Uniflash is a specific tool with a specific purpose - flashing the whole chip. That makes a lot of sense as EEPROMs are ROM not RAM, so you can't just do random access writes to them.

The way to go about flashing a specific bit of the chip is to take a dump of the EEPROM, then use an editor to put your small binary where you want it, and subsequently to flash it all back again. So IMHO you shouldn't be looking for another flash tool but for a BIOS editor to manipulate BIOS images.

Nice, interesting. Any hex editor would do? Is there a "standard" one?

I was thinking to use this process to flash a XT-IDE binary and then use it with a network card on an old computer.

I'm using XVI32 or the editor that's part of the TL866CS software.

Well, I've got a spare 27128 here with an old copy of XTIDE Universal BIOS. I could send you that in an envelope, if you like. 😀

I've always found flashrom works well, but likely you will still need to make sure the image size matches the chip size.

Thank you very much Jo22! I will PM you.

That program seems pretty, pretty, pretty good, I'll check it out Malvineous, thanks.

Romflash forever.flashrom is the most guaranted util to this day.Imhave used it successfully in a lot of mobos.
