Question While performing BIOS upgrade for X9DRG-QF motherboard with official release BIOS, I noticed the "allocating memory error" and the system interrupt immediately. Any reason? Answer Please create CONFIG.SYS configuration file under DOS to root. Also, add "device=himem.sys" inside the CONFIG.SYS file. You can get the Himem.sys from DOS utility or FreeDOS image. Once when you complete this, you can perform BIOS upgrade successfully. Was this FAQ helpful? YES      NO Enter Comments Below: Note: Your comments/feedback should be limited to this FAQ only.
