>Unless I'm totaly confused (very likely!), the AMI Merlin DP is PCI based. it could be both PCI and EISA, ie PCI/EISA, whil Im suggesting it is desirable to get PCI/ISA. Im not trying to start a religious war here, just pointing out the differences. If you have NO EISA crds why put up with the limitations (primarily 4 less INT sources) of the EISA bus. If you do have EISA cards you want to re-use, and don't have an INT crunch, then EISA should work fine. Note that I have seen at least 1 PCI/ISA board that still requires "mixwd-mode" even though not an EISA board. And not all PCI/ISA boards take advantage of the upper APIC INTS (16-23). you really need to do your homework here. >Can someone explain why the P5 works by P6 does not? If we knew we could probably fix it!!! we have theories BUT we don't know for sure... search the mail list for "TLB shootdown" for the discussions.
