I got junk DPO7104.
After some simple power board repair (replacement of the exploded capacitor), I found that the HDD did not work, so I installed MSDN's Windows XP on a new HDD.
I collected the driver from the web, but the following one has not been found.

- Touch screen
(probably Semtech UR7HCTS2-USB from USB-PID047A/VID0004)
- ATI graphic driver
(The rumor is Tektronix's custom driver to support drawing waveforms directly into graphic memory. With the generic ATI driver I got a BSOD)

And tried to install the TekScope app, I get an error that it is not an authorized hardware (I have got an acquisition board driver for VM6000, but it may be wrong).

It would be nice to have a recovery image of DPO7104, but can anyone help me?
Or can you provide information about the missing driver?

Can't you just download this software from Tektronics themselves???

The package did not contain the required device drivers.
It looks like a set of TekScope apps and optional analysis software.

You might try the XDEVS site, Tin keeps a lot of info and programs on his website.

zend03122 · « **Reply #4 on:** March 28, 2019, 05:09:22 am »

The amount of information in XDEVS is great.
However, there is still no information such as the device driver of DPO7104 (DPO7000 series).

The data of VM6000 which is a similar product was in XDEVS, but hardware configuration seems to be slightly different and it did not solve.

Thank you for the powerful information.

I checked the thread but I couldn't find any information about the software I was looking for.
(I overlooked the information?)

The DPO7000 series (DPO7104) looks different in hardware from this thread's TDS7000 / CSA7000 and TDS8000B...

My appologies. I misread the type number in your request. You're probably right, th

I guess to a hamer everything looks like a nail

I was refering to post #12 but it probably won't help you...

Contact me offline, I think I can help you, as I have DPO7k files. It's still work-in-progress project, so many files not published yet on site.
I'm also looking for acquisition board to fix my DPO, if you know any source to help?

zend03122 · « **Reply #9 on:** March 28, 2019, 12:35:19 pm »

Thank you very much for your support.

But I'm sorry, I have no idea now about getting an acquisition board...

I'll upload a photo of my DPO7104 for reference.

LateLesley · « **Reply #11 on:** March 29, 2019, 04:00:24 pm »

So after seeing a picture of the chip, I think it might be the mobility radeon 7000.

http://vgamuseum.info/index.php/news/item/114-ati-mobility-radeon-7000

It seems to be the same as the radeon 7000 and radeon VE series of chips.

So you may be able to get the driver here, and just install the driver without the bloatware, by going through device manager in the OS, going through update driver, and manually navigating to the XP32 driver folder and ini file.

zend03122 · « **Reply #12 on:** March 30, 2019, 02:34:10 am »

I tried your driver, but the inf file did not contain my chip id.
I tried other generic drivers from web but I haven't found anything that can be used.
The tektronix forum says "is a special driver" but I do not know if this is true.
https://forum.tek.com/viewtopic.php?f=568&t=133635

I attached a capture of visible PID / VID from Device Manager.

A similar device, Tektronix's VM6000 video driver, could be installed.
However, when the display's LCD is enabled from Display Properties, I got a BSOD.

LateLesley · « **Reply #13 on:** March 30, 2019, 03:21:00 am »

I might be able to edit the inf so it can install the driver. Leave it with me, and I'll post an edited inf for you to try with that driver software.

EDIT : Try dumping this file into the /driver/2KXP_NF folder, and then installing the driver. If it works, it should pop up as a Tektronix DPO7000 Series driver. (I had to zip it to attach it, so unzip it to the folder)

Oh and I haven't tested this, I don't have the hardware, nor windows! I'm on Linux nowadays.

zend03122 · « **Reply #14 on:** March 30, 2019, 05:58:50 am »

I have to say a big thank you.

The inf file you modified could not be installed as "Tektronix DPO7000 Series".
However, I understood the intention and installed the driver of "RADON 7000 Series" and it was displayed on the LCD panel of the main unit without any problem.

I got closer to the completion of my work.

But there are still some problems.

When TekScope.exe starts up, it freezes on the splash screen and the system (OS) restarts.

The driver is "ATI WDM Rage Theater Video" under RADEON 7000 is Code 10 error.
I will try another version of the RADEON driver.

Another is the intel 82551QM (Network Controller) on the PPC board, and its driver is also Code 10. I will look for this driver from web. (I do not know what to do.)

EDIT: intel 82550M -> intel 82551QM

LateLesley · « **Reply #15 on:** March 30, 2019, 06:13:45 am »

ok! we're closer! We know the GPU. I have a feeling that Tektronix got a cut down version of the chip, so it's probably got parts missing that would be in the consumer graphics cards. My other concern is that it probably doesn't have the same amount of video memory, and if that is set wrong, it might cause issues. Is there any clues in the schematics to how much video ram it may have? The driver is set for 256MB, but I can change that. And I can probably turn off/disable the rage theater stuff too.

