Hello, As of yesterday, I pulled out my Asus EEE from Asus service center due to very high repair cost. Almost 200USD around 10,000pesos... But.... I am so happy that I had revived my Asus EEE... As from my story, the bootblock was erased and I tried all the tricks for bootblock recovery techniques I found on the net and without luck. It took me two complete days to recover this little machine in a hard way. I opened my Asus EEE PC with the steps here: http://forum.eeeuser.com/viewtopic.php?id=6036Then I saw the BIOS IC and removed it from the board using a soldering iron  From there, I obtained a datasheet from Winbond W25X40 4M-Bit Flash and read and studied all the instructions. From there, I developed the circuit, firmware, and software for flashing.  Here is the software created in C# I had just created this morning to flash my BIOS:  Here is the circuit I created (on breadboard hehe). I used a PIC16f628A (through UART @115200bps) because my parallel port is already damaged. Used SDCC as the compiler.  After programming and verifying using the software I created, I tried to temporarily wire it to see if it works:  And it worked! My Asus EEE is up and running again!  I am so happy!!! ^_^ kung sino man magkaroon ng similar problems, pwede ko kayong matulungan... sobrang taga sa Asus Service Center... |

^ wow galing.  malaki talaga ang matitipid 'pag 'kaw mismo ay marunong magrepair..  'kaw na lang ang mag-repair sa ibang units tapos singilin mo ng halfthe price (100USD).. hehe |

Dapat kasi at least may mga universal programmer na kayo that can specially program/reprogram flash memory chips as well as other rom and mcus. Also learned it the hard way trying to modify my xbox360. But I'm not as skilled and talented as 7 so I opted for the little bit more expensive way ...but hey the investment is worth it.

ano bang nangyari manay7 bat na erase yong BIOS? jusy want to know to avoid it....
nag flash ako ng bios... andami na nyan process na natapos verification ng ROM file kung angkop sa motherboard, BIOS flashing done, then nung nasa bootblock portion na all of the sudden nag hang sa 96% while writing sa bootblock area... around 1hr to 2hrs of waiting, nasa 96% pa rin... there is no way to abort... at based from experience, di umaabot ng oras ang flashing ng bios so I know there is something wrong... nag uusap kami ni sir motion doon sa tipidpc, and yun nga, mahirap pag bootblock portion ang nadale... kahit ang bootblock recovery di gumagana... at kung di nadale ang bootblock, malamang marecover ko pa ito using BootBlock Recovery ng AMI... siguro sinadya ito ng pagkakataon para mapwersa akong gawin yung BIOS programmer na matagal ko ng pinapangarap ayan binigyan ako ng rason para matuloy ang project hehehe magandang learning experience na rin heheheh... |

(bit-banged yung SPI). |

ah..nag bios update ba kayo? nadale rin hp ko nyang mga bios updates nila, nag-ooverheat namn ang lumabas na problema nong hp ko....ang lesson ko don never na e update ang bios yup.. lesson learned talaga .. pero from what happened, ngayon di na ako takot mag bios flash ngayon at mas reliable pala yung flashing sa boot-up ng AMI kasi failsafe daw yun accdg to some websites (alt-F2 sa boot up)... pag nagbad flash ibabalik ka lang daw nya ulit doon sa start-up hanggang sa ma load nya yung correct bios.. at etong method na ito ginamit ko kahapon sa ASus EEE ko para matest ko lang hehehe (bios flash method ng PC, not yung ginawa ko)... successful naman hehehe |
