Re: computer booting problem

Hi, You backup Lithium battery may require replacement. The CMOS/BIOS not remembering you prescribed setting is an indication that though the settings were saved, they were not retained and therefore when booted would display the "F1" "Del" choices. Even if the new DVD writer is configured/attached as Primary Slave, as long as you set it to be the first bootable device, the computer would boot from the DVD first. Again, this is done in the CMOS/BIOS setup (as you have done). But the CMOS/BIOS must execute this if retained in its memory. In some rare instances, even with a new battery, this problem do occur. The issue is no longer the battery but discreet components along the memory B+ line such as a reverse protection diode, surface mounted jumper resistor. Hope this be of some help/idea. Post back how things turn up or should you need additional information. Good luck and kind regards.
