Hi all, I have encountered this problem. I have a PC with Asus A8N-SLI Premium<http://www.asus.com.cn/products/mb/socket939/a8n-sli-p/overview.asp?model=A8N-SLI%20Premium>mainboard(NVIDIA nForce4 chipset), AMD 4800+ dual core CPU, 4GB memory, and the BIOS can know 4GB memory.Firstly, I install RHEL 4 update 2 into this PC, but in the initialization, the booting can not continue. it prompt *kernel panic: PCI-DMA: high address but no IOMMU* .I search those info in google, So I install the OS with 2GB memory, and it is sucessful, it can run RHEL 4 with 2 GB, but failed with 4GB. I change the BIOS option, finally the OS can only know about 3GB Memory. Could anyone help me here?Is it problem of Nvidia's chipset? I want to run RHEL 4 with 4GB memory. Thanks a lot.
