I'll copy them here: Answer 1: PCI is faster then VLB, VBL is faster then EISA, EISA is faster then ISA This is just a simple way to look at it and alot depends on the type of cards used(ie bus mastering). ISA slots take only ISA 8/16 bit cards EISA slots take EISA and ISA PCI slots take PCI and I don't know if you can use them for anthing else I have and EISA/ISA machine and a PCI/ISA machine I dont know how well the PCI and EISA chips get along. Answer 2: An EISA board will not fit into an ISA slot. An ISA board will both fit into and work in and EISA slot. The PCI/EISA and PCI/ISA combination slots have separate and independent connectors for PCI and (E)ISA cards which share nothing but the physical space in the computer. Since the two buses are independent, there should be no PCI performance penalty in using a PCI board in either configuration, all else being equal.

Intel has been having NUMEROUS problems with their PCI architecture, and the Local Bus 2.0 is just around the corner and will beat PCI. Not to mention that Intel doesn't know where to take PCI. If I were you, I'd stick to Local Bus, and ISA for a while longer. Alex K.
