Checksum c718h error?

[slowjoecrow]

I have an old comp with a tyan trinity 100at board, amd k6-2 450, win 98se, and installed a geforce 2 mx 200 card. the graphics were choppy so i flashed the bios. from tyan. In the flash it asked for "save file to program" so i entered the name xxxxxx.bin then entered the same on the second line "save to file" or something. then I get a checksum error c718h. Any links or help would be greatly appriciated.
