Depends on the CPU and chipset on the motherboard. We've had great success using AMD Opterons and AMD 8100-series chipsets, using the software and hardware re-mapping settings in the BIOS to map the PCI bus/device memory regions above the 4 GB boundary. BIOS count of RAM shows 5120 MB on systems with 4 GB of physical RAM. Kernel shows 4 GB of usable memory space. -- Freddie Cash, LPIC-2 CCNT CCLP Network Support Technician School District 73 (250) 377-HELP [377-4357] [EMAIL PROTECTED]
