Hello all,
I am designing a PCI card who must be able to reset the computer.
I mean that the card must reboot the computer the same way that if an
user
pushed the RESET button of the computer case.
Does any one know if there is a way to reset the computer from a signal
on
the PCI bus ?
I know there is a RST pins but, I believe this pin is to inform the
expansion board when the computer reboot.
I want to do the inverse, I mean, that the expansion board instruct the
motherboard to reboot.
Any help will be greeeeeeaattlly appreciated. This point is very very
important for me...

The PCI Watchdog adapter is your systems and peripheral applications protector! PCI Watchdog adapter provides user selectable refresh timer to be used inside your PC, which prevents the computer to hang by automatically resetting the system of your computer. When the PCI Watchdog adapter is enable, the system software or application program must refresh watch dog before selected time slice is reached, otherwise the computer will be reset, and the power of power control box that connects to peripheral devices will also be reset. The PCI Watchdog adapter is a 32 bits PCI bus board with Plug and Play (PnP) features; it is a programmable I/O interface card for Pentium, or compatibles. The PnP features let hardware configuration for IRQ and I/O address is detected by BIOS automatically, you don't need set switch and jumper. In the distribution diskette, we provide software for Windows 98, Windows NT4.0 workstation, and Windows 2000 operating systems.

Application
On industrial application, lots of computers are automatically operating itself once the power turns on. In case the application got hang surely the computer and its operation hang also. If you don't boot your computer again it will not go back to its regular operation, but not with the watchdog! Because once the watchdog was not refreshing, it will reset the computer automatically! While using your computer, unexpectedly your modem got hang. One way of connecting it again is to switch off then turn on your modem to continue on working. But now, it's the new way around, PCI Watchdog will be automatically reset the modem power. It will protect your application software system.

The Difference between Watchdog I and II

The advantage of Watchdog II over the Watchdog I is that the Watchdog II has an expansion power control box that can control external component. When reset signal activate of the Watchdog II, it will also reset the power of power control box.
