Download the SDK files

This topic describes how to download the SDK files needed for installation. You can skip this step if you have physical media for the SDK such as a CD.

YUM automatically downloads most of these RPMs so it is not necessary for you to manually download them.

The developerWorks^® Web site and the Passport Advantage^® Web site provide the IBM-licensed code and its documentation as ISO images. Passport Advantage is an IBM^® Web site that gives you information about software maintenance, product upgrades and technical support under a single, common set of agreements, processes and tools.

To download the SDK perform the following steps:

Create a temporary directory for the images and the cell-install RPM by typing the following commands:
```
# mkdir -p /tmp/cellsdkiso
# cd /tmp/cellsdkiso
```
Download the cell-install RPM from developerWorks or Passport Advantage Web site and place it into the /tmp/cellsdkiso directory that you created in the previous step.
Download the ISO images into the same directory.

Here are the choices for ISO images for each supported Linux^® distribution:

Table 1. ISO images for Red Hat Enterprise Linux (RHEL) 5.1
The Product package contains all the mature technologies in SDK 3.0 plus access to IBM Support and is intended for production purposes.	CellSDK-Product-RHEL_3.0.0.1.0.iso	http://www.ibm.com/software/howtobuy/passportadvantage/
The Developer package is intended for evaluation of the SDK in a non-production environment and contains all the mature technologies in SDK 3.0	CellSDK-Devel-RHEL_3.0.0.1.0.iso	http://www.ibm.com/developerworks/power/cell/downloads.html
The Extras package contains the "latest and greatest" technologies in the SDK These packages tend to be less mature or are technology preview code that may or may not become part of the generally available product in the future.	CellSDK-Extra-RHEL_3.0.0.1.0.iso	http://www.ibm.com/developerworks/power/cell/downloads.html

Table 2. ISO images for Fedora 7
Product set	ISO name	Location
The Developer package is intended for evaluation of the SDK in a non-production environment and contains all the mature technologies in SDK 3.0	CellSDK-Devel-Fedora_3.0.0.1.0.iso	http://www.ibm.com/developerworks/power/cell/downloads.html
The Extras package contains the "latest and greatest" technologies in the SDK These packages tend to be less mature or are technology preview code that may or may not become part of the generally available product in the future.

You can verify the integrity of the files using the md5sum command. Checksums are provided on the download Web page.
