6500 not booting neither from bootdisk or disk0: with illegal opcode error

[krir]

Hi

One of the 6500 was going in bootrom mode,  so I have formated the flash disk using the other Cisco 6500 switch and copied IOS file to the  boot disk. But the 6500 booting failed with the following error

rommon 1 > boot disk0:/s72033-adventerprisek9_wan-mz.122-33.SXI9.bin
Loading image, please wait ...

Initializing ATA monitor library...

*** Illegal Opcode Exception ***
PC = 0x801060e4, Cause = 0x28, Status Reg = 0x30409003

monitor: command "boot" aborted due to exception

Awaiting your kind revert

This looks like the IOS is corrupt.

Check the bootdisk/bootflash for any crashfiles. Might also be a corrupted IOS. Best way to confirm is to take a flash from another working 6500 after testing SXI9 to be working over there and use the same disk in this device. Not the easiest of methods

Check the MD5 hash with YOUR file against the Cisco website.

Use the command "verify /md disk0:IOS.bin".  At the end of the process is long line of alpha-numeric numbers.  Compare that value against the Cisco website.

If they don't match you may need to download the IOS from the website once again.

Good point Leo.
