System: NetBSD chaos-in-motion 1.2D NetBSD 1.2D (CHAOS) #10: Fri Apr 11 18:03:42 EDT 1997 tlyu@chaos-in-motion:/usr/pcmcia-src/sys/arch/i386/compile/CHAOS i386

	The ID codes for the Intel Triton MX (430MX) chipset are
wrong.  ID 0x1234 is the 82371MX, which is the PCI-ISA bridge, and ID
0x1235 is the 82437MX is the host bridge.  This is according to the
documentation on the 430MX chipset on the Intel website.

	This may not be the only error in the pcidevs file; someone
may want to double-check the other IDs.  I don't have time to look up
every single chipset and I don't have access to a copy of the
PCI registry.

	Compile and build a kernel with PCIVERBOSE and look at the
output on a laptop with the Triton MX chipset.
