Hi,
Thank you for your reply.
root at me:~# /proc/iomem
00000000-0fffffff : System RAM

b0510000-b0520000 : ext sata pci memory space
d0000000-d8000000 : ext pci memory space


it says system RAM which is NOT physical RAM size.
Is there any way how to find out where RAM starts?

from dmesg i found only
kernMemSize : 148 MB

Thanks
