboot on CentOS5

Hi, I have ASRock E3C226D2I chipsetC226.

I have enabled watch dog because I want to check hardware failure during the boot.
But after I booted OS, I want to disable watch dog.
How can I do this in CentOS 5.5 ?

Thank in advance.

5.5 is seriously not supported.
Current supported version is 5.11.
You should update immediately.

Hi, gerald_clark.

Thanks for the reply.

I understand.
You mean in no way I can't disable hardware watch dog on CentOS 5.5 ?

Can I disable harware watch dog in CentOS 5 latest kernel package?

Thanks in advance!

I doubt it very much. The hardware watchdog is a hardware feature but it requires a kernel module that communicates with it to let it know that the o/s is still alive and working. If you turn on the hardware watchdog and there is no kernel module loaded then the watchdog will kick in after its time limit and reboot the machine. How you would turn off the hardware watchdog from the running system is something you'd probably have to ask the hardware manufacturer.

Hi, TrevorH and list.

Thanks for your reply.

Yes, you're right.
It's not softdog but hardware watchdog.

So, I would ask Asrock, thanks.
