Hi leolahoo,
                Thankx for ur kind help,when i am trying to upload via tftp getting error which below config   
             router fe0 connects to symtem via cable. I basically pasted this config into rommon and the image loaded
IP_ADDRESS=192.168.1.99
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=192.168.1.1
TFTP_SERVER=192.168.1.100
TFTP_FILE=c870-advipservicesk9-mz.124-24.T1.bin
tftpdnld -r
TFTP error 1 received (File not foundÌT¸°).
TFTP: Operation terminated
please note windows firewall is disabled.
check this also may be i am doing mistake while assinging ip address.
I put symtem ip address(on which tftp sever is running)
ip address=192.168.1.100
subnet mask 255.255.255.0
default gateway = 192.1689.1.1
On router fe0 interface ip address=192.168.1.1
but i dont understand where i have to assign ip address 192.168.1.99 as i shown above this command is needed  according to syntax.
onemore thing is that when i used below command:
xmodem -c c870-advipservicesk9-mz.124-24.T1.bin
ios downloading  completed but  tell me how to save the image to Flash, after xmodem command
when i put the commands
confreg 0x2101
reset
the router comes in rommom mode again.
I dont know which command save image to flash.
I dont have sufficient privilleges to access bekow link http://www.cisco.com/en/US/customer/products/hw/routers/ps259/products_tech_note09186a008015bf9e.shtml
