The 020815s.zip is the most recent bios!
What is the problem you are having with your motherboard that you think may be corrected by a flash bios upgrade? The M810LR is a older board and is setup to use the AMD proccessor! What PcChips did was drop the R from the board designation and it became the M810L, what the bios flash does do is add support for the Athlon XP 2400+ and 2600+ and any thing else that was in the previous bios upgrades.

One of the problems with up'dateing your bios is that you must know what version the board is!

You can get a manual at the last site! This board has a AMI bios, you will need a AMI flash bios utility to do the flashing. This is the site to download the flash utility
