Trust me, if it were bad, I'd bash it.

I have compared the firmware fs0b (411s) and the firmware of the 811s - there are only about 34 KB difference and even the comprison of the fs02 to fs0b showed a difference of about 700 KB. So I guess the 811s uses the same chipset and the 411s should work with the 811s firmware.

So we only need the 811 eeprom, if someone has it - please post it or send it to me.

No, I don't have the file yet.

(coolstuff also requested this over CDRLabs PM to me.)

I don't think it will work anyway. 8x writers will become as cheap as 4x writers now when the media for 8x writing are available.

Jeez, here we go again.
Folks, please do not touch your EEPROM. Flashing EEPROM from one drive to another will not result in anything but lousy burn quality, and even dead drives. EEPROM is specific to each drive and is not interchangable.

Yes I would. I'll bash anything that's bad.

Ok I agree : don't mess with your eeprom - when you don't know what you are doing

BUT: After comparing many eeproms I come to the conclusion:

1. every eeprom has 1024 Bytes :o
2. most of the eeprom data is the same on every drive
3. about 130 Bytes are drive (individual) specific
4. at least 3 Bytes dynamicly change from burn to burn or firmware version to version (on the same drive)
5. AND there seem to be 5 magic bytes that are MODEL specific

I don't know the values of these 5 Bytes on a 811s - if we find out - maybe there is a chance to overclock a 411 to 811.

I know I void my warranty - thats my risk.

Are you really serious about "overclocking" 4x DVD writers to 8x DVD writers?

Personally, I don't care much about warranty on my drives - I waste my money anyway just by having them (regardless that I bought them or got them for free.) I just feel it's making a fool of oneself, I mean if it were me.

I have it from a fairly reliable source that overclocking the 411s (or 401s) to the 811s will not result in a working 8x burner, so the 401s/411s is NOT capable of 8x recording.

That might be right - but I want to try it out myself.

:roll: ..for fun an to make my friends look like this -> :o

btw:

Take a hex-editor
Open the original 811s HS06 Firmware from Liteon
Look at address F0066 (BIN) or 93B8A (Flash EXE) ... and you will find a string you wouldn't expect there: "LDW-411"

So what does it mean? The 811 is a 411? At least the 811 uses some or more exactly 97% of the 411s FS0B firmware.

LDW 811S

Postby yazoo on Sun Nov 09, 2003 6:48 pm

Can someone extract the 811S EEPROM through LTNFLASH tool and send it to me? I am willing to overclock my 411S and I would give it a go.

Just look at all the failed drives and requests for EEPROM's since stupid people messed up their drives with it......


Well isn't that a good thing? Shows you how many stupid people are out there pretending to be gurus, until they fucked their drive up and start blaming the drive manufacturer or programmer. You know, they should've put in the readme "Warning: Don't run this program if you're not the programmer. And don't come crying when you fucked up your drive. It's your fault, and your fault only."


Not gonna pickup this drive until Lite-On comes out w/ the 4th firmware update, plus 8x DVD+R are in 4x DVD+R on sale price range.
