Desperately looking for this, any version.
I've found one here https://www.retrospace.net/download/Drivers/T … ios_upgrade.htm but its a dead link, i have emailed the owner to see if he can send it for me.
I have tried with the 50CT BIOS file i have but i cannot get past the 'Ready for BIOS update' screen, exactly the same issue as this guy had https://youtu.be/kMCHB-ajdJo?t=499
The floppy drive just keep spinning. He fixed it by using another Libretto mainboard 🤣, i dont have one of them 😀
You could try the archived bios from here. It has a different name, but worth a try?

AMAZING! Many thanks 😀 I'll try these.
Sad to say the same thing, GHGBIOSA and BIOFCE6T written to a 720k disk, power on Libretto with F12, update BIOS screen displays, 1 beep, insert disc into PCMCIA floppy drive, press any key, disc drive makes a read noise, but then just whirs, another beep, screen goes black, waited 5+mins.
I've attached the Toshiba PCMCIA floppy drive to my windows XP machine, and although it shows as a 5 1/4 inch floppy, and takes an age, it does read the disk and whats on it, so i'd say the drive it operational.
Does anyone have a video of whats supposed to happen when updating the BIOS of a Libretto when using the F12 method?
Have you tried making a floppy using the 1030d640.exe from the same self-extracting file? It needs a 1.44 MB floppy and you run it with '1030d640.exe a:'. It seems to create a bootable floppy with those two files in it, which could be critical for the BIOS update. After that I'm really out of ideas.

Yep, you run that, it put the files onto a 1.44mb floppy, you then have to take CHGBIOSA and BIOFCE6T and put them onto a 720kb floppy.
