Came across this excellent set of instructions that walked me through the process:
Download the patched firmware file & unzip it.
Prepare a bootable floppy disk using the XP format disk function, selecting “Create an MS-DOS startup disk” option. Delete all files from the floppy except IO.SYS, MSDOS.SYS and COMMAND.COM (this leaves a minimal boot floppy ideal for flashing). Use a good quality floppy.
Copy the flash utility (DWL2.EXE) and firmware file (XXX.BIN) to the floppy and check it using Properties -> Tools -> Error checking.
Using Nero Infotool, establish whether your DVD drive is set up as Primary Master, Primary Slave, Secondary Master or Secondary Slave on the IDE buses.
Using the floppy reboot your computer to DOS (you may have to set your BIOS to boot from floppy if it doesn’t do this automatically).
At the DOS prompt enter: DWL2 N XXXX.BIN â€” [key Return]
Except that for “N” you substitute a number from 0 to 3 according to the IDE setting of your drive (see Step 4) as follows:
0: PRIMARY MASTER
1: PRIMARY SLAVE
2: SECONDARY MASTER
3: SECONDARY SLAVE
And XXXX.BIN should be the firmware version number.
Don’t interfere with the computer while the flash is proceeding.
- After flashing reboot and check whether the drive has been updated to the recent firmware version.
Hope this helps the next person with this issue. Good luck, and thanks again!
