Flashing the BIOS to Fix a “Bricked” Lenovo Laptop

A few months ago I was attempting to reformat my laptop as a dual-boot machine with both Ubuntu and Windows 10 and I was having issues getting the boot manager to properly detect both operating systems. Shortly after changing a setting in the BIOS related to SATA operation, the laptop suddenly stopped working after rebooting. Powering it on resulted only in a pure black screen where after approximately fifteen seconds it flashed “Lenovo Misto Ontario”, and then nothing. It was true and thoroughly “bricked”.

I tried everything I knew to fix it, including pulling the CMOS battery, reformatting the hard drive, and trying to ‘auto-flash’ the BIOS from a USB drive – nothing worked. I’ve had this little Lenovo S205 netbook for a few years and although it’s gotten slower it’s always served me well.  And since it was working perfectly fine up until it er, wasn’t… it seemed like a waste to just throw it out without trying my best to fix it.

I’m happy to say that I succeeded. The solution was to reflash the BIOS chip with a replacement BIOS I found online, using an open source program called ‘flashrom’ and an Arduino acting as an SPI flash programmer. Here’s how I fixed it.


Controlling Musical Floppy Drives Directly via MIDI

One of my first thoughts on how to improve Moppy was to drive it directly via MIDI. At the moment, the format of serial messages sent to the drive controller is proprietary and requires using the “MoppyDesk” application on your PC to convert MIDI notes into playable pins and wave periods.

What if we can skip the PC altogether and simply plug a MIDI cable into the floppy drive controller? The goal of this experiment is just to see if this is feasible.
