is prr running?
if not, try manually then

in dos mode, go to the mod folder and type commands

prr
---it may say Ready to flash, then---
fpt -f bios.bin -BIOS

if no go, upload a picture of the error

After ready to flash, next command is

fpt -f bios.bin -BIOS,

If you still get error, sorry, it's not possible to flash your BIOS using software, only external EEPROM flasher
