BIOS wrongly flashed on Data Expert board
I flashed the BIOS (Rev.2.1) of a Data Expert motherboard "EXP8449" (486) with the flash utility for "EXP8551" (586).
Got message : "Flash EPROM Programming error. System will NOT be usable unless existing Flash EPROM is replaced with new Programmed Flash EPROM. Put off system power"
After power off/power on : no lights or screen activity at all, no HD startup.
Then I cleared the CMOS : put connector J1 at 1-2 (2-3 = Normal) and powered on.
Nothing happens (guess this is normal?).
Only when I leave connector J1 all OPEN (1-2-3-4 OPEN), then I get a bootable system.
But I have to run setup again after every power off/power on. I can't manage to permanently save the setup even if I do a "save setting and exit" at the end of the setup process.
Putting connector J1 back to "Normal" (2-3) results in the same situation where the system doesn't do anything at all.
What to do ?

Thank's for the explanation.
But what I forget to tell is that I also tried to reprogram the BIOS with the correct flash utility, but with the same error message and the same result.
Does this leave me with the option to physically replace the BIOS-chip itself ? (Which is not an option because I don't think I can find a new one).

Yes, but the damage has been done. It's very likely that the flash programming code (which is also stored in the memory) has been damaged as well.

Yes. If you have a copy of the original BIOS image or can download a good one from the MB web site, someone with a hardware flash memory programmer can reprogram it for you.
