Hi All, I have run into a problem doing koan installs of SL6.2 on machines with onboard igb nics. The : 3.0.6-k version of the igb dirver intermittently drops the connection, causing the koan installation to fail. This problem was fixed in the 3.0.22 version of the igb driver. Unfortunately, I can't upgrade to SL6.4 (long story). So my plan is to replace the igb.ko.gz in images/pxeboot/initrd.img with a 3.0.22 version. My question is how to build a new igb driver which matches the installer kernel in images/pxeboot/vmlinuz Which kernel source should I use? Where is the .config file? Apologies if this is the wrong forum for this question. I have searched the FAQs and HOWTOs on www.sceintificlinux.org but not found anything relevant. Thanks in advance for any pointers! Amnon
