I have compiled new network and RAID controller drivers for FC1. The drivers work fine when loading them manually. I created a new FC1 boot disk based on the boot.iso on the first install CD to have them loaded before I install the machines. However, I can not get the drivers to be auto-loaded. When I select HTTP as install source, it asks me which network driver I want to use and when I pick the driver from the list (e1000) it loads it successfully. It gives me a list with my two NICs and asks me which one I want to use for the installation process. So for so good. But how can I get it to auto-detect this? I added the following lines to pcitable, since I did not know whether I had to specify the subvendor/subdevice or not: 0x8086 0x1075 "e1000" "Intel Corp.|82547GI Gigabit Ethernet Controller" 0x8086 0x1076 "e1000" "Intel Corp.|82541GI/PI Gigabit Ethernet Controller" 0x8086 0x1075 0x1028 0x0165 "e1000" "Intel Corp.|82547GI Gigabit Ethernet Controller" 0x8086 0x1076 0x1028 0x0165 "e1000" "Intel Corp.|82541GI/PI Gigabit Ethernet Controller" Which other files do I need to modify and what do I have to enter? Does the last part in the pcitable (the long description) have to match anything in particular to be looked up, or is it just a description?
