Hi,

Sorry if this is in the wrong section to post this thread but I though it wasn't really asking how to implement something or a design issue. In my mind this is closest to an announcement so I put it here.

At the moment my bootloader scans the PCI bus and reads the vendor and device id from each device. These are then compared with a list that it loads and it sees whether they match. Using this method it decides what type of card it is i.e. an rtl8139, an ne2000, a sis900 etc. I have now got to the stage where I need to start adding more device and vendor ids to the file it loads. Would it be possible for you to provide me with the device and vendor ids for cards that you know are rtl8139s etc. I know the pci database exists but there are many network devices where it does not state rtl8139 etc. and this therefore means I can't use them. I will put this list up somewhere online when its been generated so that everyone may benefit from it.

Also, if anyone has an easier method of identifying whether a card is an rtl8139 or ne200 etc. than comparing its device and vendor id with a list then I would be very grateful if you could share that with me. I'll put up the list I currently have here.

Here are from my rtl8139 list

Well Im not sure of any other method but there are a few things you can do to speed up the search.

- Group Device IDs by vendor. From the looks of it vendors only make one of the 7 so check the vendor numbers and then if it matches look at the dev ID to confirm.

- Use a smart searching method. It may take a little more code to accomplish and a little extra setup but a binary tree search method will yeild much faster searching than a simple list search. O(log n) is much better than waiting on a O(n)
