[J3455-ITX new BIOS finally released]

Thanks for the feedback!

I don't have a Windows PC, all BIOS version that I have processed so far have been with the same tools and copied to the same USB stick. However, I may try another USB stick (or reformat it) since I experienced dock station crash while the USB key was plugged into it and mounted in my PC. I did run fsck on it (from a Linux system) and if the BIOS flashing utility VERY is touchy, this could explain why it does not see the other BIOS versions. But sincerely, I doubt this is the case.

I will try and let you know.

 

In the end, note that I have the same problem than fenguoerbian.

And note also that my current BIOS version (v1.60) is not available online, likely meaning it is crappy.

Thank you.

This is what I did: all of the BIOS I have come from the same page: https://asrock.com/mb/Intel/J3455-ITX/#BIOS

I do really have a J3455-ITX board (=lshw= confirmed it).

Files have been unzipped of course and are all of the same type, according to =file= command:

$ file A*
APLITX1.30:    Intel serial flash for PCH ROM
APLITX1.40:    Intel serial flash for PCH ROM
APLITX1.70:    Intel serial flash for PCH ROM
APOITX1.80:    Intel serial flash for PCH ROM

Only v1.80 is detected by the BIOS.

That is why I am interested in afudos.exe and bootable MSDOS.

Il y a 3 heures, Hostilian a dit :

You don't need to boot to DOS on a floppy drive (the run a BIOS updater) nor update from within the OS anymore. 

When I do that, I can only see v1.80 proposed by the BIOS updater utility. 

In the end I cannot upgrade to v1.80 since one have first to install v1.70 beforehand, but it never shows up even when it is the only BIOS file present in the USB stick.

I thought that using a DOS bootable stick + afudos.exe would allow me to control what can be done (either to install v1.70+v1.80 or to downgrade to v1.30 as some are suggesting in this thread).

More importantly, I have front USB2/USB3 (those from the mobo connectors) that have unstable powering making, for example, keyboard's LEDs to blink!

I have other issues with this motherboard, including "CMCI Storm" reported in system logs.

These issues are the reasons why I wanted to give a try to more recent firmware versions at first.

By the way, with v1.60, I have /dev/dri/ (Debian 10.5 - Linux 4.19).

I wonder how could you have flashed this *UEFI motherboard* with MSDOS.

I used to flash motherboard using Freedos, but it is not possible on UEFI hardware anymore. :(

What is the trick I am missing here? (I left the windows world since so long, ...)

 

I have the same motherboard with firmware v1.60, and like others, it was impossible for me to upgrade to v1.70 (not seen by flash utility), so I gave up with the idea to upgrade to v1.80. However, I am very interested in downgrading to v1.30.

Thanks for your help.
