Linux image booted

Wed Nov 20 02:14:56 EST 2002

Hi All

The problem is solved. I am able to boot the linux with minimal ramdisk in
the proprietary board. . The problem was in the rom monitor code. In the rom
monitor code I had given the SDRAM size as 128MB instead of 64MB .Thank you
for all your support.

Regards
Aman
