boot from a DOS disk, I used a Windows XP MS-DOS startup disk
- at the prompt type:
DosFlash r DFA0 1 a0 1 4 orig.bin 0
- press return
- DosFlash16 will ask you if you wanna resend the mtk vendor intro cmd, press Yes
- after you pressed Yes the drive status is shown on the screen, it's something like 0x7F,
this will change during the next few steps
- turn on the BenQ psu and wait 2 or more seconds, status changes between 0x51 and 0xD1
- turn off the BenQ psu and wait 2 or more seconds, status will stay at 0xD1
- turn on the BenQ psu, you should get a good drive status 0x73 and flashing should start
- this worked only one time after the computer is powered on or resetted for me
- writing and erasing works the same way
- for erasing type:
DosFlash e DFA0 1 a0 1 4 C7 0
(C7 is the sector erase opcode for the BenQ flash, if you need
to erase another drive, lookup the value in the datasheet or DosFlash.typ)
- for writing type:
DosFlash w DFA0 1 a0 1 4 ix14.bin 0
