I've followed the steps to update to BIOS 3309... Macles and other blogs that I've come acrossed. When using Unetbooting I get an error on the 3rd step when downloading(the step before reboot)??? I reboot F12 and do not have OPTION 5 (just 1 and 2). Tried this 6 times and I downloaded the file from Macles and Acer site with no luck. I'm using an MP3 player as USB stick??? Could this be part of my problem, the Unebooting seems to recognise the drive. I realise the instructions are very clear, but maybe someone as come across this and know's how to adress it. I researched FAT32 files but I'm not very computer savy, as you can probably tell by now! Thanks for any help, S.
