That should be an SPI flash part. While the soldering is impressive, there may have been an easier way as SPI is typically in circuit programmable.

Yes, it would be expensive for a one time fix, but I suspect someone could come up with a home brew equivalent.

It’s the hangout of Filipino electronic enthusiast and “She” is awesome!

Really nice. I like that it’s more common to see people reversing and modifying complex systems now, even if it’s just a IC flash.

xD
but I think the EeePC has a system of dual bios lol

If the first BIOS is dead
– Must be disassembled for the EeePC press a button not accessible
– Synchronize a combination with the power button and also time
– And (I do not remember to always)
But surely the Bios.ROM on USB / SD for reflash

but! the second BIOS didn’t menu! neither option! because the screen did not use

is too old in my memory
and luckily I never missed a flash

PS: I am sorry for my bad English
I’m french

hello,

thanks for the appreciation…

to Jp1.5,

I tried a LOT of techniques to recover the bios (bootblock recovery, USB with the ROM inside, reading all the articles in the Asus EEE forum) for many days but still without luck… The flashing process hanged when it is currently writing at the bootblock area. from what I read, the method to recover from a bad flash is in the bootblock. however, since the writing at the bootblock area was not completed and was erased, I have no choice but to recover it using a DIY SPI programmer.

if the bootblock area was not erased nor programmed, maybe it will be easier for me to recover this little machine using just the keypress combinations for bootblock recovery or boot through USB with the ROM file. :)

Cute_na_Cute_7 – that’s a very fine hack indeed.

Nice work. :-)

did this project even use resisters? I was thinking of fucking with this atmel eeprom I have and wiring it strait to the printer port. its 5v but I don’t understand what the hell ohms are so I am afraid of blowing it out like you. Something about a law of current or something.

@marcelina

I used SPI on that chip :D

@T&P

if that atmel eeprom is an I2C interface, you may have a look at varieties of JDM programmers + IC-Prog software as I was able to use those programmers before in my projects.

Here are some links on DIY SPI flash programming:
