Hi, I'm trying to create a customized FC3 Install CD because of driver problems with an IBM HS20 BladeCenter. I've had no luck at all so I've taken a step backward to try and locate my problem. To start with I'm attempting to remake FC3-i386-disc1.iso. This is what I've done: [iso]# mount -o loop FC3-i386-disc1.iso /tmp/mnt [iso]# cd /tmp/mnt [mnt]# tar -cf /tmp/fc3.tar * [mnt]# cd /tmp [tmp]# mkdir image [tmp]# cd image [image]# tar -xf /tmp/fc3.tar [image]# find ./ -name TRANS.TBL -exec rm -f {} \; [image]# mkisofs -R -J -T -r -v -l \ > -b isolinux/isolinux.bin \ > -c isolinux/boot.cat \ > -c isolinux/boot.cat \ > -no-emul-boot \ > -boot-load-size 4 \ > -boot-info-table \ > -V "FC_3 i386" \ > -o /tmp/output-FC3-unchanged.iso \ > /tmp/image INFO: UTF-8 character encoding detected by locale settings. Assuming UTF-8 encoded filenames on source filesystem, use -input-charset to override. mkisofs 2.01a34 (i686-pc-linux-gnu) Scanning /tmp/image Unknown file type (unallocated) /tmp/image/.. - ignoring and continuing.

When I burn the resulting iso file (output-FC3-unchanged.iso) I get a disk that initially boots up but is unable to locate the CDROM drive. Any ideas of what might be causing the problem?
