This happened to me in both situations:
- Bad RAM of course
- Using unofficial processors

Good luck. This is a bad one.

And may I join the club ?
Someone here happens to have an ASUS TX97-XV motherboard (updated to version 0112-1) ?

@Frasco I've found this : http://www.elhvb.com/mobokive/archive/Asus/so … 30tx/index.html
The -xv folder doesn't contain any bioses, but the -x does have many of them. If you're lucky, they will work just fine ^^

@jade_angel I'm not sure if there's anything interesting for you there but I've found this : http://www.elhvb.com/mobokive/archive/Pine/Di … ries/index.html

I cringe when I have to improvise something in my computers 🤣

Looks promise and I can try, now that I have an USB programmer.

It might be bad RAM - I've tried 8 different sticks, both FPM and EDO, but I haven't tested all the permutations exhaustively. Of course, right now, I can't...

As for the CPU, I'm using an AMD 5x86/133, which seems to be working fine, as far as that goes.

That's a better manual copy than the one I have, but, alas, no ROM.

I think it's just about possible that maybe the Biostar BIOS would have worked but my EEPROM is too small, or the flash process went awry, so I suppose I'll try reflashing the chip offline and see if it works.

Failing that, maybe I'll have to dig up another board like this, and I'll make sure to dump a copy of the BIOS and put it somewhere interesting.
