Most of the older gen. nF2 boards suffered the bios corruption issue but the newer gen. boards do not. I experienced it on an older Soltek SL-75MRN-L but was able to recover the board by popping the battery and bios chip for 10-15min, not once but twice. Many others weren't so fortunate and they had to resort to hot flashing, ordering new chips, or RMAing their boards.
