Samsung SH-D163B Low noise RPC1 Firmware

Scan-C · 07-12-2008

Hi!

Here's a speedreduced RPC1 firmware for the Samsung SH-D163B. It's patched to run at the following speeds:

DVD-Rom/-+R/RW/DL 4x
CD-Rom/R/RW 8x

This firmware is based on the SB02 firmware from October 08.

Just to be safe: Use at your own risk!

Greets,

Hi!
I know you explicitly wrote a speed reduced firmware. However, I'm looking for a RPC-1 only patch. The only ones I can find are based on an old firmware version. So i was wondering, if you could help me in identifying the RPC specific part in the firmware. Then I'd be able to make a RPC-1 only patched firmware.

What I did so far was to compare the original Samsung firmware with your patched version. Here are my guesses what the changes actually do.

Code:

Address:      Orig    Patched Guess
0x00023672    0x08    0x04    speed
0x00027566    0x20    0x08    speed
0x0002756A    0x30    0x08    speed
0x0002758C    0x06    0x04    speed
0x00027590    0x10    0x04    speed
0x000275A9    0x06    0x04    speed
0x000275AD    0x08    0x04    speed
0x000275C6    0x06    0x04    speed
0x000275CA    0x08    0x04    speed
0x000275D1    0x06    0x04    speed
0x000275DC    0x05    0x04    speed
0x000275F9    0x08    0x04    speed
0x00027612    0x06    0x04    speed
0x00027616    0x08    0x04    speed

0x000320AF    0x60    0x80    rpc
0x00032AB7    0x70    0x80    rpc
0x00034FC1    0xBF    0x00    rpc
0x00034FC2    0x06    0x80    rpc

Please let me know if I'm wrong, or if I have to change additional elements (i.e in order to satisfy checksumming, etc)

Thanks in advance!

You guessed right

The last four patches are for RPC-1. No need to correct any checksums on this drive.

DonSam82 · 22-02-2009

Thanks a lot for your immediate answer! I gave it a try and changed the values which were identified as RPC related. So far everything seems to work fine.

Do you have any additional information related to the speed parameters? I'd like to know what particular function the offsets have.

Scan-C · 23-02-2009

I'd have to look over the firmware again but I remember that you only need to change 4 values to slow down the drive for CD and DVD. Just patched everything to be sure the drive doesn't spin up when weird media is used

Basically there's a media code 4?-Bytes before the actual speedpatch. Some parts are equal for all DVD and CD media the other refer to the exact type.
I'll write down a list which offset controls the speed for the exact media type when I find the time.

Does this firmware works on The Samsung SH-D162D Drive? since the only difference seams to be The IDE/SATA Interface.

And i was looking for The Low noise SB02 firmware for The Samsung SH-D162D Drive

No. You might render your drive useless forever.

macnavarra · 06-03-2009

errr Scanc-C low Noise and Mr. Shine RPC1 so Thanks a lot Scan-C for the SB00 low noise Patched firmware if u got some spare time maybe u can take a look on the SB02 version for the SH-D162D and patch it to low noise

Scan-C · 08-03-2009

I'll do that sometime next week. Should be a pretty easy patch but I have to take my HTPC apart to get a drive for testing

I would patch my D163C drive. Could you show me any hints to do so?
