2501 boot from ROM

I just purchased 2 2501 router because I will be taking a course soon for CCNA.

When I boot the routers they load the IOS from the ROM instead of the IOS from flash.  I checked the flash and there is a version of the IOS in flash.  How do I get it to load the flash IOS.  I put the command:
system boot flash filename
in the starup config but it did nothing.
Any help would be appreciated.

so you would do something like this:
Mine is a 2511...

foo-router#dir flash:
Directory of flash:/

  1  -rw-     7842536              <no date>  c2500-is56-l.120-9.bin

16777216 bytes total (8934616 bytes free)
foo-router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
foo-router(config)#boot system flash c2500-is56-l.120-9.bin
foo-router(config)#boot system flash
foo-router(config)#^Z
foo-router#wr mem
Building configuration...
[OK]
foo-router#sh run
Building configuration...

Current configuration:
!
! Last configuration change at 01:20:31 PST Thu Apr 27 2000
! NVRAM config last updated at 01:20:58 PST Thu Apr 27 2000
!
version 12.0
service timestamps debug uptime
service timestamps log datetime show-timezone
service password-encryption
!
hostname foo-router
!
boot system flash c2500-is56-l.120-9.bin
boot system flash

<SNIP>

Once you do that, reload the router and it should boot up via the IOS in the flash.


Hope that helps.

Ok. You got the command inverted.

It's boot system flash

Also, if that's what you typed and it didn't work, try typing:

config-register 0x2102

This set's your router to boot from the flash (you can check what the current config register is by doing a show version.

Cheers,

Andre

Worked like a charm.  I changed the register from 0x41 to 0x42 and now it works fine.

Did you just guess 0x42? Where did you get this value?

I searched for config-register.

The above site explains it well.
Thanks again
