**82430NX PCIset (Pentium) NX (Neptune) (82433NX/82434NX) Mar94
***Notes:...
***Info:...
***Configurations:
Parts:
Intel 82434NX (PCMC) PCI/CACHE/MEMORY CONTROLLER
Intel 82433NX (LBX) LOCAL BUS ACCELERATOR
ISA (single CPU):
82434NX + 2x 82433NX + 82378IB
82434NX + 2x 82433NX + 82378ZB
The main difference between the 82378IB and 82378ZB is the number of
PCI masters supported. See the 82378 section for details. The
pairing with the IB variant is unlikely as it was outdated when the
430NX was introduced.
ISA (Dual CPU):
82434NX + 2x 82433NX + 82379AB
EISA:
Intel 82434NX + 2x 82433NX + 82374EB + 82375EB
Intel 82434NX + 2x 82433NX + 82374SB + 82375SB
The main difference between the EB and SB variants is that the SB
includes power management options. It was released later when
various enhancements had been made to the EB variant. See the
82374/82375 section for details. It is unlikely the EB variant is
paired with this chipset as it was replaced by the SB, when the
430NX was being introduced.
These chipsets are often paired with the SMC 665 for I/O support or
the NCR 810 for SCSI.
According to a Usenet post in comp.sys.ibm.pc.hardware.chips from '94,
there are at least 2 revisions of this chipset. The latter resolves
some issues with posted buffered writes.
****Usenet post (11/7/94):
The Neptune chipset is designed for use exclusively with 90 and 99 MHz
Pentium processors (so you won't see 486 motherboards with it, or
60/66 MHz boards with it either). The Neptune chipset has been
through two revisions.
Rev. 1: This chipset was in boards shipped by Intel to vendors up
until about the end of July 1994. It has/had problems with
posted buffered writes, which would manifest themselves most
prominently with SCSI devices (which used this feature
extensively). Recent releases of the AMI flash BIOS which
Intel ships with their boards (the latest is 1.00.10.AX1)
switch posted buffered writes off on the chipset when rev. 1
of the chipset is detected.
Rev. 2: This chipset is in boards shipped by Intel to vendors as of
about mid August 1994. It has no reported problems (and
works well in my system).
Useful Information:
-------------------
How to find out your motherboard PCI chipset revision:
(Requires DOS support to be installed.)
THE FOLLOWING INFORMATION IS SUPPLIED WITHOUT ANY WARRANTY, EITHER
EXPRESS OR IMPLIED, OF ANY KIND. UNDER NO CIRCUMSTANCES MAY I
(PATRICK DUFFY) BE HELD LIABLE FOR ANY DAMAGE RESULTING FROM USE OF
THE INFORMATION GIVEN BELOW. YOU (THE READER) ASSUME FULL
RESPONSIBILITY FOR ITS USE AND THE CONSEQUENCES THEREOF.
The following commands will identify various aspects of your
motherboard PCI chipset. Type each command as it appears (and press
enter, of course). I've tested this on my own motherboard and it
seems to work. Under the result column, '-' means that nothing will
be shown.
Command Result Comments
debug Enter debug.
O CF8 F0 - Open PCI interface.
I C000 86 Chipset manufacturer ID: `8086'
means
I C001 80 Intel, any other value implies
the other
bytes are nonsignificant.
I C002 DeviceID_LSB
I C003 DeviceID_MSB Chipset's ID
I C008 RevisionID Revision number
O CF8 00 - Close PCI interface
quit Exit debug.
The chipset's ID can be 0483 (Saturn) or 04A3 (Mercury/Neptune)
For the Saturn chipset, revision 1/2 is for Saturn I, rev. 4 is Saturn
II. For Mercury/Neptune: revision 1/3 is for Mercury I/II, and
revision 10/11 is for Neptune rev. 1/2.
So that's what I know, as clearly as I know how to say it. If you
have any questions or notice any ambiguities please do let me know and
I'll do my best to correct them. -- Patrick Duffy
