I also posted this one under "Notebook Bios Problems" which might not be the correct place. Anyway here it is for you to see and maybe you can learn from my experience.
Have done a VISTA upgrade with Acers upgrade DVD.
It recommended to upgrade the BIOS - after doing this notebook is dead.
(1 long and 2 short beeps).
If I want to flash a new BIOS with Crisis method which BIOS should I use i.e. how do I know if I need the AT or UMA version - how to verify this on the notebook (my version is 1642 ZWLMI)?
I would very much appreciate some help on this - thank you
LATEST NEW - it WORKS AGAIN:
I was a little bit worried when I started but later I was all smiles
So a BIG thanks to everyone who posted possible solutions here in this forum:
1: I bought a NEC model UF0002 USB floppy Disk Drive Unit.
2: Downloaded the zip file from the ACER homepage with the BIOS
(chose the one that should be the correct version for VISTA:
It contains 2 WHP files: ZL9A3A24.WPH and ZL9I3A24.WPH as I
learned from NoClaim's post I chose the ZL9I3A24.WPH.
3: Downloaded the zip files with the Crisis recovery zip-file (See d0gi's
post: http://www.rechner.org/b1800.html ).
4: un-zipped the files
5: copies the file ZL9I3A24.WPH into the crisis directory - deleted the
BIOS.WHP that was allready there. And renamed ZL9I3A24.WPH
6: ran the WINCRIS.EXE program (did an unbootable format of the floppy)
7: I now had a recovery floppy.
8: all steps above obviously done on my desktop PC.
9: removed battery from my ACER 1640Z laptop
10: unplugged powercable.
11: inserted the USB floppy in one of the USB ports on the laptop
12: pressed the <fn> and <esc> keys
13: plugged the powercord
14: Turned on the laptop
15: waited a bit - lights came on on the laptop (no beeps)
16: waited a little longer and the light on the floppy came on
17: waited still a bit longer until I could hear the floppy was working
and then I let go of the keys <fn> and <esc>
18: after a while there was no activity on the floppy any more and
shortly after the laptop shot down.
19: the laptop started up again on its own and IT WORKED
20: THE LAPTOP IS BACK AND THANKS TO ALL OF YOU I SAVED A LOT
This worked for me and only cost me £5, Here is the web sit i got it from
Hope it works for you

Tips for a great answer:
go to the acer web site, they'll have the bios and the instructions.
follow them precisely as this is a good way to screw up your laptop. but if you do it correctly, it's not terribly hard and has real benefits.
use the support link or download link, find either bios or your model and then the other.
I wouldn't suggest using any beta bios as they sometimes need to have bugs worked out first.
if you do decide to update the bios
Connect a USB flash drive to the USB port on your Acer. Send all of your files and folders to the flash drive for backup purposes.
Take out your flash drive and reboot your machine. Continue to press "F2" on your computer until your BIOS screen comes up. Check the version of BIOS that your laptop contains, write it down and then reboot your machine.
Go to the Web page for Acer support (see Resources). Click on "Drivers and Downloads" and then "Netbooks."
Click "Aspire One" and click the link for the type of Aspire One computer you own. You can locate this data in the documentation that comes with your Acer.
Click "BIOS." Find the latest BIOS version from the download list.
Click on your "Download" link. Right-click this item and then select the "Extract Here" option. When it finishes the extraction process, double-click on your "WinPhlash" file.
Click your mouse on "Browse." Go to your BIOS upgrade folder and click on the file that ends in .wph. Click your mouse on the "Open" option.
Click on "Flash BIOS." Reboot your machine and then push "F2" repeatedly to start your BIOS.
Push the "F9" key and then "Enter." Reboot your Acer to finish the process
be very careful any mishap can totally screw up your computer and make it unuseable
hope this helps

Shut down your computer. Check your computer manual for the key stroke to get into your BIOS. Typically it is your "F1" or "F2" key.
