My Blizzard 2060 has rom version 7.7, I would like to upgrade it to version 8.5.
The needed firmware is available on Aminet.
The Blizzard has 2 eproms (27C256-90/L), so I need someone who can program these kind of chips.

Any help and/or suggestions much appreciated.

Solved!

With the great help of @superduper, he provided and burned the eproms.
Everything works great!
