Hi I have posted several time in this list my problem concerning new monitor. Indeed i want to kickstart some machine which have monitors that are not in the MonitorDB file which is present in the netstg2.img file. The installation run well, the monitor are dccprobing well but the final configuration doesn't take into account the value that are return from the dccprobe but other value that are far more conservative ( especially for the hsync vsync parameter ). I discover that the monitor must be present in the MonitorDB file in the netstg2.img. Here i will describe how to "upgrade the file". -first mount the netstg2.img file mount -o loop /var/ftp/pub/distrib/mci-9/RedHat/base/netstg2.img /mnt/loop -second make a copy of the /mnt/loop directory mkdir /tmp/loop2 rsync -av /mnt/loop/ /tmp/loop2 then modify the file in /tmp/loop2/usr/share/hwdata The first thing to do is to copy the following files from the hwdata from rawhide. Then you get the uptodate files Cards MonitorsDB pci.ids pcitable After you can edit the MonitorsDB file for adding your monitor. for example i had the following line for my screen Maxdata Computer; Maxdata Belinea 10 17 75; max06aa; 31.0-83.0; 56.0-75.0; 1 As far i can see the important thing is to put a real vesa id You got all these informations by launching ddcprobe in the F2 console during installation. The final step is to create the updated netstg2.img u should use mkcramfs. Here in my example i use umount /mnt/loop mv /var/ftp/pub/distrib/mci-9/RedHat/base/netstg2.img /var/ftp/pub/distrib/mci-9/RedHat/base/netstg2.img.old mkcramfs /tmp/loop2 /var/ftp/pub/distrib/mci-9/RedHat/base/netstg2.img Now you have an updated netstg2.img that contains your monitor. and it works for me. I hope it will be useful to other person and any comments are welcome
