After many BSOD and other errors to numerous to mention and thousands of erros.... I desided to revert back to the WAK86-116 Bios for the AOpen AK86L mobo.... No more errors on Boot, No more problems with many things.. memory glitches, hangups, DVD's showing as CD-only, DVD failure to show empty when CD/DVD removed... This might help on any of the AOpen mobos, if you have minor errors start after you have upgraded your Bios...
I sure hoipe you keep the last Bios...
PS: I can not access Aopen (usa or tw) to see if they have a newer BIOS than WAK86-118....
