how to flash with the updater bootloader (update.exe, UPDBL.NB0, UPDBLHPC.NB0)


DISCLAIMER: NOT RESPONSIBLE FOR ANY PROBLEMS. however, i'm willing to help if i can.



important to know before going on:

when you use update.exe, make sure your bootloader matches the OS you are going to flash.
if you have a hpc2000 bootloader (version 3.x), you must flash a hpc2000 OS.
if you have a ce.net bootloader (version 4.x), you must flash a cenet OS or a hpc2000 OS specifically made for bootloader 4.10.
or flash both the bootloader and matching OS at the same time!


instructions:

1. format a CF card (size at least 64mb) to FAT16 (xp calls it FAT),
2. use normal format (not quick), then unzip the needed files to its root. 
3. you must do this even if the card was already fat16. 
4. if you currently do not have bootloader version 4.10, make sure you also copy the SABOOT.NB0 from the package, to update the bootloader to 4.10.
5. to check your bootloader version, go to control panel on your 900 or 900c, and read NEC firmware info applet.
6. if you do not have bootloader version 4.10, copy the SABOOT.NB0 from the package to the card, this is mandatory.
7. if you already have bootloader 4.10, do not copy SABOOT.NB0 to the card.
8. if every file is copied OK, hardreset the 900/900c by removing all batteries and AC. 
9. do not insert CF card yet.
10. reinsert batteries, put the 900/900c on AC (mandatory), boot to the (old) OS,
11. then insert the CF card and run update.exe on the CF card. that's it. it will take about 6 minutes in total.


troubleshooting:

1. if the update is not done, then try another CF card.

2. if the flashing process of the OS image stops for whatever reason, go and use the C+F keys method (detailed on this site) to reflash.
in this case please do not have a SABOOT.NB0 on the card again!!
