Amount of available memory limited to 256 MB
I am using Dell PowerEdge 1400SC. (It’s work for PowerEdge 1500SC as well.)
When I boot the server after pluging in another two 256MB Memory into the mother board.
This message was display.
Amount of available memory limited to 256 MB!
Strike the F1 key to continue, F2 to run the setup utility.
After couple minutes searching on Google, I found the answer already.
This is due to “OS Install mode” is enabled.
The solution is
Press F2 enter to BIOS setting
Turn off “OS Install mode”
Save Changes and Exit


GREAT…….Its working well

IT WORKS!!! with our Dell PowerEdge 6400…
“OS Install mode” should be turned “OFF” to reflect the real memory (RAM) size at boot time…
Thanks a lot!!!
