Procurve 2900 24G Initialisation Problem

Hey I wonder if anyone can help us with the following?

We have a Procurve 2900 24G switch that some time ago had a firmware upgrade done. The newest firmware seems to have been installed to bank 2 of the switches memory leaving an older version on bank 1.

For the first time in awhile we rebooted the switch today and now it appears to be locking up when it turns back on. We have connected to it via hyperterminal and though alot of the text displayed is just garbage it seems clear that it is booting from bank 1 which contains the older (and apparently corrupt) firmware image.

Does anyone know any way of making the switch boot from the 2nd memory bank? or failing that a way to do partial reset so that only bank 1 is reset back to factory settings so we can get onto it and set it to boot off bank 2.

Any help would be greatly appreciated

Restoring a Flash Image

The switch can lose its operating system if either the primary or secondary
flash image location is empty or contains a corrupted OS file and an operator
uses the erase flash command to erase a good OS image file from the opposite
flash location.

To Recover from an Empty or Corrupted Flash State. Use the switchâ€™s
console serial port to connect to a workstation or laptop computer that has
the following:

â– A terminal emulator program with Xmodem capability, such as the Hyper-
Terminal program included in Windows PC software.

â– A copy of a good OS image file for the switch.
Note The following procedure requires the use of Xmodem, and copies an OS image
into primary flash only.

This procedure assumes you are using HyperTerminal as your terminal emulator.
If you use a different terminal emulator, you may need to adapt this
procedure to the operation of your particular emulator.

1. Start the terminal emulator program.

2. Ensure that the terminal program is configured as follows:

â– Baud rate: 9600 â– 1 stop bit
â– No parity â– No flow control
â– 8 Bits

3. Use the Reset button to reset the switch. [Alternately you can power cycle the switch
and hold in the Clear button while the switch powers on to access the boot prompt]
The following prompt should then appear in the terminal emulator:

Enter h or ? for help.

4. Since the OS file is large, you can increase the speed of the download by
changing the switch console and terminal emulator baud rates to a high
speed. For example:

a. Change the switch baud rate to 115,200 Bps.

=> sp 115200

b. Change the terminal emulator baud rate to match the switch speed:
i. In HyperTerminal, select Call | Disconnect.
ii. Select File | Properties.
iii. Click on Configure . . ..
iv. Change the baud rate to 115200.
v. Click on [OK]. In the next window, click on [OK] again.
vi. Select Call | Connect
vii. Press [Enter] one or more times to display the => prompt.

5. Start the Console Download utility by typing do at the => prompt and
pressing [Enter]:
=> do

6. You will then see this prompt:

7. At the above prompt:
a. Type y (for Yes)
b. Select Transfer | File in HyperTerminal.
c. Enter the appropriate filename and path for the OS image.
d. Select the Xmodem protocol (and not the 1k Xmodem protocol).
e. Click on [Send].

If you are using HyperTerminal, you will see a screen similar to the
following to indicate that the download is in progress:

8. When the download completes, the switch reboots from primary flash
using the OS image you downloaded in the preceding steps, plus the most
recent startup-config file.
