BASIC KNOWLEDGE
What is BIOS? |
BIOS(Basic Input Output Syetm) is just S/W like Microsoft Windows. It configures and manages most H/W(CPU,HDD,VGA,Keboard, Mouse, IRQ, SMI...) on M/B before OS booting.
** OS is stored on HDD and BIOS configures HDD before CPU use it. You could see below screen before booting to OS. CPU can not work without S/W code. So, below screen is result of running of some S/W. This S/W is BIOS and all M/B has a BIOS without exception. A BIOS is stored in some device on M/B ( like Windows on HDD ). And this device is FLASHROM and it has small capacity(256KByte~16MByte) for storeing BIOS.

What is Flashrom? |
Flashrom is just similar device with USB flash memory. It keeps a BIOS code in power-off state like USB flash memory or HDD. Different points are just it is connected to M/B via special interface that is not USB and they has special mechanical package. This special interfaces are Legacy, FWH, LPC, SPI. And special packages are DIP32,PLCC32, DIP8, SOP8/16, TSOP32/40/48. Legacy interface flashrom was used in many P3 M/B and older M/B. FWH interface flashrom was used in intel-8xx, 9xx chip-set M/B and many P4 M/B. LPC interface flashrom was used in some notebook and AMD and nVidia M/B. SPI interface flashrom was used in core series M/B and till NOW. And small capacity I2C interface eeprom is used with simple data(~1Kbyte) store. NANO USB Programmer can read and write a data with FWH, LPC, I2C, Legacy and SPI flashrom. And NANO USB Programmer supports PLCC32, DIP8 package. * other package and interface needs a soldering or suitable adapter. |
What is NANO USB BIOS Programmer? |
Flashrom Programmer is special device that can read and write a data in flashrom. And NANO BIOS Programmer supports FWH, LPC, I2C, Legacy and SPI interface flashrom. (There are many other interface in whole world, but typical M/B uses only FWH, LPC and SPI interface flashrom.) You can overwrite a correct BIOS to flashrom that has broken data. or copy BIOS from good one to broken one. Many not working M/B can have a BIOS problem. Sometimes, BIOS can be broken while BIOS update failure or system is unstable. And that M/B can't boot and can't display anything. (Of course, there are many other reason at not worked M/B. In that case, BIOS recover is not solution. ) NANO BIOS Programmer help you repair the BIOS with re-writing flashrom. |
