#PCI/ISA – PCI/EISA
8 messages in this thread
I have two questions concerning PCI Penium machines:
1. Is there a difference in working speed and performance between a
mixed PCI/EISA and a mixed PCI/ISA slot. will a PCI fit in both as
good as possible, will an EISA card fit in a PCI/ISA slot??? will an
ISA card fit in a PCI/EISA slot???
2. how can one notice if the PCI computer is equiped with the latest
PCI chipset from Intel, and not the first set that still has bugs?
Thanks to anyone
Sorry, but Product Support doesn't have a Pentium, not even a little one<g>.
Perhaps someone else will be more helpful about your PCI/EISA/ISA question.

Hi Christophe,
For what I can tell, EISA is a goner. And PCI might go in the same direction.
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.

Yo,
You have no idea what you're talking about. EISA maybe getting a little passe
but PCI is far from being a "goner". Intel had "a" problem with the PCI bus and
not "NUMEROUS" problems. It has been corrected before any of these computers
out there were put on the market. As it is today, PCI is a much better
performer than any VESA bus. The only problem with it is people like you who
just says things like this because you "heard" somewhere. VLB 2.0 is coming out
and it is a pretty good spec. So is the new PCI. I can't say who is going to
prevail because this market is crazy. Specially when people keep saying things
without any technical base.
Will VESA 2.0 handle other peripherals (besides graphics adapters) as well as
PCI? I read some stuff about Vesa 2 a while ago, but can't remember if that
was addressed.

Christophe,
To answer some of question subject 1:
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.

Chris:
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.
Richard,
>> PCI is faster then VLB,<<
I'm not sure if that is always true. From what I have read with comparisons of
similar cards in both modes (PCI and VL), the VL version were actually faster.
