I had no specific problem in mind, just speculating as to why it might be better to use the WDT. And you answered my question, that the WDT reset is more complete. But in fact, I put a scope on it, the Hardware Reset Initiated by Software also activates RESET# on PCI bus (~10-15ms, A15), so it appears that both PCIRST# and CPURST# are activated. -Steve _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
