My assembled computer (intel p4 1.6 with gigabyte motherboard 845 gv/gl) is facing a strange problem during booting.during booting sometimes it is showing "checksum error.....defaults loaded,f1 to continue,del to enter setup".when i press f1 the floppy changes to first boot device and cdrom rolls back to third boot device and hard disk remains as the second boot device.but i prefer cd rom as 1st boot device with floppy as the third.also recently i replaced my cdwriter awith a dvd writer.is the problem occuring because of this?but i have selected the dvd writer as primary slave.is it a problem with the mother board battery?please note tjhat i have been using it since 2004
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.
