Thanks for your response.
Yes, the 310S can be flashed to its Intel BIOS.
The D845GVSR motherboard has a BIOS recovery jumper. The information is on page 46 of the D845GVSR manual.
Use the procedure described in the first post of this thread.
Replace the BIOS files with the ones for the D845GVSR mobo.
I have checked the Intel website and indeed version P20 of the BIOS, dated 5/4/2006, is available.
Make sure to create the boot disc (USB flash drive, CD or floppy) with 16-bit DOS. Microsoft DOS v6.22 is recommended for maximum compatibility. The reason is that the BIOS boot blocks can only deal with 16-bit DOS. Check
http://www.bootdisk.com for 16-bit DOS.
Intel Thrasher is just a descriptor used instead of the mobo model. Like with my board, it is commonly referred to as El Paso 2.
OK so I hope the above is enough to get you on track.
Please don't hesitate to post back or PM me if you need more detailed replies.
As for your memory problem, I do not think flashing to the Intel BIOS will help. I don't believe it is like flashing a DVD writer to add compatibility for more media.
Check the speed of the RAM you are trying to install. Maybe it is too slow?
The manual for your board is also available at the Intel website as a PDF. Perhaps you should DL the user guide and check the memory specs, then try again? You have to go there to get the BIOS file anyway.
Take a stick of the original memory with you to the place where you plan to purchase the RAM upgrade. The store can elucidate the part number and determine compatible options.
Some memory vendors (Kingston, PNY, Crucial, Mushkin, etc.) have online configurators that display compatible part numbers based on motherbard make and model.
Please look into a memory upgrade one more time.
