When flashing a bios update, the program reported "an error" and crached. Result: old bios gone, re-booting impossible.
I have an identic motherboard, still having the old bios.
To use an EEPROM programmer, to copy the old bios, I must know
the manufacturer and type of the used bios chip.
Unfortunately, the motherboard manufacturer uses "own numbers".
My motherboard is a: Hsing Tech VXpro+ V5.2A(=Pcchips M537DMA33).
The bios chip is a dual-in line package 2*16pins labeled:
H.T. M21056 T9744
Does anyone know the corresponding commercial number, manufacturer
and chip type?
Thank you.

when trying to flash the mobo the flash program (awdflash, uniflash) normally reports waht type type of chip is in there.

so if you go through the motions with the second mobo without actually flashing, your answer should be there
if all else fails, try brute force :)

Going through the motions with the second mobo is risky, an identical
flasher-crash could occur. Also, the flasher-crash occurred before
reporting the type of bios chip.

Eeprom contents copiing restored the data succesfully.
Gracias ajz!

Hmm, are you sure what you are doing when you flash a bios?
If you use the flasher without any commandline parameters you will get a menu where you can load the bios you want to flash etcetera.
Also here you can try and let your chip be detected.

Dont blame you for being careful, but if you read the manual before proceeding, there is little that can go wrong.

Btw, congratulations with your succesful flash :wink:
