Hello guys :),
that’s my first post here (although I’m a regularly reader) and I hope to get some help from you.Sorry, but this post will get a bit longer just to be as precise as I can.That’s my situation:
I’ve an older DVDRW burner “Optiarc AD-7580S” which is a OEM QSI Drive (Chipset MTK MT1859L).I’ve tried nearly all flash utilities out there to make a firmware dump.The bad part is, there is no flasher that supports this drive except the Windows flash utilities from Optiarc and the QSIFlash utility for DOS.After I examined the QSI utility,it seems that it has an option to make a dump.But this option doesn’t work.I think there is an internal VID/PID check for specific drive models and depending on the drive it decides which options to allow.Maybe I’m wrong,but that’s my first thought.
If you type e.g. “qsiflash.exe /h” or “qsiflash.exe /?” or something similar as usual, it doesn’t output much information about it’s supported command line options.After examination I discovered that it supports the following options to display some help/usage info: “qsiflash.exe /detail” and “qsiflash.exe /usage” (see QSIFLASH.TXT for output).On my drive only the options from the /detail output are supported and the other options do nothing,although they are shown.Now,my questions are:
- How to check if the unsupported options are just disabled or if they are just some left strings that they forgot to remove at compile time?
- What information about the drive would be needed to add support for this drive to binflash? Maybe I can help to get this drive working with binflash (if possible at all).
- Does somebody now a source where to purchase the MTK MT1859L?
I contacted Mediatek but they say that they dont sell this chipset. OK,that’s enough for now. I would have two or three more questions,but this would be beyond the scope of this post.
Thanks in advance…
