Didnt find any clear traces of soldering. the bridges was not present. so i soldered them to be able to update the bios.
i backup the disk, updated the bios, and reinstalled the drive, as it was full of old crap that was very inorganiced(strange how one become more organized 15years later)
now the system is on 5003 bios, and unleashx, uploading back the old games and saves to the disk.
nice to get this old rellic revived after sitting unused in storage for this many years.
yes, i removed the supercap. it had leaked, but no corrosion. i cleaned it with pcb cleaner(Kontakt PCC spray if someones wondering)
main motivation for doing all this is to get the system up to a 2019 level so i can utilize guides and other information online thats more up to date and available.
