FlashROM Update Sequence
---------------------------------------------------------------------
Following is the sequences to update the SL-5000 FlashROM to the 
latest FlashROM image. MAKE SURE YOU FOLLOW THE INSTRUCTION BELOW 
STEP BY STEP.

1.
For the FlashROM update, CF memory card (32MB or more) is used. You 
must prepare a CF card in order to update the FlashROM. The CF card 
must be formated by FAT16, or must not be re-formatted from the 
default format (since purchased.)

SHARP recommends that you make sure the prepared CF card is 
correctly recognized by the SL-5000D before you atempt to update the 
FlashROM. In order to confirm; 
- insert the CF card, 
- invoke "File Manager" application, 
- change the directory to /var/mnt/cf/
(After invoking "File Manager", tap "upper arrow" icon twice to 
change directory to /root/, and then tap respective directory icon.)
If you see "NotAvailable", the CF card cannot be used. 

2.
Make sure to take back-up of important data onto your PC by using PC 
synchronize software before you start FlashROM update. Data will be 
lost or altered during the update process.
For PC-synchronize software operation, please refer to the operation 
manual of the respective PC synchronize software. Operation manuals 
can be obtained from Operation Manual. 

3.
Once you take back-up of all important data from your SL-5000D, turn 
off the SL-5000D. 

4.
In order to extract the downloaded archive on your PC, create a 
folder, (such as c:\tmp), copy the downloaded archive, and simply 
execute.
Once executed, you will find "romimage" file. Copy the "romimage" 
file to the root directory of the CF Card.
Make sure to remove all other files from the root directory of the 
CF card. 

5.
Insert the CF Card to SL-5000D properly. 

6.
Make sure that AC adapter is connected to the SL-5000D, and is 
actually power supplied.

IMPORTANT NOTICE (WARNING)
MAKE SURE TO USE AC ADAPTER TO UPDATE THE FLASHROM. WHEN CONNECTED, 
THE ORANGE LED ON THE DEVICE WILL TURN ON. Note that If the AC 
adapter is not used, the device will not perform as expected in the 
following instruction.

and orange LED (with "battery" symbol print) will turn on.
When these LEDs are turned on, the update program starts.

IMPORTANT NOTICE (WARNING)
DO NOT ABORT, or UNPLUG AC ADAPTER WHILE LEDs ARE ON. Aborting or 
unplugging AC adapter during the update may cause fault, or damage 
affecting the SL-5000D.
If the orange LED did not turn on, while the green LED is on, the AC 
adapter may not be conected properly. If this status happens, WAIT 
TILL THE GREEN LED GOES OFF, and DO NOT push FULL RESET button while 
green LED is on. ABORTING the update by pushing FULL RESET button 
while green LED is on willcause a serious fault, or damage that 
affects the SL-5000D. 

10.
In approx. 3 minutes, the LEDs will turn off. When turned off, 
FlashROM update program is now completed. 

11.
Pull out the CF card, and push "FULL RESET" button. 

12.
