OS: Win XP sp2
Dell Dimmension B110
The first symptom was the onboard network connector stopped working. On reboot the blue bios screen appeared. the error number is:
0x000000A5 (0x00010007, 0x00000038, 0x00000000, 0x00000000)
I have already tried removing the battery on the motherboard, and flipping the two pin connector inorder to clear the settings.
