ISA - PCI Conversion

If you google for the part and throw on filetype:pdf you can find this, among other things:

Looks like it has a eeprom for configuration.

Depending on what your card does (and how many you want to make) it might be easier to buy something like:

There used to be a deal where you could get those for $99, but even at $150 it's a bargain.

If PLX didn't give you a CD with it all on (I suspect they did), you can download all the required schematics from their site. In my experience they give excellent support.

Can i hardwire the expansion rom address (to the bridge

No, PCI won't let you do that. Though you could write a program to change the address yourself- depending on OS, you might need something like TVicHW to get at the hardware though. You'll also have to check that the address you want hasn't been allocated to something else too. Check out Ralf Brown's PCI programs if you use DOS.

Sorry, forgot to say.... my board loads the OS... no windows, dos loaded by the board. Dos goes in an eprom at the board.

Even today, some bioses allow a PCI network card to boot the system. For this purpose the network card is fitted with an EPROM. Try to find out how that works. Even the cheapes network cards have EPROM sockets. Buy such a card and make it run your software from that EPROM so you know you have working software in your EPROM. Next step is to 'clone' the part of that card that holds the EPROM. A program called PCItree is very usefull for accessing the configuration area of a PCI card.

Yeah, very good idea... thanks I=B4ll give a try on that
