I have the same logic analyzer and I used this command yesterday. :) It haven't helped me, but first things first.

I bought the device on ebay for a rather low price. The seller assured that the device is in full working order, but after recieving and launching I faced a loading error. It printed "Operating system not found".
Further research revialed one more issue, the BIOS settings resets after each reboot. Certainly, I had changed the battery. The fault was a soldering defect in battery socket, after fixing it the setting got saved. Another issue was missing operating system, I could install no one of them. I thought it could be a broken HDD, since it was detected and offered to install OS, but OS didn't boot from it. Tying another HDD didn't solve the issue. It was a bad soldering again, this time in the HDD connector. So I faced two bad soldering in one device, which is really weird, particularly in a device from such a vendor.
However, I fixed all the issues preventing an OS launch, and got the device to work. The analyzer part works fine, I tried a couple of software versions, windows XP and 2000, even the network controll of the the device.

At this stage, I noticed that CDROM and PCMCIA don't work in Windows XP. CDROM doen't even open after Windows loading, but works in the safe mode. PCMCIA cards aren't seen by the OS and froze up the Windows after plugging or unplugging. In Windows 2000 plug-and-play works fine. This issues remain open.
My next effort was to upgade the hardware. I installed new memory (2x256MB), whereby 512MB memory doesn't work. Also I installed a SSD through IDE-to-mSATA adapter. It had taken some time, because my adapter turned out to be broken and broke the first SSD I installed. Furthermore, I haven't a PC with IDE or mSATA, so I couldn't check adapter and disk separately. Nevertheless, I make it work, and the upgrade really speeded things up.

The next part is the CPU. The standart CPU is SL4ZL - Intel Pentium III 733 MHz Coppermine. Pentium III... I used it in some PCs about 20 years ago, trying to remember... So, it has a few sockets, including FC-PGA1 and FC-PGA2, which are slightly different. And a few cores, including Tualatin and Coppermine. The top Pentium III processor is Intel Tualatin Pentium-IIIs 1.4GHz(512K), which has twice a frequency and a larger cache. It also has a different socket, but the difference is slight, and there is an adapter for it. ( https://www.ebay.com/itm/Intel-Tualatin-Pentium-IIIs-1-4GHz-512K-include-On-chip-Socket-Adapter-/281238323137 ). Another problem is the BIOS. Analyzer's BIOS doesn't support Tualatin, and requires some modifications for working with it. I thought OK, and bought the top Coppermine (1000MHz), which must be faster. It didn't launch. Both the Tualatin an Coppermine CPUs works fine in another motherboard in a casual PC. Further research led me to a screenshot, where the similar device booting with 1000MHz Coppemine ( https://imgur.com/a/ZNVAbjV ). I noticed the different BIOS version on the screen. Mine is 1.00.01 and 1.00.03 on the screenshot. I asked the post author for his BIOS image, but he already sold his devices, he send me two files, but he don't know what versin they are. I also found the 1.00.02 BIOS in the network ( http://profilabs.com.ua/TLA715_DUMP.BIN ) . UNIFLASH successfuly save my BIOS to file. But when I tried to flash the fresh BIOS with UNIFLASH, I got an error. It seems like there are a write protection, and the BIOS can be flashed only with programmer or the original floppy disk (UPGADE7UP Option 41).
To get UPGADE7UP Option 41 will be even too fine. It would be fine if device owners with the 1.00.03 BIOS version post here, we can try to save a BIOS firmware. I will report any of my result.

BIOS upgrade Disk for v1.00.03  from Tektronix is part number 063-3597-02. Don't know about UPGADE7UP and if it included the BIOS upgrade disk.

Do you have it? I couldn't it anywhere.

I inquired about it before and Tektronix gave me the part number. They also charge for the disk. Don't know if it is in a special format as they didn't appear to want to give it out for free. Contact them to find out more.

Here's the content of the 1.02 floppy for those interested with the flash utility.
if anyone can read out a 1.03 bios and upload it to share that would be great

BTW  make the floppy bootable,   write the files to it then reboot from floppy for BIOS update.
that's all the instructions say.

EDIT
Warning:   I did load this bios update which was a 1.02 same as my TLA715,   it read the BIOS.ROM and PLATFORM.BIN files and writes to flash.   no interupting it.
my TLA is bricked.  it will no boot to even show the BIOS information.

proceed with caution if you want to try this.

now to see if I can figure out how to un-brink my TLA
