Description (partial)

After copying the IOS into the bootflash, when configured the boot sequence statement on the supervisor and applied write on the switch. it corrupted the IOS.
I tried to format the bootflash a couple of times but it did not resolve the issue. 
IOS was getting corrupted every time when write is applied on switch after configuring the boot statement.

If the IOS is copied into the bootflash first and then boot sequence statement is configured on the switch then IOS will get corrupted.
Issue found on 03.06.07
