DosFlash and DosFlash32 V1.5 Beta
-----------------------------------
- now supports serial flash chip MT1309E with mediatek status 0x72 like the SH-D163B, SH-D162D,
  Asus DVD-E616A3, Asus DVD-E818A3, Sony Optiarc DDU1671S
- SST25LF020A and SST25LF040A chip support added
- DosFlash32.exe ported from MFC to plain Windows API, exe size is now 22 KB
- new port i/o driver, because giveio.sys can't be compiled for 64 Bit Windows
- DosFlash16 changed slighly in manual mode, one parameter is added to support SST25LF020A and
  SST25LF040A
- two new methods of BenQ soft unlock are now possible on all motherboards with only one power
  supply unit
- 1st method is powered by Geremia's unlock core, thanks for the complete idea, concept and
  source to Geremia
- 2nd method is the Magic28 key send, this only works on BenQ VAD6038 firmware, thanks to
  c4eva and podger for the initial idea
- the two unlock methods are send one after the other if the drive is a possible unlock
  candidate, first the Magic28 command, then Geremia's unlock commands and after that the
  already known power brute unlock is send to the drive, you can cancel any of these methods
  before they are send to the target, this only applies to BenQ drives with a locked flash
- DosFlash.typ updated
- other minor improvements
- DosFlash32 is now ready for
  - Windows 2000
  - Windows XP 32 Bit
  - Windows XP 64 Bit
  - Windows Server 2003 32 Bit
  - Windows Server 2003 64 Bit
  - Windows Vista 32 Bit
  - Windows Vista 64 Bit
- Warning: Drivers for Windows Vista 64 Bit need to be signed, because we can't afford the
  money to let portio64.sys sign you need to do the following:
  1) Log on as Administrator
  2) Enter the following command in a Dos-Box:
     "bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS"
     (we made sure there are no typos in the line above)
  3) Press enter and reboot your PC
  4) Press F8 key upon initial system boot up
  5) Choose to disable forced driver signing enforcement for that boot session


The following only applies to drives with a locked BenQ flash.


Geremia's BenQ unlock with DosFlash16 / DosFlash32 on any motherboard with the PC's psu
-----------------------------------------------------------------------------------------
- disable CD-ROM boot option in BIOS
- connect BenQ to your PC's power supply unit and SATA port
- power up PC, wait until bootup is finished
- eject tray of the BenQ and shutdown PC completely
- push the BenQ tray half in
- power up PC and boot into DOS for DosFlash16 or Windows for DosFlash32
- run DosFlash16 in auto mode for DOS or DosFlash32 for Windows
- if you read the following:
  MTK Vendor Intro failed on port 0xXXXX. Because there seems
  to be a BenQ drive connected you should try Geremia's
  unlock method.
  - Eject drive tray
  - Power off drive
  - Push drive tray in until it is half open
  - Power on drive
  - Press "Yes" if you are ready
    Are you ready (Y/N)?
- simply press 'Yes' without doing anything of the above, because we
  already did that before starting DosFlash16 / DosFlash32
- the BenQ flash should now be identified
- go on like usual


Geremia's BenQ unlock with DosFlash16 / DosFlash32 on any motherboard with 2nd psu
------------------------------------------------------------------------------------
- connect a separate power supply unit to the BenQ, don't turn it on yet
- power up PC and boot into DOS
- run DosFlash16 in auto mode for DOS or DosFlash32 for Windows
- if you read the following:
  MTK Vendor Intro failed on port 0xXXXX. Because there seems
  to be a BenQ drive connected you should try Geremia's
  unlock method.
  - Eject drive tray
  - Power off drive
  - Push drive tray in until it is half open
  - Power on drive
  - Press "Yes" if you are ready
    Are you ready (Y/N)?
- do the above and press 'Yes'
- the BenQ flash should now be identified
- go on like usual


Magic28 BenQ unlock with DosFlash16 / DosFlash32 on any motherboard
---------------------------------------------------------------------
- connect BenQ to your PC's power supply unit and SATA port
- power up PC and boot into DOS for DosFlash16 or Windows for DosFlash32
- run DosFlash16 in auto mode for DOS or DosFlash32 for Windows
- if you read the following:
  MTK Vendor Intro failed on port 0xXXXX. Because there seems
  to be a BenQ VAD6038 drive connected you should try the
  Magic28 unlock method.
  Do you want to send the Magic28 command?
- press 'Yes'
- the BenQ flash should now be identified
- go on like usual

DosFlash and DosFlash32 V1.6 Beta
-----------------------------------
- fixed power brute unlock bug for VIA cards, this can stop your VIA from working
  with the power brute unlocking in Version 1.5
- for DosFlash16 in auto mode on DOS my VIA card works best if I do a cold boot
  and power up the drive short before or with the PC
- for DosFlash32 on Windows my VIA card works best if I power up the drive short
  before starting DosFlash32
- for me the VIA works with internal and external connectors on DOS and Windows

Sorry for the trouble!

Excellent release. I'm hoping this will help me flash these BenQ's with the different FW that can't be erased or written to with DosFlash 1.3.

Can someone point me in the direction of more detailed instructions on how exactly to use this new DosFlash. I have been using the "benbatch" files very successfully up until now. But it seems this new DosFlash requires a few different parameters, and the read me is not that explicit on how to use it.

Thanks for your perfect software.
I have a little problem and it's that when I start DosFlash32 in windows XP and connect my benq drive, windows starts to act a little bit weird. I mean it keeps freezing for some seconds and then again working and then freezing and working and this keeps repeating until I restart my PC. By freezing for some seconds I mean everything freezes even my mouse pointer. I also can't Enable my IDE DVD-ROMs and writers after closing DosFlash32 and I must restart my PC.
I have VIA6421 sata card.
What can cause this problem?

Thanks, but I think it's far from being perfect at all. I am only a hobby coder with too much free time on holidays.

I had this problem sometimes with the BenQ and the new LiteOn at testing. After I eject tray and loaded it again the system seems to return to normal. I don't know really what this is, but maybe try ejecting tray and report back if this works. Maybe it is related to the changed inquiry command or some other little minor change in fw for these drives. I never had these issues with normal PC-DVD-ROMs in my testing. But maybe some firmware guru can help out and explain what could potentially cause the hang? Would also be interesting if we are the only two that had this issue for the BenQ.

Can anyone comfirm that this drive can work with the "normal BENQ" VAD6038-64930C firmware?

Indeed.. the drive accepts aqnd works with the VAD6038-64930C spoofed as Lite-on in my xbox..

Pretty cool with a black DVDtray instead of grey 

TSX1: Your right this is a "perfect software".... All my issues went away with the lastest version... I have seen very similar behavior...

I have a Via card, CT2 etc similar to you...

I found it would lock up with Mode-b switch asserted on the CT2... On mine the leds were a blue circle, drive would be completely dead and system would freeze, then come back etc... I changed it to red X and worked perfectly.......
But I really doubt if Dosflash has anyhting to do with it..

Doesn't this already work with V1.6? Or is this a different VIA card? Maybe send me some details as the vendor ID, subsystem ID and the supported number of IDE and SATA ports.
