blind flashing truely explained in full for the aspire one

[Stinky]

this isnt my work. I found it after corrupting my bios somehow, was playing with slax, did a reboot and whammo, the dreaded no led, black screen, oh crap my lapytop is dead deal.
here is how I fixed it, the trick I hadnt seen mentioned anywhere else was the second touching of the power button. no floppy usb needed, usb stick worked great!

Acer Aspire One BIOS Recovery
The AA1 has a built-in BIOS recovery routine, making it possible to flash the BIOS even if the system doesn't boot anymore. It's only meant for emergencies and may void your warranty, so use at your own risk.

Follow every step carefully!

First format an USB stick with FAT.

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.

Turn the AA1 off, make sure both battery and AC adapter are connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds, the power button will be blinking. Press the power button once. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the AA1 will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.



that little find made my day!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Stinky]

it should be a sticky and yes I know the source, I didnt want to post outside links. seems it is the best way to deal with dead unit from corrupt bios, that was what I was hoping to share.

[tot31]

If you know the source then you should give the full credit to the original person i.e by giving out the source.....

[Stinky]

lol did you not read my posts? I said it wasnt my work in first post, I also stated I didnt want tp post a link. if you really want to split hairs, the source didnt come up with it either, acer did. do you think its a fluke the bios can be fixed in this manor?
if your a mod here, well you just put a big sh&t spot on this forum for me. I thought this was a great find aswell, this forum. if your not a mod, then kiss off, I am not here to impress you. this was not a "stunt". your stupidity shows volumes when making a statement such as that. stunt my a%%. I would have posting in front page if I were looking for flaming glory as you have pictated my attempt to help.

Please Help Me

When I received my AA1 I had put a supervisor password in the Bios... Ther is no prob beacause i found the way the rewrite it using the caps lock. And after i had fixed also a user password.

I had after that made a lot of change in my setup and i had done lot of test for changing the password (i'm a french please excuse my poor english) of the supervisor ; and those tests works.

After that i had use only my user password when i boot. And because I have done so many change in my Supervisor password in the Bios, and i after more than a week i don't use it (using only the user passw.) Since i don't remember my Sup. Passw....

Big problem, but i could go in the BIOS because i remembering my User passw.

After reading eveything regarding the blind flashing, I just decide to flash my BIOS.

Before my BIOS was 3109, now it's 3304 .... BUT the Sup. passw. is still there !!!

How could i remove it ???

I just found this INFOS why they use JAL90x64.fd in place of yours code ?
What's is truely need in this USB flashdrive ?

BIOS Recovery by Crisis Disk
BIOS Recovery Boot Block:
BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS
initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous
BIOS flashing process failed.
BIOS Recovery Hotkey:
The system provides a function hotkey: Fn+Esc, for enable BIOS Recovery process when system is powered
on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery
present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot
Block.
Steps for BIOS Recovery from USB Storage:
Before doing this, prepare the Crisis USB key. The Crisis USB key could be made by executing the Crisis Disk
program in another system with Windows XP OS.
Follow the steps below:
1. Save ROM file (file name: JAL90x64.fd) to the root directory of USB storage.
2. Plug USB storage into USB port.
3. Press Fn + ESC button then plug in AC.
The Power button flashes once.
4. Press Power button to initiate system CRISIS mode.
When CRISIS is complete, the system auto restarts with a workable BIOS.
5. Update the latest version BIOS for this machine by regular BIOS flashing process.

I just wanted to say that this post saved me a whole pile of sleepless nights fiddling with my new lappy! 3 days after buying, adding RAM, and trying to tripple boot XP,OSX, Ubuntu, I somehow fried my BIOS...

I realize this wasn't the first post with this information, but still a life saver for me.

I just felt the need to thank everyone submitting useful information in this forum!

Cheers,

Before my BIOS was 3109, now it's 3304 .... BUT the Sup. passw. is still there !!!

How could i remove it ???

From the service guide:

Power Off a system, and remove HDD, AC and Battery from the machine.
Open the back cover of the machine, and find out the HW Gap on M/B as picture.
Use an electric conductivity tool to short the two points of the HW Gap.
Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
Restart system. Press F2 key to enter BIOS Setup menu.
If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.

The "HW Gap" is the two separated triangles to the direct right of the last onboard RAM chip, on the top side of the board.
