BIOS & EC Upgrade
Warning
DO NOT FLASH ANY FIRMWARE IF YOUR SYSTEM IS STABLE AND FUNCTIONING PROPERLY, only consider a BIOS update if you have specific technical requirements or are experiencing any issues
All devices sent after the middle of May seem to have BIOS version of at least 1.04. The only officially supported upgrade way is using Windows, follow the included instructions. Something like Hiren's BootCD could be used as a more convenient option. If there's only ROM file available, download any other BIOS pack in zip archive, which has a flashing utility included. Note that you're supposed to update EC firmware first and BIOS the last.
Caution
After initiating the BIOS upgrade, your PC will reboot and the process will continue in a special interface.
- ‼️ DO NOT turn off your computer or interrupt power
- ‼️ DO NOT press any keys during this process
-
‼️ BE PATIENT, the screen may remain blank for several minutes
In case you somehow managed to brick your system, the only way of restoring it yourself would be direct ROM chip flashing using a programmer, described in this guide.
Compatibility
All AXB35 firmwares should be compatible across AXB35-based devices, allowing you to flash any OEM BIOS regardless of the original manufacturer. However, proceed at your own risk as this practice is not officially supported. Technically it shouldn't even be possible to flash incompatible firmware because it should have a different ROM ID. Currently, we have several confirmed successful cases of flashing GMK BIOS onto a FEVM and Bosgame PCs without any issues.
In general, GMK's BIOS is considered to be the best one so far (while still being very limited).
Debug Mode
A debug mode can be toggled by pressing ALT+F5, saving changes and rebooting. Enabling the mode adds a second "Advanced" tab that contains a lot of additional options, as well as some additional settings in the existing tabs. However, some of them are glitchy or don't work at all. In some cases changing these can even lead to your system not booting unless you erase your settings by removing the battery. All in all, it's not recommended to mess with the debug mode without a particular reason.
