Aspire One

Hi,

In the Laptop table the Aspire one is listed as BAD
But as there are so many different aspire one models i wonder if ALL 
Aspire one models are BAD

In my case i have the ZG5 model also known as AOA110 (512MB) and AOA150 
(1GB)
These models have Winbond W25x80 EEPROMS (these are listed as supported, 
all OK

I wonder what's the safest way to try?

Also the link regarding the Aspire One in the Laptop table points to the 
coreboot mailing list, but in the entire post there is NO mention of the 
aspire one.

Eventually i could de-solder the chip and try to flash it in an external 
programmer.

I have 3 of these Acers that could use a fresh BIOS.  (hopefully the 
latest one allows to boot from SD)
Most Aspire One netbooks have BIOS issues and having a tool that doesn't 
require Microsoft would be very welcome.

In software there is a mention of SST2400 and there is no mention of 
Winbond, but on the mainboard there is a Winbond 25x80 chip.

Best,

Wilfried

Why bother? The official BIOS-reflashing method on that generation of
Aspire One is completely OS independent anyway. You just need a
FAT-formatted USB stick and a computer to copy the BIOS image on to it with.

The flash chip shouldn't be a problem, it's the embedded controller
(EC) that can cause problems. If the EC uses the same ROM as the BIOS
and accesses it during a firmware update, the update will likely fail
and your machine may be bricked.
