Итак, что я пробовал:
Во-первых, скачал новый Uniflash v1.37 и nvflash v5.08
Во-вторых, стал пробовать
(Разумеется , всё под чистым DOS’ом)

nvflash -f 1.bin -5 -6
NVIDIA Flash ROM utility
Version 04.46
Chip name=GeForce FX 5200 Ultra, Vendor ID=10DE, Device ID=0321
Opened 1.bin successfully.
Checking for supported EEPROM...
EEPROM man.ID,devcode (20,FF) : Unknown

ERROR: Supported EEPROM not found

Пробовал два варианта прошивок:
Первый – оригинальный 62k (1.bin), второй – добил первую прошивку FF-ками до 64k (3.bin)

Пишет, что поверка не прошла и предлагает попробовать ещё раз

Тут он пишет Error #100 Disk read error
Затем: Unable to read file! (Атрибуты проверены, да и не в них дело)

Видимо, проблема в ROM ID, попробовал восстановить:

Без результата.

Также пробовал Wfflash v5.3 с параметром mn

Load original VGA ROM/Image and save to

Try it again (Y)es or (N)o?

Напомню, что у меня MSI FX5200, которой была залита прошивка от FX 5200 Ultra
