List members,
I have a Dell PowerEdge 6850 running Fedora Core 3 with 12 GBytes of
RAM. Due to limitations of a PCI card I'm installing, I wish to limit
the system memory to just under 4 GBytes using the kernel parameter
"mem". When I do this, the machine boots fine and the PCI card operates
properly, but "/proc/meminfo" and "free" report 2.6 GBytes of available
memory.
Can anyone explain this situation or help me resolve it? If you need
anymore information than I have supplied, please request it.
