Hi all, I’m new to the site and hope that someone could help me with a problem I’m having.
My PC has the Philips DVD8601 drive and recently discovered that rather than just update the firmware I can actually crossflash the hardware to turn it into a Benq drive with more capabilities. I discovered an old post on the site which I quote as follows…
"I have successfully transformed my Philips DVD8601 into a Benq DW1620. Here’s
what I did:
Obtain a copy of B5G9.zip which contains B5G9.exe, a Windows program to update the firmware of the Benq DW1600. This is available here - http://support.benq.com/files/storage/Firmware/DW1600/B5G9.zip
Use a Hex editor on B5G9.exe to change the checksum of B5A9 (the checksum of the original Benq DW1600) to 6D11 (the checksum of the firmware in the Philips 8601). Details of the edit are
Location: Original Value -> New Value
F390: 42 -> 36
F391: 35 -> 44
F392: 41 -> 31
F393: 39 -> 31
Run the edited B5G9.exe. It will apply its firmware modification to the Philips 8601, turning it into a Benq DW1600.
Obtain a copy of 1600-1620_B7K9.exe from the Benq Web site here:
Run this. It will update the Benq DW1600 to a Benq DW1620.
I understand this up to the point of using a Hex Editor program. I’ve downloaded Hex Workshop 4.2 and have just realised I have no idea even where to begin looking or editing the “checksums” listed here.
Could anyone give me some pointers how to use this (or a similar) program to edit the firmware update file?
Any input at all would be greatly appreciated since the Philips DVD8601 is a bit poo by dvd burner standards!
Thanks in advance
