Acer Aspire One – How to flash bios
Hey guys, Just thought I’d put together a how to on flashing the bios on the Acer Aspire One because I’ve got nothing else to blog about atm and it might help people. Alright, I’ll just do it step by step, and with pictures if needed. Feel free to Digg it.
Requirements: Your Aspire One, a Power point and AC adapter, a flash drive with about 4MB free
- Plug in your flash drive
- Download your desired bios version here http://www.acerpanam.com/synapse/forms/portal20.cfm?website=AcerPanAm.com/au&siteid=8116&areaid=12&formid=3394#results
- Extract the contents of the Bios flash you downloaded in the last step onto your flash drive with a tool such as WinRar
- Download UNetbootin here http://unetbootin.sourceforge.net/ (make sure you get the version right for your OS)
- Run the UNetbootin executable.
- In the “Select Distribution” field, select FreeDOS, and don’t worry about the version
- At the bottom where it says “Type: USB Drive”, leave it, and next to it, where it says “Drive:” Select the drive letter of your flash drive. MAKE SURE you get the right one, or you might muck up your iPod or anything else plugged in. This is what it looks like for me, my flash drive is drive F:\
- Press OK
- When done press Reboot Now – At this point, you may wish to print this page out, or load it on another computer, as you won’t be able to get to it on your aspire one until you’re finished flashing the bios.
- When the computer is booting, keep pressing F12, until the Boot Menu is displayed, Select “USB HDD: (The name of your brand of flash drive)” and press enter
- Wait for it to “Automatic boot” then select Number 5 “FreeDOS Live CD only”.
- You will get a error about a cdrom, but it doesn’t matter. Type “C:” and press enter
- Go to the folder where your update files are (the one with the .bat that you extracted), to do this type “cd <directory name>” without the arrows or inverted commas, so if the folder’s name is update, type “cd update”. Note: Not all flash drives work, if the installation files do not appear, make sure they are actually there, and try another flash drive.
- Make sure you’ve got the power plugged in, orelse the update won’t work.
- Type “dir”, you will see a great big list of files pop up, one of them will have BAT in the second column and it’s name will be something like 3304, which is in the first column, get back to the C:\ prompt by pressing any key, then type in the files name, so in my case “3304.bat” and press enter.
- The flashing will now commence, sit back and relax, although it’s rather fast.
- Give yourself a pat on the back.
All done, you’ve just flashed your computers bios, neat hey?
Companies send out bios updates to fix computer issues, with the one I flashed it fixed things like my wireless card not working, and the screen flickering.
Thanks for reading, if you need any extra help or explanation with the how to, email me at firstname.lastname@example.org.
Also, leave me a comment if I helped you out =]
PS. If the update files don’t show up when you boot into FreeDos, it could be that your flash drive is not supported properly in freedos (or some other aspect of booting it).
Unfortunately the only known option is to try a different flash drive.
If you’re looking to buy another flash drive just for the flash, I know that the HP flash drives work fine and so does the Transcend JF v30.
Thanks to Steve for this information on flash drives.
Feel free to post flash drives that are known to work for this or ones that don’t work for other users to refer to when buying a flash drive.
