That's an older board...good luck if you can't find any alphanumerical information on the board. I would start googling anything printed on it, there is usually something somewhere on the board.

got 2nd hand the xcel named board a yr. or so ago. at the time there was about zip info on it. searching "Xcel2000" eventually led me to PCCHIPS, unfortunately the bios info "M741-LMRT-H" is a designation PCCHIPS does not, and, as best I can tell, has never used. go figure. the *.rom/*.bin file that the techs there indicated to be used resulted in an error "file too big". the "help" line that PCCHIPS had open went dead after being so informed. presently it's moot point, the board's effectively dead. in desperation the bios was flashed with the wrong file.
thanks for the heads up anyway.
