Thanks the tip. I was hoping it wouldn't that difficult. Darn.
I will remove the case and see what the indicator says. Will keep you posted.
Happy Holidays!
One thing to try and easy as well - disconnect the CD-ROM data cable. It could cause problems on the ATAPI bus.
Another thing - I don't remember whether DMA should be anabled in the BIOS for IDE devices. If it's set to enabled, try setting it to PIO mode.
What is the serial # of your unit? I may have a Ghost image...
Lastly, if running the scope with all the covers off, make sure you direct a fan over the ACQ board!!!

If I buy a TDS/CSA8000 that won't boot at all, is there any way of getting hold of a replacement disk drive image?
Joined the TDS7000 club! A very kind friend offered up a TDS7104 that has a few issues and is beyond disgusting inside(so much brown dirt not a single part # on a chip is readable). The BNC's on the front are also green in color with corrosion. Supposedly it came from a motherboard manufacturer in Taiwan.
The nvram powercap battery is dead of course but it seems I also need a new nvram so I ordered one tonight:
romPost: PERFORMING NV-MEMORY WALKING-ONE TEST...
Expected Value: 0x00000001
Actuall Value: 0x00000000
Location: 0xFD0E0000
romPost: NV-MEMORY Walking-one test failed.
Oh the joys of windoze 98 and 128 mb of ram - at least that part boots fine. Assuming it all starts working I'll looking mb, HD and OS upgrades.
Yes, it is the snapcap SMD package. I have already ordered it and it has been shipped so I am getting one either way. For other people with the same problem it appears swapping it has fixed the problem. Swapping out some ram at the same time may not hurt though.

I'm beginning to think that Dallas/Maxim had a lot code problem with these. My defective one that failed the walking ones test is marked:
DS1245YP-100
0035GC

Now that I think of it, I also replaced one in the last several years that would draw excess current on the battery when in standby mode. I mentioned it in this thread, I believe. What are the markings on your bad chip, if I may ask?

The LCD screen is also separated from the touch screen panel so I need to reattach them and hopefully get the alignment better. Right now the touch screen is a good 5 mm off in the horizontal direction.

Re alignment: You may already know this, but there should be a touch screen calibration utility on the scope. Usually there's a shortcut on the desktop.

edit - well crap. The scope is working fine but some of the displayed characters are wrong. Such as it displays the symbol for the british pound instead of the ohm symbol or similar. I assume it is a keyboard/character set or region issue. Has anyone else run into this problem?

Copy windows fonts from your old harddrive to the new. There are three specific Tek fonts and even the ones from win98 work fine with XP - at least in mine.
I have the same scope but put in SU810 MB. No problems whatsoever with XP other than the fonts initially.
Thank you. I had same issue, but never bothered to fix it.
Another issue I have, is that scope dont remeber last settings on power reboot. E.g. it boots with default settings always. Anyone had that? Perhaps bad vxWorks config I have?
Felt like playing with some equipment tonight.
On my TDS7104 the 3dB bandwidth looks to be 1.15 GHz. My P6139B (500 MHz rated) probes 3dB point is 700 MHz. The input SWR of the scope channels when set to 50 ohms is 1.2 or less below 1 GHz. I played with the FFT mode of the scope and if I select the right combo of settings it crashes. To show basic carriers up to 2 GHz is works reasonably well though.
I don't think it is really the PC scope app that is crapping out as much as either the powerPC board or acquisition board. It only happens when I am trying to see a low frequency FFT with a low RBW and really start messing with the sample rate and resolution. I was able to get it to crash with the original Win98 install as well. I don't plan to use the scope as a spectrum analyzer anyway, I have better ones in the lab already. The documentation from Tek really talks about how good the spectral analysis is though so I wanted to see what they thought all the hype was about.
