A bios upgrade launched around 2000. I received this from the repair department directly. This upgrade may help you to fix the problem of onboard IR port.
The file includes a BIOS rom, awdflash.exe to "burn" the BIOS in, a guide (BG5-Chinese only)to upgrade BIOS using awdflash.exe. If you need this but you cannot read Chinese, you may ask me for an English version through email.
