BIOS Eprom

goodmorning ereryone,

I’ve aspireone 110, 1,5 gb ram and sata 250gb.

Can someone show me the eprom bios on the mainboard to try upgrade directley, because my last recovery update by pendrive usb did’nt work.
Black schreen always and power led blinking.

I'd like flash it directly

Thank’s in advance.

 

Even if someone points it out to you on the mobo.. how the heck are you going to update it again??
Swapping the chip is not possible as its not on a socket.
And I dont think imposing your hands on it will do the trick!

 

unsolder it and hook it to a computer. Use a bios program or bios flasher to flash it.

I think the bios eprom is somewhere in the upper right hand corner. There's more information in a thread called "2.5GB ram" in the hardware section.

 

so... you would unsolder (assuming you have a proper solder) and then solder back?
and how would you "hook" it to a PC??
ROFL.
Good luck mate.

 

I have an EMP20 which is a "flasher". There are several other makers out there for programming chips. The problem with my EMP20 is that the company went under and it is not supported. I did "look" at the BIOS with my EMP20 but it was using a different chipset. And that would worry me when flashing it. Although, If you know what the checksum is when it is programmed if the checksum is correct then all is good. I did cross reference some other chips but of course, non are supported by the out dated EMP20. I do not remember what I used for a device but I think it was an Intel 1mb chip or something and did come up with the correct checksum.

this is what I have:

 

Oh, BTW, I believe it is P010 which is to the left of the cmos battery in the picture below (just to the left of the little coil).

LARGE PIC

 

hi garrettp,
you believe o confirm that ?

P010 ?

Someone else can confirm that ?

thanks in advance

 

The only way to really confirm would be to remove that chip and see what the checksum is. You would have to know what the checksum of the current BIOS thats on it of course.

I never took a close look at what that chip is. If you looked in the 2.5g thread it is stated in there what chipset the BIOS is on (windbond 25 something).

It is stated what the chipset is but not really sure on if that is the proper one on the board but I think someone may have confirmed it in the 2.5g thread.

BTW, what are you using to remove the chip and what are you using to flash the chip?

good luck

 

I know i,ve to find a eprom named W25X80VSSIG.
have you never meet something similar on main board?

that eprom is the BIOS

 

WAIT WAIT .....

FIND IT !!


SOMEONELSE CAN CONFIRM IT ??

 

That sure looks like it to me. I never looked for it when I had mine apart and now I am glad, I never would have found it on mine. Check out the link below, I do not have the same stuff that you have lol.
my AA1 BIOS chipset

 

That is what I have, except it is labeled W25X80VSIG

Does not look too hard to unsolder or maybe you can solder leads to it in place and flash it.

 

I have three revsion F motherboards and they all have the Winbond chip.

What revision Motherboard do yo have Garrettp, that has a EoN chip ?

 

Rev: G pic is HERE

 

Did you try to peform Crisis restore? The crisis loader is afaik imposible to break. You need to put USB stick in and press FN+ESC, it will get you a menu which allows you to reflash the "bios", previously blown away. Usally this MUST work, no matter if the Bios flashing previously went bad.

Also please note, InsydeH20 is NO Bios in traditional terms! It's basicly a EFI running a BIOS legacy emulation for your hardware.

 

I could not for the life of me get the FN+ESC to work for me personally. I am not wondering if it has to do with me using a USB SD card reader vs a real memory stick (dedicated)? I have not use for a memory stick but I wonder if that is the cure.

 

If I boot the my AAO with this combination (I foudnit in the service manual) I see EFI loading and than falling back in the BIOS legacy module which boots system instead of getting the splash screen, so it must be definatly recgnized even on the new systems.

I am currently reversing the EFI FD update file (http://hax0rpedia.com/index.php/AAO_InsydeH20_EFI) if I find anything which might be helpful on this topic I will let you know.

 

The way you did it worked for me. I always flash Bios with an SD card.

 

Well some ideas:

EFI does not know FAT32, only FAT16. If Crisis is working the same, try using a FAT16 FS instead of FAT32 or even NTFS (etc.). Also try to put thumbdrive on USB0, which shuld be the first choice. I guess this is the USB port on the left (?).

Edit (Hint): WTFlolroflbbq ... Logins for Acer Service Desk are floating around the net, you will find the latest service manual for your model there Data leak...

Maybe this helps.

Update: After testing I can confirm that this process (Flashit.exe + FD file for your Netbook) works. I killed mine and restored it just a minute ago x)

 

please,
my original post was for those doing the procedure as you described have had big problems.
we know that the procedure is correct.

we would just flashing the rigth eprom.

have you any suggestions ?
