Need firmware for MSI MS 8348 B (orig. Benq 4816P)

[sost]

I tried to flash my MS 8348 B with firmware found on MSI pages (ATZ Win)
The flash appeared to work perfectly, but on re-boot CDR was dead. Even the bios did not recognise my drive.
I hope that if someone send me firmware in bin file might still be able to fix my drive using dos loader like as mtkflash.
