Important Notes:
- Perform this upgrade at your own risk, changing anything to the mainboard will for sure void your guarantee!
- There were some problems with the "C" revision but they are solved when using firmware 1.0f or older.
- Add a cooler which cools down the writer to avoid write errors due to overheating.
How-to:
- Leave the writer-tray open and turn off the computer.
- Open the bottom-cover of the writer (4 little screws).
- Disconnect all wires from the mainboard.
- Take out the mainboard and turn it like the picture above.
- Check which revision the mainboard is (the letter A, B or C is printed inside a square)
This fix will work with revision B and C.

The Q/D printed on the mainboard stand for quatro/double
- Cut the R621 resistor (with a soldering iron or with a pliers)
- take all the parts together

Upgrade FAQ:
- I don't trust you is that really possibly?
yes, it is.
- I want to convert a CD-Writer XY with brand Z, is that possible?
no, it is only possible with the two Yamaha-recorders and of course the Traxdata-writers, which are the same.
- How many Yamaha CRW 2260 you have tuned?
not one (one writer is enough).
- How many writers were tuned with success?
I know about 50.
- How many writers were tuned without success?
5-10, but you can use it as 4260 if you use an older firmware.
- My Yamaha-recorder has read- or write errors, why?
You have no additional cooler over your writer and so it has a heat error.
- Does the upgrade work with any revision?
Yes.
- Does a upgraded Yamaha CRW 2260 work correct with 4 times speed?
Yes.
- Some upgraded writer have only 1 Mb cache, are buffer-underruns possible?
No, most CD writes have 1 Mb which is sufficient.
