LiteOn DH20A4P/H Fast Burn, Enhanced OverSpeed & Enhanced OHT Patched Firmware
Fast Burn (-FB):
FastBurn uses a higher burn RPM for 8x and 12x burning with both +R and -R media. Now the 20A4x drives can do 12x burning typically in less than 6:30.
Fast Burn Light (-FBL):
Uses a slightly lower RPM than FB, for 8x and 12x burning. This allows media that failed to burn well at 16x a better chance to burn well at 12x, without sacrificing much burn time. A typical burn takes around 6:30 at 12x.
Enhanced OverSpeed (-EOS):
Enhanced OverSpeed allows DVD+R and DVD-R media to be burned at, up to, 20x. Please understand that because this speed is offered, it does not necessarily mean that it will burn successfully at this speed. You will need to experiment to see what the highest successful burn speed for your media is. If you are using applications that don’t allow you to set the burn speed, then I suggest you don’t uses the version with Enhanced OverSpeed, “-eos” in the file name.
Possible burn speeds above branded speed:
16x: 18x - 20x
8x: 12x - 16x
4x: 8x - 12x - 16x
2x: 4x - 8x - 12x - 16x
Enhanced Online HyperTuning (-EOHT):
Uses a more sensitive OHT, which increases in sensitivity towards the end of the burn, to ensure even better burn quality, while fast burning, overclocking or burning media at rated speeds.

Note: Results can still be posted in the normal scans threads but please state that the FastBurn firmware was used.
1/ Use the EEPROM Utility to make a backup of your EEPROM before flashing, just in case.
2/ The Test SmartBurn should be used to enable OverSpeed (Enhanced OverSpeed).
3/ Only 8x or 12x burns are affected by the FastBurn patch. Burning at other speeds is the same as using stock firmware.
4/ Using this firmware will void your warranty. If your drive should fail after flashing to this firmware, do not return it, instead do the right thing and purchase a new drive.

*DUAL: These firmware flashers have two firmwares installed and will automatically detect you firmware type (A/S) and flash the required patched firmware. These packed files are much larger because RAR solid will not work on files larger than 4MB.
- It is understood that two different Laser Diodes exist in the A4 models. Please make sure you backup your original firmware using the Flash Utility, before flashing to this firmware, so it can be restored if your drive’s LD does not match the type set in the current patched firmware.
- The 9P57 packed file contains both the A and the S version. Crossflashed A1 drives should prefer the A version. With A4 drives you will have to experiment. Going by bichi’s experience, +RW seems to be a good test if your drive has the A version LD, as it did not like to burn +RW when using the S version firmware.[/I][/B]
