my pc is of the following configuration:
256 MB SD RAM
INTEL i810 Mother Board
Previously, I had 128MB RAM and a few days back I added another 128 MB.... but after i added 128MB linux system behaved erratically.... at times it was reasonably fast while at other times it was agonizing slow...
i used *free* command to check ram... it showed 256MB... but when i booted the system using the following option:
my linux system was really flying... (am using Red Hat 8)
However, if I use any value more than 254 in the boot option... then the system becomes very slow indeed...
can anyone please tell me why linux fails to take 256MB RAM or when it attempts to use 256MB RAM it becomes very slow....
