apologies that I have no time at the moment to read the whole thread and see what is answered and what is not, but I did a fast search for "IML" in the thread and I don't see it mentioned anywhere. So, IML is "Initial Microcode Load", such machine you cannot go over 3.94GB, no matter what you do, …

@S95Sedan I believe you misunderstood me about the "pin-assignment", I meant not in hardware, but in software, i.e. in 8051-ROM, you can have the same ROM version but depending on the PCB layout customize the ROM different pins of the uC to do different job.

If you have information about some other method, it is very interesting. after over 10 years ago, I did not find anything, but I tried to remember and here it is what I remember: * it was PCIe controller with build-in 8051 controller and ROM that processes HDA commands (that's Intel High-Def Audio …

it needs to be proven. One way to prove - is to write software dumper (if it's possible), and then compare dumps from different cards. I presume hardware dump is very complicated to be made - I don't know how those dumps here were made, but in the past I found picture(s) of the setup used by @ …

it does give an NMI error could it be some different pin-assignment of the Micro-controller between different card models - I mean for example "V4.13" is it exactly the same code on every board with such DSP version or could it be they are slightly different in terms of Micro-controller pin- …

'51 chips with 4k rom cannot work with 4.xx fw. You need '52. I suspect what even modern variants of '52 can be used. xxx51 is an 8051 chip, used for dsp 2.xx and 3.xx (smaller in size, 4kb instead of 8kb) xxx52 is 8052, which is what the 4.xx version uses. Thank you both for giving those …

Helps to have a microscope though no microscope here, so I guess removing/cutting the bottom is still the poor man's way to do it. Creative used a couple vendors themselves, intel, signetics, mhs. I see, I am asking for Signetics, not so much because the original Creative chip on my AWE32 board is …

the bottom, its there for a reason. I agree, it's needed to lift the chip to the correct level - after I cut it and solder the socket, i put it back - it stays between the PCB and the chip - that works for me. However, I will try your advice to use curved tip as well. BTW, I see the original …

After prepping the PLCCs, where would it go on the AWE32 for example? I presume the DSP chip is on different location on the PCB depending on the exact AWE32 model and thus I cannot speak for all models, but on mine CT2760 it's the following chip - CT1741 - it's also the only PLCC-44 packaged chip …

What is the socket that is needed? PLCC-44 for surface mount, i.e. SMD type and not with pins underneath. Also, the bottom plastic needs to be easy to remove (otherwise you cannot solder it by hand), which is kind of hard to judge by the picture of the socket itself - I am making this note, because …

have you searched drivers/media/usb/tm6000/tm6000-cards.c ? There are lots of entries, you might find some original source info..... the device is there, but as I said it's not working. so, as I see it, that entry there is like "placeholder" for future fixing/debugging and adding of a real support. …

@Horun: you're both correct and not!

According the info on LinuxTV, what you have linked to is the original source code for the drivers. https://www.linuxtv.org/wiki/index.php/Trident_TM6000 yes, exactly, but unfortunatelly all those links are dead - that's my problem.

@ConteZero : maybe, I am not getting entirely what you're saying, but I think you're mistaking Envy24 (with chip marking "1712") and later Envy chips (like Envy24HT-S for which is the initial question). they technically are from the same Envy-family, but later ones are marked as VT172x (for example …

looks exactly as "iBASE MB800H", but the board on the picture from the 1st post says "PT-MB8000H" - I've never seen iBASE board with prefix "PT-" in its model. So, I think it's other manufacturer (or maybe just another brand and still iBASE made it) using the same or very similar design as "iBASE …

If you do look into SiS chipset specific slowdown tooling… I will most certainly do, I've already took out 2 of my Futro S400 from storage, but I don't know where I put the power supplies, which is what is stopping me at the moment. However, while I am looking for the power adapters, in case …

yeah, Futro S400 is quite nice, because SiS chipset has DDMA support: https://www.vogons.org/viewtopic.php?t=70375 and so that's what the patched Yamaha driver is using - the compatibility should be very high. I wish we had tool like this: https://www.vogons.org/viewtopic.php?t=87013 but for SiS …
