1. Change the router’s config register to use the boot system helper.
- Cisco Copy Flash Run. 800 series routers don't support CF, but they do support USB flash. The Cisco IOS can only read FAT-formatted flash drives. The IOS may not recognize the proper size of your USB flash drive. However, it doesn't really matter — you have much more space with today's USB flash drives than you could ever use. While using USB.
- Once completed, view the flash again. Type: show flash. Verify the file is there and the name. Those commands should work, I work on Cisco firewalls mostly shouldnt be too different. I should have also noted that I use a console cable that is usb to rj45 and I just connect a patch cable to a port on the cisco device and the Ethernet port on my.

Step 3: Copy the IOS into Flash: on the switch. This is done with the following command: copy usbflash0:c3750e-universalk9-mz.122-58.SE2.bin flash: This will copy the.bin file on the USB into the flash memory of the switch. If you do a 'sh flash:' on the switch, you will see both of them listed in there. En dir Directory of flash:/. One last option would be copy usbflash0: flash: if you just want to save it to the switch without loading it into the startup or running config.Bradley Selzer CCIE# 60833.

2. Reset the router.
rommon 3 > reset
[Router will restart using the Boot helper image.]
3. Get a USB flash disk drive and format it using the Cisco router.
Cisco Boot From Usb
ROUTER#format usbflash0:
ROUTER#show usbflash0:
4. Take out the USB flash disk and copy the following files on it.
* ROMMON upgrade to support booting using USB Flash drive – C1841_RM2.srec.123-8r.T9
* Cisco IOS image – c1841-ipbase-mz.124-6.T1.bin
5. After copying, re-insert the USB disk back to the router.
ROUTER#dir usbflash0:
Directory of usbflash0:/
1 -rw- 876981 Aug 29 2008 14:58:02 +00:00 C1841_RM2.srec.123-8r.T9
2 -rw- 15723844 Aug 29 2008 14:14:40 +00:00 c1841-ipbase-mz.124-6.T1.bin
1031503872 bytes total (1010958336 bytes free)
6. Upgrade the router.
ROUTER#upgrade rom-monitor file usbflash0:C1841_RM2.srec.123-8r.T9
This command will result in a ‘power-on reset’ of the router!
Continue? [yes/no]: y
[Router will reload.]
7. Return the config register back to the default setting.
