Based upon further troubleshooting and research it appears this problem may be an AMI BIOS issue. Although these are relatively new machines, I downloaded the latest AMI BIOS (061214s.ROM) for the motherboard from the manufacturer's website. I flashed the BIOS and then repeated the steps that previously resulted in the CMOS becoming corrupted: Boot Ubuntu Live CD, then reboot into Win XP. With the new BIOS, the CMOS did not become corrupted and networking functions properly in both Ubuntu and Win XP.
So, the resolution for anyone with this problem is to flash the BIOS to the latest version and clear CMOS. -- CMOS corrupted after running Ubuntu v6.06 https://bugs.launchpad.net/bugs/102529 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
