***To summarize my quest***

• I have asked you to find an updated BIOS for an ASUS TX97-XV (regular)(not OEM from HP)
  
  You have found it, so I did the BIOS update and this BIN file rendered the poor ASUS useless (first time I do that in my life)
  
  A good thing I always save the OLD BIOS in a file and I have a programmer.
  
  So now I am back to the start position.

ftp://ftp.tekwind.co.jp/pub/asustw/beta/mb/bios/xv5x1121.zip
This is the only link available to download xv5x1121.zip and file is located in Japan - No wonder why this BIOS update is incompatible with my board.

Someone here happens to have an ASUS TX97-XV motherboard (updated to version 0112-1) ?

Lazibayer, don't mind we didn't notice link was from Japan. You just did what I asked you to do. 🤣

What difference does it make if the file is hosted on a server in Japan?

Anyway... I donwloaded the file and extracted the zip. You get 0112XV.001 file which is weird for a BIOS file - header has LH5 in it. So it's compressed. When you uncompress it, you get stn.bin file. Not sure if BIOS flasher does the decoding - something to look into.

Dunno. I think I'm twisted in the sense that i have heard about japanese computers and a hardware called
LAPC-N (LAPC-I X LAPC-N). Otherwise what would explain this incident ?

You get it.

I used PFLASH.EXE as the BIOS flash writer. At some point it showed a big blue message:

DON'T DO IT ! (not with these exact words) and I did it.

What is this stn.bin for ? 😠

No idea, but I managed to get a TX97-XV from a curbside HP a few years ago and that board was waayyy different, layout wise. The TX98 is the narrowest ATX board I've ever seen, the TX97 is a massive behemoth that uses all three rows of mounting screws. It looked identical to the retail model.

The TX97 was faulty so I had to get rid of it. But yeah, same chipset, video, etc. but two cache chips and some huge National Semiconductor chip on it. It may have had a different version of the Mach64, but I don't remember. I'm pretty sure both use the 264-VT judging from the manual. The TX98 uses this bizarre 256x16 45ns EDO VRAM that only one guy on eBay seems to sell.

I have that same board, but it works though, i hate the bios but decent board, any way to change it to Award Modular Bios that is on the retail TX97-XV boards, or could a Award bios chip from a Baby AT or another ATX ASUS 430TX board work on it?

I tried it, it POSTS, but it hangs when attempting to boot. *UPDATE* used a different BIOS IC and it boots, but gets the can't write ESCD error.

Is there a 5v/12v jumper for the Flash chip? Make sure it is set to the correct voltage for what you're using. Or the motherboard could be compatible with one type only.

it's the default flash chip it came with, i just hotflashed it with an ASUS P2B, it's a 2mbit (256k) atmel bios chip. It originally had the HP Phoenix BIOS on it, but i flashed it with an award bios. there's only jumpers for the CMOS reset, and the CPU config, unfortunately.
