Thanks, Jerry If your goal is to boot off the USB stick and install I have does the following steps recently with a 4gig flash drive: 1. Need to setup the MBR - ex. cat /usr/lib/syslinux/mbr.bin /dev/sdb 2. Use fdisk to create two partitions and make the first bootable: - The first should be 14 megs, fs type should be set to b (W95 FAT32) - The second can be the rest of the drive - Make sure set the boot flag on the first partition (many instructions I found on the web did not mention and it was key) 3. Now you need to dd off the bootdisk.img on the first disk to the first partition: - ex. dd if=/mnt/images/diskboot.img /dev/sdb1 At this point you should have a bootable flash drive and have the option of creating a file system on the second partition then adding the ISO(s) to it along with a kickstart config file. I used the aboved steps on a 4gig stick and was able to put a custom kickstart config file, along with a DVD iso on the second partition.

This is some good stuff I haven't seen documented anywhere. That's a great idea to use diskboot.img on one partition with the install image on a second partition. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
