Re: Subsystem Vendor ID

["Hayrettin B. Karayaka" <karayaka.1@osu.edu>]

Well,  my PCI rev 2.1. book says Subsystem Vendor ID is designed for card
manufacturers that use same PCI chip. In other words, the Subsystem vendor
ID/Subsytem ID registers are used to uniquely identify the add-in card or
subsystem that the functional device resides within.

So we are not trying to hack anyboy's Vendor ID and change it, we just
wanted to figure out a way to put our signature in the proper place.

FYI, the PCI chip has no EEPROM support and it's a PC-Card controller.

Thanks for all the great advice
