Hello my friends!
I received my "for parts"  TDS 7104 item (many brokens parts, damaged MB, damaged (craked) NLX raiser, missing capacitors, BAD BIOS, BAD Acquisition and control boards FLASHs, missing HDD OS..., and even make it boot's for a several time..(there's some problems with SPC procedure.. but not right now..) NOW, After attempt to add some memory (+256Mb DIMM), and after several BIOS resettings.
I can't enter to the BIOS config!!! Even just reflash it from emergency FDD 1'44.
Who can help me with the CMOS corrupt utility??
On the Tek forum, i'll cant reach it.

I had this problem a few months ago when my cmos battery died.
It kept me from getting into BIOS and also shutdown the 7104 screen.

I needed to access the VGA connector in back with separate monitor.
You need to install KILLCMOS on floppy start-up disk.
Boot from the floppy and run program.



Takes about 20 seconds.
Took 4 hours to find all equipment to put program on disk :-(

The last thing I can think of to get past my "Unsupported Hardware Detected" firmware loading error is to beg/cheat/borrow for a ghosted image - Is anyone capable and willing to help me with that??
SF810 Motherboard, Win2k or WinXP

Mega thank you in advance!

I have SU810 not SF, but it could still work since it is almost the same board. It is about 2GB in size, an image clone of the 24GB drive.
I will upload it somewhere, just tell me if you wish to try it.
You can delete the serial number files when you clone it.
If you clone it to a larger drive you can resize partition later.

Bingo! now i corrupt my flash and re-install .gho image from xDevs.
to my 440zx motherboard and it works!
Scope shows 4 lines for 4 channels, each channels triggered, and shows adequate (and same) info, from internal calib.generator, and from my arbstudio gen. lasts to 125Mhz..

But trying to load selftest shows me, that all steps is PASS, but Misc (the last) step, has number 511, 2-fail counts errors.

And it fails to pass SPC tests.

My device goes (parts cond), without any HDD and OS. I install and run an (gho) image from another xDevs scope.
And in properties, it shows not mine(back panel), serial and option numbers. Thats because it was reflashing it corrupted configs, and calibratings binaries from the image file from vxBoot (from xDevs)??

Or there is a hardware problem (broken equip IC) ??

And another bug- that, when i try to reinstall the newest scope app version 2.5.3.2008, its hangs application, on tektronix logo from start. It there is any tricks??


and when i try to put 512Mb CF card to PCMCIA slot, it slows  the scopes data displays and not appear as disk drive or something.. BUT the "-" on "8"indicator segment, cause blinks an another way periods.
Does the win98 controls that PCMCIA adapter slots? can i add an 4xUSB2.0 PCMCIA adapter or WI-FI or other??

1000 THANK YOU's to ELEKTROPIONIR - I am absolutely elated, this scope is running!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I restored your disk image to my HDD, and had to reinstall all Tek drivers on first power-up, but when completed I rebooted scope, and it fired right up!!!!!!!

You have provided an end to my 2month obsession - Thank you!!!

what i got:
PCMCIA malfunction cause by interrupts.

It can't pass the SPC, because channels, have some DC offsets by mV, from zero.
I delete cal files (on vxBoot) goes with another scope sys image. But it dont help.

I add my bootlog, and SPC log as a txt.
Its physical malfunction of frontend modules or calibration issule??

FYI: I've posted an NVRAM + PowerPC BIOS dump script for the TDS6000B/7000B series

https://www.eevblog.com/forum/testgear/tektronix-tds6000b7000b-series-nvram-dump-script/

At least one person in this thread had a corrupt BIOS and corrupt NVRAMs are only a matter of time.

Hello again, all of my troubles caused by incorrect input module identification. After reinstalling the new firmware from TEK site.
SPC have "pass" stratus. Thanks for everyone!!!
If you need to PCMCIA works- Disable LAN on BIOS...

Hi folks,

My TDS7404 died after working great a few months ago. After having it unplugged for a few months, I went to turn it on and found that the x86 side of the machine appears to have a dead graphics adapter. I can't get into the BIOS setup and no amount of CMOS clearing will bring things back. It does appear to be functional enough to run MS-DOS headless, however, which I can verify by typing commands that make things beep (there's no serial console on the motherboard is there?). You can read a bit more in another thread [1].

