Possibly, but without the info I previously requested, I won't be trying to reproduce the problem. e.g. the source file[s] and command[s] used to make your bootable USB stick. I started by listing that: 1. I have a partitioned USB stick, 8G, with a 10M FAT32 partition, and the rest as ext3. 2. Rsync'd isolinux to the FAT partition, renamed isolinux.cfg to syslinux.cfg 3. syslinux to the USB 4. mounted DVD.iso, and rsync'd all of that to the ext3 partition. 5. mounted the second DVD, and rsync'd Packages/* to the Packages directory already there, and so have a 1 DVD, effectively, on the USB. But the question is what image# 1 that it's looking for? It's not trying to look on the USB for an .iso, is it? mark Ah! Take a look at the README in the /images/ directory on the DVD media. The diskboot.img file is a VFAT filesystem image that can be written to a USB pendrive or other bootable media larger than a floppy. Note that booting via USB is dependent on your BIOS supporting this. It should be written to the device using dd. diskboot.img will be the bootable filesystem (for your 10M FAT32 partition). Even tho you rsync'ed (copied) files over, there may be additional pieces missing (for example, the boot block) that are not contained as files per se. Checking the 'diskimage.img' with the file utility identifies the file type as: x86 boot sector, code offset 0x58, OEM-ID mkdosfs, sectors/cluster 4, root entries 512, sectors 24576 (volum es =32 MB) , Media descriptor 0xf8, sectors/FAT 24, heads 64, serial number 0x4d9277bd, label:, FAT (16 bit) It may contain another filesystem after that, but the very first part is a bootblock. Think of 'diskboot.img' as the /boot partition and 'stage2.img' as the / (root) partition, for the Linux operating system environment in which the installer runs. The installer runs in a text-mode for a little bit, but switches over to a graphical (or near-graphical) version on the second stage (where you will see all the packages being installed). The graphical version of the installer relies on this second stage heavily, as the filesystem contains most of the libraries (and all of the fonts) required to run X/Windows environment. Poking around the DVD media, shows a kernel (vmlinuz) and an initrd.img in the /isolinux directory, but very little else to actually run a Linux operating system (X/Windows, and the command line shell interpreters). The second stage contains a pre-built root filesystems that contains the bare minimum to get a system up and running so that RPM can operate, as well as a minimal X/Windows environment for the graphical version of the installer, LVM and other partitioning tools. It may even contain files that are not copied over to the hard drive but are required by the installer itself to run. Hope this helps explain it :-) Cheers!

But the question is what image# 1 that it's looking for? It's not trying to look on the USB for an .iso, is it? That sounds like the bug mentioned at the bottom of the CentOS How-to: http://wiki.centos.org/HowTos/InstallFromUSBkey https://bugzilla.redhat.com/show_bug.cgi?id=568343 (around comment 5) I recently did a network install initiated from a USB stick, but not an install from the stick (I didn't have a Linux machine handy and the 64-bit CentOS 6.2 ISO won't fit on a FAT file system). It is worth noting that the upstream vendor suggests using dd to create the USB media: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/Making_USB_Media.html One would assume that might work if you just needed DVD 1 of CentOS. -- William Hooper ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

as I had no need for LVM on this configuration, but
I have to say, I like Solaris's traditional disk numbering,
/dev/dsk/c0t0d0s0 is channel 0, target 0, device 0, lun 0. the channel
numbering is generally constant in a given system if you don't juggle IO

I also check that the 'from' domain name has an A or MX record. This sort of thing has been standard practice for email servers for at least 15 years.
