This announcement includes details on obtaining the beta software, reporting bugs, and communicating with Red Hat and other testers via mailing lists during the beta period.

* Red Hat Enterprise Linux 4 is the first RHEL release based on the 2.6 Linux kernel. We are particularly interested in feedback on hardware compatibility including sound, video, networking, storage device, and USB support on both server and desktop-class systems.

- X11 6.8.1

* This beta release supports a wide range of hardware platforms, including:
- 32-bit x86-compatible (i386/i686)
- 64-bit AMD64 and Intel EM64T (x86_64)

- 64-bit IBM POWER (ppc64)
- 31-bit IBM S/390 (s390)

* This beta release is available in four product variants, all of which are part of the RHEL 4 product family:
- Red Hat Enterprise Linux AS (for x86, AMD64/EM64T, ia64, ppc64, s390, s390x)

- Red Hat Enterprise Linux WS (for x86, AMD64/EM64T, ia64)
- Red Hat Desktop (for x86, AMD64/EM64T)

* Note that the AS and ES distributions contain a superset of the packages found in the WS and Desktop distributions. For a detailed description of the relative features of the AS, ES, WS and Desktop products, please consult:

* Red Hat Enterprise Linux 4 Beta 2 includes support for Security Enhanced Linux (SELinux). By default, SELinux is enabled with a targeted policy that secures key system services. These developer resources provide more information on SELinux:

* Runtime support for 32-bit applications on the 64-bit Intel Itanium2 architecture is provided via the Intel IA-32 Execution Layer. A beta version of the IA-32 Execution Layer RPM package, for testing in conjunction with this beta release, is available at the following FTP location:

Note also that 32-bit compatibility packages for the Itanium2 architecture distributions are now provided on a separate "Compatibility Layer Disc" CD image.

* Red Hat Enterprise Linux 4 Beta 2 adds support for the Intel PRO/Wireless 2100 and Intel PRO/Wireless 2200 family wireless network adapters. Separate firmware packages that are required in order for these adapters to function are available at the following FTP location:

* Red Hat Enterprise Linux 4 Beta 2 includes system-config-lvm, a new tool for configuring Logical Volume Manager (LVM).

* For the 32-bit x86 architecture, Red Hat Enterprise Linux 4 Beta 2 includes an optional kernel known as the hugemem kernel. This kernel supports a 4GB per process user space (versus 3GB for the other kernels), and a 4GB direct kernel space. The hugemem kernel is required in order to use all the memory in 32-bit x86 system configurations containing more than 16GB of memory.

* For support of raw devices using raw(8), a newer util-linux package than that included on the Beta 2 CD images is required. util-linux-2.12a-16.EL4, which includes raw(8), is available via the beta channels on Red Hat Network.

* Note that specific features, packages, and naming are subject to change before the final release.

The supplied beta packages and CD images are intended for testing purposes only. We ask that you report bugs in the Beta 2 release as soon as possible, so that fixes can be included in the next beta release.

Please remember that this early access software is not supported and is not intended for production environments! Please do not publish any benchmark or performance results based on this beta release. Upgrades will *not* be supported from this beta software to subsequent beta releases or official releases.

Red Hat Enterprise Linux 4 Beta 2 is available for download via FTP and Red Hat Network.
