"It reads from the floppy like it should but the notebook never returns back to normal"
me interpreting -> action but nothing happen, could not see on display, only noise
extraction from the site
"# Install the bootable BIOS upgrade disk which you previously created to do the original flash upgrade into drive A: and restart the system. If the update failed because you used the wrong BIOS update you should get the correct one and repeat this step. When the computer reboots there will most likely be no video prompts, however you can monitor this procedure using the floppy drive light and the PC speaker. When the PC speaker beeps and the floppy drive light is lit it means that it is currently copying the new BIOS onto the motherboard.
# When the floppy drive light goes off and the PC speaker beeps (twice in most cases) the recovery should be complete. During the update procedure there might be pauses that looks like your computer is doing nothing, if so be sure to wait at least a minute to make sure the update is complete. When you are sure the BIOS update is complete and there is no more activity, power off the computer."