If the network driver needs modding too, I can have a bash at it, but i'll need the PID/VID

zend03122 · « **Reply #16 on:** March 30, 2019, 06:45:39 am »

I'm surprised at your knowledge.

The RADEON chip on the PPC board is in a multichip package, with a GPU and memory implemented.
The memory can be read as Samsung "K4D263238G-GC33".
According to this data sheet, it is 128 MBit DDR-SDRAM.
https://pdf1.alldatasheet.com/datasheet-pdf/view/92863/SAMSUNG/K4D263238G-GC33.html

Is this a video RAM?
Your prediction is correct! !

ADD:
The network chip was VEN: 8086 / DEV: 1229.
I do not know what it is used for. (TekLink ??)

zend03122 · « **Reply #17 on:** March 30, 2019, 08:20:05 am »

hmmm,

I tried to set the "MaximumDeviceMemoryConfiguration" entry of ATI's inf file etc,
but the video memory seems to be recognized only as 16MB ...

16 MB (Mega Bytes) are 128 Mbit (Mega bits). 8x16=128 ...

LateLesley · « **Reply #19 on:** March 30, 2019, 10:50:03 am »

OK my bad, the driver might be referencing the megabits, not megabytes. the PC version did come with 32MB, so it does kinda make sense that this one came with 16MB, if it's a cut down version. It also makes sense that the rage theater wouldn''t work, as they''d probably cut out the video codec engine ( for movies, DVD n stuff, not the screen display ). And that samsung chip will be the video ram, it's GDDR. there may be another one hiding on the underside? It might not be though, the 16MB ties up with that one chip, as paschulke2 pointed out.

I think a bit more editing of the inf could crack this.

So, near the bottom of the inf,change this point to 128. :-

[ati2mtag_RV100.GeneralConfigData]
MaximumDeviceMemoryConfiguration=256 ← change that to 128

MaximumDeviceMemoryConfiguration=128

Halfway down the inf, in the [ati2mtag_SoftwareDeviceSettings] section, change this line :-

HKR,, DisableOvlTheaterMode,%REG_DWORD%,0 ← change this end 0 to 1.

HKR,, DisableOvlTheaterMode,%REG_DWORD%,1

Save the inf back in the 2KXP_inf driver folder, uninstall the video driver (tick the delete files option), then reinstall this modded one. Hopefully it'll go in knowing only 16MB is available, and not install the Rage Theater stuff.

I am at the edges of my ( PC ) knowledge here, but I have used these tricks to hack drivers into OS which wouldn't take them. It's fun when it works.

You will have to make sure you completely uninstall the first driver attempt, including files, and reboot, before re-installing this modded one.

I am assuming this is just like running windows on a PC, i'm not sure of what limitations you have.

good luck!!

EDIT : For the network driver, have you tried this one ?

https://downloadcenter.intel.com/download/18717?_ga=2.15617014.1122367556.1553944212-535618971.1553944109

If it doesn't work, i'll have to see the hardware id page in the pro/100 m driver, it seems there are many variants of the DEV:1229, so I may have to see the &subsys and &rev parts, the driver has a LOT of exclusions, which I may have to override.

2ND EDIT - scrub that, I just realised that you mentioned the chip is the 82551QM. It seems it may be an embedded network adapter. Try this driver.

You are absolutely right!!
What was I thinking...?

zend03122 · « **Reply #21 on:** March 30, 2019, 12:43:21 pm »

LateLesley,
Thank you for your kind support! !

Now, during the experiment with the ATI driver, Windows did not start up even in safe mode.
(Maybe I made a mistake)

Because OS recovery takes time, please give some time...

The NetworkInterface driver has tried it, but did not improve it.
I will try again after OS recovery! !

LateLesley · « **Reply #22 on:** March 30, 2019, 03:01:48 pm »

it's possible the modded driver took out the OS, with the memory change. Video drivers in XP, Vista, and Win 7 are one of the few drivers that will outright halt and bluescreen a system. You can sometimes recover if you use "Enable VGA Mode" which will use Microsoft's basic VGA driver, instead of the installed one.

Anyway, once you are back up and running, can you have a look at the &subsys of the network adapter? We might them be able to properly identify it.

zend03122 · « **Reply #23 on:** March 30, 2019, 03:38:57 pm »

Although the graphic is still unstable, I will attach the information of the network adapter for the time being.

LateLesley · « **Reply #24 on:** March 30, 2019, 05:40:01 pm »

OK, you can maybe try this one for the networking. It's a Dell network driver, but it seems to have to code for your chip in it. It seems they used a mobile networking chip, probably aiming for low power as opposed to performance, which would be the best design choice in equipment like this.

As for the display woes, you could maybe try the Display driver uninstaller, all the messing about might have left remnants of other drivers in, which could be upsetting things. you can use this to clean out all drivers, reboot, and do a clean install of a driver.