I haven't been able to find any evidence of anyone bringing their scope back from this symptom, so my question here is: given that the PPC board seems healthy (boots up to "L" on the 8-segment display) and the power supply voltages check out according to the Service Manual, it seems like I should be able to swap out the BL440ZX with a Windows 7 upgrade kit from eBay [2], which includes a SF/SU810 motherboard and hopefully things should spring back to life (also I'll get a much faster (in terms of usability) scope out of it!), since the bad BIOS/Video Adapter lives on the x86 motherboard.

Am I correct in my assumptions? Is there anything else I should try?

This will get you up and running with the video set to PCI instead of AGP as it should be, even if the on-board graphics are bad. You will need to change the battery on the CPU board as it is likely dead.
It is a DOS boot floppy with a utility to restore the correct CMOS contents which I just made from a TDS7104 with the BL440ZX MB. When you hear three beeps, press F10 to continue booting. When the floppy access light goes out, the CMOS should be restored. Then press CTRL ALT DEL to warm boot the MB. You should then have the LCD display back.

Wow, Jwalling, thank you! That worked and I'm back in action! Not sure what I can do to repay you, but you have my extreme gratitude 🙏

This makes me wonder if the AGP graphics were always dead (at least since I got the unit) and I never noticed because the BIOS was successfully switching off of them to the PCI graphics... until the CMOS battery died. I was a bit puzzled at how sitting quietly, unplugged on a shelf could be so catastrophic for the motherboard and perhaps it wasn't after all.

Also as an FYI for other folks, I successfully used WinImage (the trial) on Windows 10 to write Jwalling's boot disk to a floppy with a USB drive. There was some amount of unplugging and re-plugging in the USB floppy drive to clear contention on it so that WinImage would work properly but it eventually worked.

Now to put humpty dumpty back together again!

hi everyone, really glad to learn from this thread. recently i got a tds7104,boot stop at the scope start screen,I use vxboot to reset and now it boots ok.
but self test ,it reports 521 factory cal integrity ,factory cal data error. I read the boot log,it seems that it can't open some cal file in C:\vxboot\calcon. And i checked in C:\vxboot\calcon, there do missed cal file named 1 to 8 and 15,could this be the cause of error 521? Can anybody share the files ?  Or any other suggestion.

I also find to extract the firmeware 2.5.5, you can see the performance verification installation file,which can be installed and run performence test or adjustment automatically if you have a fluke 9500 with four probes.

hi everyone, really glad to learn from this thread. recently i got a tds7104,boot stop at the scope start screen,I use vxboot to reset and now it boots ok.
but self test ,it reports 521 factory cal integrity ,factory cal data error. I read the boot log,it seems that it can't open some cal file in C:\vxboot\calcon. And i checked in C:\vxboot\calcon, there do missed cal file named 1 to 8 and 15,could this be the cause of error 521? Can anybody share the files ?  Or any other suggestion.


Error 521 is the EEPROM on the acquisition board has been corrupted. It's reference designation is U1052.
Here is a known good U1052 binary from a TDS7104. Obviously it won't have the correct constants for your scope, but it will get rid of the error.
Otherwise you'll need to have a proper calibration with adjustments done.

It’s really great of you! Maybe I can compare your file with mine to see what’s the difference except calconstans ,I wonder how could this happen unless someone had  done adjustment not completely.

Does anyone know if there is a way to trash the contents on the Dallas DS1245 chip on the PPC board?
This one has a PDIP, and I'd rather not remove the chip if it can be done from the console port.
I'm replacing this board in a TDS7104 and I need to get rid of the serial # and key.

Hi All,

I have a TDS7104 that I just rebuilt the disk on.  Everything seems to work fine except I can't do a successful SPC.  I get a fail message on the display.  I have attached a terminal to the PPC console port.  I get slightly different errors each time I run SPC, but all look bad.

I have tried calConStatus = cc_init(1), which seems to execute okay.

I have checked the power supply voltages, and all are good.

So, is my acquisition board toast?

Thanks much

It’s hard to find a new x24165 now,I used a AT24C16B instead, I will try this in a few days.Thanks.

Maybe AT24C16B is not a right choose,I will try to find a right chip again.

Thanks,the error 521 disappeared now,I have made some simple test and the test results seems to be acceptable
