RE: Is is possible to receive a cheep SubVendorID?



My assertion is that no one needs to adopt some random
number, because almost all implementations are using
someone else's chipset or IP, and therefore should
be able to get an allocated DID from the chipset or
IP provider.

For a truly embedded system, where no one will be
able to attach a PCI board, then you can do pretty
much whatever you want, as long as you aren't
running any off-the-shelf operating system or BIOS
that cares about 'well-known' Vendor/Device ID's.

If you are writing all your code from the ground
up, and the system is contain in a box with no
standard PCI bus connectors exposed, then you have
complete control over that environment.  As soon
as you buy someone's chipset or IP, or use code
from a 3rd party, though, all bets are off.  At
that point, all kinds of conflicts may arise.

This is the same stock answer to anyone that wants
to do something funky with the PCI bus pinout or
electrical or timing specs.  If it's all inside
your covers, who cares?  Just don't ever plug
some 3rd party card into it.  And, hopefully,
you have that kind of control over your customers
(maybe because it is built into a consumer appliance
'with no serviceable parts' inside 8-).

Dave, Tony,

How about 0xfa3c (dec. 64060) ? Is it busy? I suggest people
who don't feel like paying membership fees for the right to
enter just use this. To further differentiate we would need
some free service for subvendor ID registration; I am willing
to maintain a list of these and keep it public on our website.

I doubt any company will be willing to take this ID once it
is known to be in use  - though not SIG blessed.
Of course I suspect there is more than just one company which would
like to do it just to stop as much progress as they can, but
I doubt anyone would do that openly.  

BTW: We (TGI) do not need a specific vendor ID that badly, our
version of PCI is non-standard (100 pin 0.8mm pitched connector,
with many analogue power supply voltages for nuclear measurement
purposes in a portable environment).
