Maybe a bios problem. Do you have another motherboard with a similar bios socket that you can do a hotflash procedure with?

Oh and that new battery was actually new from the blister package? Because your board still reacts as if the cmos battery is too low.

Thankyou for your reply. Is it true I can put the bios in a NIC with a socket and do it that way?

I recieved an entire pc with an asus TX97-XE and AMDK6-3 400mhz. From what I can see online this cpu was not supported officially however the PC was sold as "ready to go" and working.
I have removed the motherboard from the pc and placed on a bench with a different PSU.
The behaviour is the same with all cards removed. Including ram. I have tried a 120mhz pentium too and the system now waits to be turned on, but will not respond to power or reset buttons afterwards.

When you changed the cpu to 120Mhz did you set the jumpers properly ? 60mhz bus and 2X multiplier AND set the voltage to 3.4v (STD) or 3.5v(VRE).

I did check and double check beforehand!

I have a biostar m5ATA motherboard which also has an award bios. I might attempt a hotflash with that board.

If the chip is the same size and organization it might. I don't have information on that however. The other board methode seems safer generally speaking because you can use the bios flash utility native to that particular bios. Make absolutely sure about the programming voltage used before swapping chips etc.

IMHO, unless the deal was extremely good and worth keeping just for the parts that are working (if any), you should consider returning it . It was, after sold as "ready to go and working" but clearly isn't .

As for the compatibility of the board and CPU, apparently later BIOSes might have supported (patched BIOSes even supported "+" variants) it and the board can apparently be made to provide the 2.4V the CPU requires .

See http://www.lairdslair.com/TX97E.shtml

Oh it is definitely worth keeping.
£49.99
Perfect condition biege atx desktop case(I was considering an evercase and this is less money and includes an entire pc..)
k6-400mhz cpu (if we assume it works)
2x 32mb 72pin
s3 virge dx 4mb
a151-a00 soundcard with opl3.
Also 2 HDDS and 2 cd drives that are perfect colour matches with the case.

Back onto the motherboard.. I have chosen a board for the hotswap and it appears to have the same if not very similar bios? I have attached a picture. The chip resting on the pci bracket is the suspected faulty one.

Thanks!

Similar eraseable flash rom capacity will work. I done hot swap thing, by booting with good bios then when powered carefully pull flash IC and put bad flash firmware in, and proceed with flashing utility.

I did same way using a working motherboard to create updated firmware for a Spock SCSI MCA card using downloaded firmware from ps/2 website using the flash utility by rename the files correctly.

Cheers,

I did the hotflash and the it was a success.

It did not fix the board however.

I think ASUS TX97 series had malfunction issues with one chip, which feeds CPU. It doesn't provide sufficient voltage.

Some Acorp models used it too.

This is PWM DC-DC regulator IC that sends out series of pulses through power mosfets to the two coils to generate voltages for the CPU voltages.

Could be too early motherboard but I doubt that by then when I had a HX chipset Asus P/I equipped with dual tag support, rev 3.1 supported K6-2 with no problem but K6-3 might be not supported on early versions?

Cheers,

"ready to go" = "powered on, checked the light came up", likely.

A lot of sellers don't bother with advanced diagnostics.
