Installing on a Tatung TWN-5213 CU

After booting from that installation, which had loglevel=8, the display ends here.

Converted a photo to text with Tesseract and edited to correct some errors.
May have missed a few.  If you want to see the photo, can post it.

Any insights?

Thanks,                  ... P.

Hello gadget42,

Thanks for replying.

does this help?

Unfortunately hardware details are minimal.  For example, the serial port
has an unusual Hirose connector for which the pinout is not specified.

Might solve the serial port by working with a breakout box.  Also, open
the case and inspect the board.

Thx,                         ... P.

Hi peasthope
I just reread this thread and realized something.

Since you used another machine to install onto the CF card, you
don't need to rerun the install program or use qemu every time
to try different boot codes.

Just plug the CF card into the machine, mount it, and find the
extlinux.conf file, probably under the CFs boot directory.
You can then edit the extlinux.conf file directly.

In reply #7 you stated the  "acpi=off"  boot code removed this error:

Code: [Select]

ACPI BIOS Error (bug): A valid RSDP was not found (20250807tbxfroot-222)I would leave that boot code in there.

Try adding these one at a time:

Code: [Select]

I don't suppose you can access the BIOS on this device.

Haven't found a way in.   No hint on the screen after power up.

Five buttons and a rocker on the bezel.  A procedure with those
might open the BIOS but there are many possible combinations.

@peasthope, the user manual does show advanced boot options/procedures in section 5.3(page-17)

here is a direct link to that page for your convenience:
