If you boot straight to rommon on your 7600, with a message saying that it is unable to find boot file:
Autoboot: failed, BOOT string is emptyThen first check the boot flash on the supervisor:
rommon 1 > dir bootflash:You will most likely see something along the lines of :
rommon 1 > dir bootflash: File size Checksum File nameNotice that nothing exists on the boot flash. This means you need to boot from an IOS that is installed on one of your disks. First list what is on your disk:
rommon 1 > dir disk0:
rommon 1 > dir disk0: File size Checksum File name 45463592 bytes (0x104aecc) 0x9a2f0302 s720333-psv-mz.122-18.SXD7.binUsing this info, boot via this file:
rommon 1 > boot disk0:s720333-psv-mz.122-18.SXD7.bin
