Yes, but manual flashing is advanced and risky. Typically, you would not invoke biosdsi9.rom directly; instead, the OEM’s flashing tool (e.g., phlash16.exe , WinFlash.exe , AFUWIN.exe ) would recognize it as the source file. However, if you need to force-flash the file (e.g., to recover a bricked board), here’s how:
