i have been unable to update bios with winflash or other apps, and need help with updating acer 4920 laptop bios in dos. all advice kindly accepted :confused:

ok. let me see if i can help, if you already havent fixed it. if you have bd advisor with the bundle software that came with the drive run that and attach it to this forum for me to see. Also i have heard that Gigabit mobo, do have some issues. also go to run and type dxdiag in dialog box and run it in 64bit mode and also attach that file to here so i can see.
