Liteon SHD-16S1S-05 sata PC dvdrom drive, does anyone have it?

[robinsod]

Has anyone got a Samsung SH-D163A? I would be interested to know what the controller, flash and motor controller chips are - I'm wondering if the H943 firmware could be retrofitted. Is anyone else interested? PM me!

Finally got the drive in......voided warrenty quickly! 

Here's the highest res pics that the host would allow.

If you need higher res than this I can provide them.

The fisrt pic is to show location....others are close-ups.

There is a reduction in the board size....and the biggest difference in this model over my ide version of this drive
(SOHD-16P9S) is the main chip has a P instead of an S..... MT1359PE(Parallel) and MT1359SE(Sata) respectively.
Also noted: the SST is the same on both drives.

Wondering what needs to be done now to flash the drive with something like kreons 0.80 or modding a firmware to work with the 360 discs.

Is anyone attempting to do that?

sorry about the wait.

Did you try dumping the Firmware ?

Not yet! Just got it. 

Just have to put it back together and into a box.

I will post back here once done.

to dump firmware, download and try FlashReader-1.0.6 under windows, and XSF-1.53 under dos with a sata-to-ide converter.

Thanks for the link to extract the flash....."FlashReader" works 

Extracted a 256KB size file....saved as ES01.BIN 

Loaded it into another app that was on that same page called xflash_utility....but only info it gave that was not know was the md5 checksum

hope this is what ya wanted to know.....what next?

anything else?

Here's the firmware flash package from the SAMSUNG website:

Off down the shops to see if I can one...... (I'm in Munich)

Got the Samsung SH-D163A, hope to have some time to make some experiment soon

Note that the MT pins related to standard flash connection (near top-right corner) seems unconnected, like the liteon one.
Note also that TS-H943 has pads for an SPI flash too.

I think that my first test will be putting the SH-D163A SPI flash on the TS-H943

hmm very interesting, samsung SH-D163A drive have "SF-HD68V" laser and xbox1 LG drive "SF-HD68".

how about liteon SHD-16S1S drive?? which laser is inside??

I've started to look at disassembled SH-D163 fw, and an SPI port of xtreme seems not so easy.
At first look (and first time for me about 8051 asm code) in SPI fw, there is a bootloader in first 64KB, then in second quarter of fw there is what looks like bank0 in xtreme fw, same initial routines, .... the routines to switch banks (at relative address 0x1800), also a switching to 4th bank is present but, of course, not xreferenced......but the problem is about terth and fourth quarter of fw, they are attached toghether, i can't see any switching routine, seems a 128KB chunk of code, but i've still to look deeply.
Anyway, porting the xtreme fw to SPI flash means a complete readressing of the routines (to fit fw into 192KB), that's why i didn't try to see if SPI works on TS-H943, because it's secondary relevant.

I think that the MT chip first try to see if an SPI flash is connected to A16 and A17, if not it try for a normal flash, but it's only a speculation.
The only stuff i've tried, is to solder an 25P10 (taked from maxtor HD) to SH-D162C and XSF.exe from dos was able to flash it, so the bootloader inside SPI flash (first 64KB chunk) is only something that probably copys the 192KB fw to ram.

Does anyone have taked a look to SPI flash FW? In second quarter there are a lot of jumps to switching routine to finally jump to bank0, 1, and 2 (relative to 192KB fw) using P1 port, but i've not already seen how the code comes back to bank0.
Why P1 is used? maybe there is more ram internally and P1 is used to switch 64KB chunk inside it, instead of using P1 for external flash?

how about liteon SHD-16S1S drive?? which laser is inside??

After closer examination.....the SHD-16S1S has the "SF-HD68V" laser inside.

Will provide pic if necessary, but it's clearly printed on top of laser housing.

I hope this is good news.  =)~

peace

thx for replay zillionare!

- Geremia any new progress??

[Tiros]

Reformatting the SPI rom content, and adding an extra adress line, I got the TS to run the SHD code in parallel mode.
Some patches to the SHD were required to make it boot on the TS in parallel mode.
It acknowleded in windows, responded to INQ, but would not eject or spin. Motor controller incompatibiites I suppose.

I was unable to make the 1359E on the TS emit the SPI clock and control signals, even though place on PCB for SPI rom.
So I made it run parallel. I was wondering if this drive could be used for parts, IE source of 1359E, as its only a $20 drive. Anybody can swap an shd 1359 to the TS main board would be a good test.
