Linux instructions 1. Install syslinux/isohybrid If you would like to boot the from a USB stick then you can make the ISO bootable by installing syslinux. # zypper in syslinux # isohybrid openSUSE-12.1-DVD-x86_64.iso Once completed just follow whichever set of above LiveUSB instructions you like, and take care to read the Booting from USB-DVD section below afterward, like the instructions below.

2. Find Block Device

Plug-in your USB stick and find what "/dev/disk*" it is mapped to by opening Terminal and executing:

# diskutil list

This will print out the list of currently mapped devices/partitions. Find the USB using "NAME" column. Then note the corresponding /dev/disk*. For example:

/dev/disk2
   #:                       TYPE        NAME                    SIZE   IDENTIFIER
   0:                       FAT32                               2.0 GB   disk0
   1:                                   USB2                    2.0 GB   disk0s1

In this case /dev/disk2 is the one we want.

Or:

Plug-in your USB stick and find it executing:

# fdisk -l

You can see the results:


Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x271ebf44


   Device Boot      Start         End      Blocks   Id  System
/dev/sda1            2048     3074047     1536000   27  Hidden NTFS WinRE
/dev/sda2   *     3074048   488396799   242661376    7  HPFS/NTFS/exFAT


Disk /dev/sdb: 16.0 GB, 16022241280 bytes
82 heads, 18 sectors/track, 21201 cylinders, total 31293440 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xc3072e18


   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *        8064    31293439    15642688    c  W95 FAT32 (LBA)



where your 16 GB flash device, in this case, is /dev/sdb1

3. Unmount USB Stick

Unmount the USB stick

# diskutil unmountDisk /dev/disk*

Where /dev/disk* is the one you have found in previous step.

4. Write ISO to USB

Write the content of the ISO file:

# sudo dd if=/path/to/downloaded.iso of=/dev/disk* bs=1M

Again the /dev/disk* is the same one you have found previously. You will be prompted for the administrator's password.

5. Booting from USB-DVD

Write the image to the USB stick using the Windows instructions above.

• Hit F4, change the installation source to Hard Drive, but leave all fields blank and hit Enter to close the dialog.
• Type "namescheme=by-label" into the boot options for "Installation" and start the installation; you should go straight to the installer without a hitch.

openSUSE USB Install

Installing openSUSE 11.4 using a USB drive.
Download the openSUSE-11.4-DVD-x86_64.iso file for 64bit x86 system. I used another Linux system to prepare the USB drive, you can also boot from a Linux live DVD. Need at least an 8GB USB drive, openSUSE 11.4 iso is 4.3GB.
1. Erase USB drive using dd:

Use dmesg to identify the USB drive device (example: sdb). Or (a better option):

Para saber qual é essa identificação, com o pendrive conectado no computador, digite no terminal o comando:

# fdisk -l

O resultado aparecerá na janela do terminal. Veja a imagem abaixo que mostra o resultado do comando fdisk e na outra imagem o resultado do comando dd. O pendrive, nesse caso, é o ultimo da lista, sendo o dispositivo /dev/sdc1.

O comando, neste exemplo, ficaria assim:

# dd if=openSUSE-11.2-KDE4-LiveCD-i686.iso of=/dev/sdc bs=4M
# dd if=/dev/zero of=/dev/sdb bs=65536 count=10000
2. Use zypper to update the syslinux:
# zypper in syslinux
3. Run isohybrid, isohybrid is availabe with the updated syslinux:
# isohybrid /path…/openSUSE-11.4-DVD-x86_64.iso
where path… is the directory location of the openSUSE iso.
4. Write the content of the iso file to the USB drive:
# dd if=/path…/openSUSE-11.4-DVD-x86_64.iso of=/dev/sdb bs=1M
Boot from the USB flash drive to install openSUSE 11.4
Note: You’ll get a warning when you run isohyrid:
Warning: more than 1024 cylinders (4403).
Not all BIOSes will be able to boot this device.
The cylinder=1024. It should be ok to procede if you have a newer system (south bridge that support SATA). The section of isohybrid perl scripts that displayed the error looks like this:
$c = int($imgsize/$cylsize);
if ($c > 1024) {
    print STDERR “Warning: more than 1024 cylinders ($c).\n”;
    print STDERR “Not all BIOSes will be able to boot this device.\n”;
    $cc = 1024;
} else {
    $cc = $c;
}
