    Sorry, I didn't realize that it was SOIC. I hadn't read the DATA Sheet you referenced. There are "Test Sockets" and adapters for programmers but I don't know how those would fit on your board. The good thing is that with only 8 pins, the soldering/de-soldering shouldn't be that tough with a fine or chisel tip iron and good light and magnification,

    Here is an update to this in case anyone is interested.

    I finally decided I had the time and nothing else to loose, so I unsoldered the chip, shoved it in my flasher and flashed the 6.01 BIOS image onto it. Then I re-soldered it back onto the board. It definitely was not the best solder job, the chip is sitting funny and I can't get it to line up right, but all the legs are firmly attached.

    Fired up the server and it posted! So victory to me. The server is 100% functional again, running the 6.01 BIOS on it, and I do not plan to change that. So yeah, chalk one up for the good guys!

    Fyi, on some older intel desktop boards, I've had luck powering on the board with the cpu removed to program the chip.

    My method is, pull the cpu/fan, and then force power on the system using a jumper on the psu power on pin. then program.

    I've recovered a lot of dh61 series like this.
