Here is some ggod info on Cat5k and boot-mode/rommon:
Recovering the Catalyst 5000 with Supervisor Engine I or II, IIG and
IIIG
General Information
The Catalyst supervisor engines I, II, IIG, and IIIG for the Catalyst
5000
family have an onboard Flash that can only store
one system image. The switch runs its image from RAM, so there is no
need
for a valid software image in Flash after
the switch is correctly booted.
The upgrade procedure for these supervisors is pretty safe: a new image
is
first copied into the supervisor RAM, where
its checksum is verified. If this image is declared valid, it is then
programmed into the Flash, overwriting the previous
one. If an error occurs during the download from the TFTP server, for
instance, the current image in Flash is not
modified. Corrupting image on these supervisors happens rarely and is
often
related to a problem on the Flash itself or
caused by an issue during the Flash programming process.
Note: For more information on connecting a console to your switch, as
well
as managing and upgrading software,
please see the Related Information section.
Recovery Procedure
If no image is available in Flash for booting, the supervisor also has
available a very basic software image permanently
stored in ROM monitor. A jumper on the supervisor needs to be used in
order
to activate this image. Once loaded, it
will at least enable the ports of the supervisors and can even recognize
some of your linecards, depending on the
firmware version.
Supervisor type
Jumper
Supervisor I FX (WS-X5005,6)
J25 (boot)
Supervisor I TX (WS-X5009)
J24 (diag on)
Supervisor II (WS-X5505,6,9)
J15 (boot)
Supervisor IIG (WS-X5540)
J8
Supervisor IIIG (WS-X5550)
J2
Step 1: Remove the supervisor engine and identify the boot jumper using
the
above table. There is generally no
jumper connector available on the supervisor, so you need to get one to
establish contact between the pins.
Step 2: Place the supervisor engine back into the chassis and boot up
the
switch.
Step 3: You end up in a boot mode, which is actually a CatOS image burnt
into ROM (firmware). Depending on the level
of this firmware, the switch may even recognize some of the switch's
line
cards:
boot> sh mod
Mod Ports Module-Type Model Serial-Num Status
--- ----- --------------------- --------- ---------- -------
1 0 Supervisor IIG WS-X5540 013447622 ok
2 12 100BaseFX MM Ethernet WS-X5111 003499884 ok
3 12 100BaseFX MM Ethernet WS-X5201 007499406 ok
Mod MAC-Address(es) Hw Fw
Fw1
--- ---------------------------------------- ------ ------------
------------
1 00-d0-63-6a-a8-00 thru 00-d0-63-6a-ab-ff 1.1 5.1(1)
0.5(1)
2 00-60-3e-8e-2b-48 thru 00-60-3e-8e-2b-53 1.0 1.3
3 00-e0-1e-b7-77-68 thru 00-e0-1e-b7-77-73 2.0 3.1(1)
In this example, the two line cards in the switch are recognized by the
software. With supervisors I or II, even though
they are likely to have an older firmware version than has this
supervisor
IIG, the two uplinks are always recognized by
the software.
Using the interfaces available, you now have to get connectivity to a
TFTP
server and perform the usual upgrade.
Step 4: By default, ports are disabled; you have to enable them
manually:
boot> sh port
Port Status Duplex Speed Type
----- -------- ------ ----- ---------------
2/1 disabled half 100 100BaseFX MM
2/2 disabled half 100 100BaseFX MM
2/3 disabled half 100 100BaseFX MM
2/4 disabled half 100 100BaseFX MM
<snip>
boot> set port en 2/1
Port 2/1 enabled.
Step 5: Ensure connectivity to your TFTP server as usual.
Step 6: Once you have downloaded a new image into Flash, you have two
options:
Simply turn off the switch, slide out the supervisor engine, remove
the
jumper, and boot the catalyst normally
once the supervisor engine is correctly re-installed.
Boot the image downloaded in Flash directly from the boot mode
using
the execflash command:
boot> execflash
uncompressing nmp image
This will take a minute...
<snip>
Note: If you boot up the switch this way, remember that until you remove
the
jumper, your switch will always restart
in boot mode first.
Console Download
You can download an image to the supervisor without a TFTP server,
directly
through the console connection, using
the kermit protocol. See the online documentation. This may be useful if
you
can't get any port to be recognized on
the switch during the recovery procedure; however, this method is much
slower than the previous one and should be
avoided if possible.
Hope you all find this info useful!

As I understand it the C5k doesnt have a rom monitor just
try deleteing all the images and see what the box does at
boot nothing !. Not fun when on a customer site at the time.
