I’m looking at a solution for upgrading BIOS to UEFI on a motherboard that doesn’t natively support UEFI. Another user, Rod Smith, replied to a question as to how this would be done stating: “It’s theoretically possible, and may be semi-practical on some computers. What you’d need to do is to merge CoreBoot with a … Read more
I recently manged to brick my acer C710-2384 chromebook a while ago by trying to flash the bios incorrectly. I opened it up, and looked at the motherboard, finding a Macronix MX25L6406E chip. I suspect the issue lies there. I fortunately had an arduino handy, so I threw together a circuit which acts as a … Read more

It is a Thinkpad R52, below are pictures of the motherboard: So, This is the EEPROM: (in a circle), please correct me if i am at wrong and also tell me which sides should … Read more
We have Intel’s board (i7) with Linux, and we need to save some data between power off/on. I thought of using the spi flash for this (there is also eeprom, but for some reason it is read-only!). But I am not sure what is stored in spi flash. Is it that the BIOS is saved … Read more
I have a BIOS file .EXE and I want to extract the bainary file from it to flash it to a BIOS chip directly with USB EEPROM programmer. What I have tried: Extracting the EXE file with 7ZIP or WINZIP to look if there is a BIN file inside it, But I only find ROM … Read more
I need to manage 8 KB of space in an EEPROM. I need to store files in it : of course they’ll be really small. Moreover, we don’t wanna lose any datas already stored if the battery runs out or anything like that. To do so, I’m looking for several filesystems that would be good … Read more
I have a HP Mini that runs Splashtop OS as an instant-on OS and Windows 7 as the main OS. I’ve updated Splashtop through Windows 7 before, so I know it runs on an EEPROM or some other sort of flash storage. Anyone know how to put Chromium OS on there instead of Splashtop OS? … Read more
I was reading about BIOS recovery and ran across the word “programmer”. (No, it’s not talking about people.) What is it referring to? Answer The BIOS is usually stored on an EEPROM chip — an Electrically Erasable Programmable Read-Only Memory. Under ideal conditions you can flash it with a little bit of software. If things … Read more
From http://en.wikipedia.org/wiki/BIOS: BIOS software is stored on a non-volatile ROM chip on the motherboard. … In modern computer systems, the BIOS contents are stored on a flash memory chip so that the contents can be rewritten without removing the chip from the motherboard. This allows BIOS software to be easily upgraded to add new features … Read more
