Oh yes I certainly do.
It's a PC first running scope SW. Any scope running Windows should be though of like this.

Get the PC bit right and the rest will fall into line.

Yes and no. Getting the PC part up and running to the point where it boots Windows properly is step one. Step two is to get the equipment specific drivers installed. If you have an original disk then it should be possible to get the right inf file and .sys files from it. If you are lucky these are in a seperate directory together with the software. If you are unlucky you have to take these from the inf and system32 directories under the WIndows installation directory. Not undoable but it takes some skills on dealing with how Windows is structured.

And even then there may be less obvious parts of the software. The route I have taken with my 54835A is to make a backup of the original disk and use the official software updates to get to the latest software version. I didn't re-install Windows 98.

I've noticed that if you just keep cancelling all the "found Hardware " wizards you can sail almost to the end of install, unfortunately at the ens the same BSOD awaits, so who knows you may have to install one of the drivers along the way, will keep playing.

Actually, no and no may be closer to the truth.
The way I see it HP/Agilent runs the scope application from a ramdisk, that  is being setup at bottime. They even mention something about it in the instruction manual, to the occasion that you can just turn the power off to the scope without worrying about a normal windows shutdown procedure. Plus that  the windows itself doesn't require normal serial number input , indicates that the windows install was rather highly customized on these scopes, hence no application install files, no drivers, etc.

Yes, there are drivers, but you do not know where they are and how they are called. The system does not know this either and installs standard non-proprietary drivers with a newer date.
You were correctly told - you should not allow Windows to choose drivers.
Windows prefers drivers that are often incompatible with special hardware. The drivers you need, often do not have compatibility data. You must manually point to them. During the installation process, you should not have chosen "automatic installation", but rather specify the location of the necessary ".inf".
Sometimes it is useful to even completely remove the driver from the system, which Windows tries to install automatically so that it does not interfere with the installation of your driver.

I extracted all the drivers from the running 54845B system. Download them from the link and update each of them by force:
https://drive.google.com/file/d/17D6171w5FhPHHetg21qx1XyKgS37PN_P/view?usp=sharing

In addition, you will most likely have to independently find on the Internet and install the drivers necessary for your new set of i810 motherboard chipsets (which are not in my set).


Try this:
Choose the PCI video adapter as the first one in the BIOS and it is advisable to disable the video processor integrated on the motherboard.
After installing the disk image do not agree to auto-install drivers.
First, download and install the drivers for your motherboard manufacturer for y set i810 chipsets.
Then manually install the "Chips & Technologies 65550 PCI" video adapter driver by specifying the path to the .inf in the appropriate folder in my set.
After that, manually install the latest driver from my folder for the "548XX Scope Interface".
Reboot after each step.

why not install Windows XP (32) on that scope... and then copy over all software needed and if i am right there is a Windows xp version of this scope so drivers and scope software should run...
or is this cutting the edges too much?  i don t know what motherboard you have exactly. or did i miss that way back ;-)

keep on following you...
