CPU and Memory Seven Supported Architectures: x86, Itanium2, AMD64/EM64T, S/390, zSeries, iSeries, pSeries. CPU Support on x86 Technical support for more than 2 physical CPUs only on AS variant (may use Hyper-Threading) Up to 32 Physical CPUs with SMP or hugemem kernel. Memory support on x86 Technical support for more than 16 GB on AS or WS Standard i686/athlon kernel: 4GB SMP i686/athlon kernel: 16GB Hugemem SMP kernel: 64GB Preparing to Install Read the RELEASE-NOTES file on the first CD or at Check Hardware Compatibility Redhat Supported Hardware List Hardware compatible with Redhat Linux XFree86 supported video cards. Multiboot systems Redhat Enterprise Linux and the GRUB boot loader can co-exist with other operating systems, including the following: Windows NT/2000/XP/2003 DOS, Windows NetBSD, FreeBSD and other open systems. Two major issues arise when implementing multiboot systems: Partitioning and the boot process. A boot loader such as System Commander or NTLDR is already on the system and will launch GRUB as a secondary boot loader.
