Hi, I have seen reference to kernel support for up to 32GB on 32 bit x86 platforms, with supporting hardware (some versions of Xeon?). Perhaps I used the wrong search terms, but I could not locate much detailed information on the subject with Google. Specifically, I was told that the kernel could map the memory virtually, but the I/O sub-system could not handle physical I/O to address over 32 bits, thus I/O to high memory was done via bounce buffers (i.e., DMA to low memory, then CPU copy to high). Can anyone point to some documentation on the large memory implementation I can use to confirm or refute what I was told? Thanks, --rick
