have found an archive with the rom creator

(for anybody in the attachment)
yesterday creating a rom. first tryed a saved rom from atiflash-4.17 under dos (freedos) with the unflashed card. no errors logged. rom done with lion 10.7.5 on my mac pro 1,1/2,1 (upgraded)
result: black screen, running fans. (power from logicboard 6pin and from optical bay with adaptor molex to 8pin)
today flashed another rom, now created with a rom (yesterday) saved under win with gpu-z with the unflashed card. used rom creator under el capitan, no errors logged.
in both cases no new id and so on. (picture attached) => you can see what i have done for flashing.
what i made wrong ?
have anybody a matching patched rom ? maybe icemac ?
