hi
well i am not able ot understand this... there are lot
many more problems
/proc/iomem
00000000-0009fbff : System RAM
0009fc00-0009ffff : reserved
000a0000-000bffff : Video RAM area
000c0000-000c7fff : Video ROM
000f0000-000fffff : System ROM
00100000-077effff : System RAM
00100000-00250d5b : Kernel code
00250d5c-0034ac43 : Kernel data
this is just a brief..... System RAM what does that
mean? the range can just point 65K of RAM? what about
rest? so what that means?
also,
on a 32 bit proceesor we can at the most have a access
to 4GB of area as we have that many address space.
well some what it look stupid but then also asking
some where this blunder i have to clear, that how it
access the hard disks which is of much high capacity?
thanks again
ankit
