In IOS boot sequence if the flash is erased, and there is 
no access to TFTP server, and we can't load the partial IOS

Answer
# 1
i am not confrim it is wright or not but letme try amd let 
me know i am wright or wrong

1 downlaod a softwair based tfftp server on your computer 
like TFTPD32 tftp server

2 downlaod the ios image from internet or if you have

3 pweron the switch

4 press the key break

5 load the downladed ios in that tftp server

6 load that ios from tftp to routr or switches


Follow this procedure if you want to upgrade cisco IOS

NOTE :- Before doing any upgrades plesae take a complete 
backup of your cisco device configuration for safer side

Download the Correct version of Cisco IOS for you from here 
http://www.cisco.com/tacpage/sw-center/index.shtml

Write Unsaved configurations

ciscorouter# write memory
Building configuration…
[OK]

Check space on Flash Memory

ciscorouter# show flash

Make sure you have the space left on your cisco device.

Backup Startup Configuration

Setup a TFTP server in the same IP range as the Cisco 
device to backup the configs, IOS image and also for later 
to upload the new IOS image.

testrouter# copy startup-config tftp
Address or name of remote host []? 10.10.10.2
Destination filename [startup-config]?
!!
1278 bytes c opied in 0.100 secs

Backup Current IOS Image

testrouter# copy flash: tftp:
Source filename []? xxxxx-xx-xx.121-x.XB
Address or name of remote host []? 10.10.10.2
Destination filename [xxxxx-xx-xx.121-x.XB]?

Now, Load the new IOS image from the TFTP onto the flash

ciscorouter#copy tftp: flash:
Address or name of remote host []? 10.10.10.2
Source filename []? c3560-ipbasek9-mz.122-40.SE.bin
Destination filename [c3560-ipbasek9-mz.122-40.SE.bin]?
Accessing tftp://10.10.10.2/c3560-ipbasek9-mz.122-40.SE.bin…
Loading c3560-ipbasek9-mz.122-40.SE.bin from 10.10.10.2 
(via 
Vlan1): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!
[OK - 8295106 bytes]

8295106 bytes copied in 124.571 secs (66589 bytes/sec)

Now you need to make sure you are booting with the correct 
version of IOS image for this you need to use the following 
command to set.

testrouter(config)#boot system flash:/c3560-ipbasek9-mz.122-
40.SE.bin

Now you need to reload the Cisco Router

testrouter# reload

After rebooting cisco device with the new Cisco IOS image 
you need to make sure this use the following command

testrouter# sh ver

That’s it now we are using the latest IOS on your cisco 
device

i donot know it will work or not but try it 




try it till then any of the best answer
