Hello,
I have a Dell PC, XP Home edition. When I start the PC up the first screen
that comes up states " O S Install mode enabled. Amount of available memory
limited to 256MB. Strike the F1 key to continue. F2 to run the setup
utility." If you hit F1 the Pc seems to work fine but I can't tell if it is
only using 253MB of memory. There is 512MB of RAM installed on this machine.
Any clue why this message is coming up on startup?
 

Have a look.
