SYMPTOMS

BIOS SETTINGS

Because the BIOS settings have not been problematic in the last 3 years I do not think they are the problem, however, if they are a problem:

QUESTIONS \ REQUESTS

  1. Are there any other additional test / diagnostics to determine root cause of problem?
  2. If you have seen / solved this problem please indicate this in your response
  3. If your diagnosis is mapped to corrective action already posted, a link is appreciated.
  4. What does not being ACPI compliant actually mean: how do I verify compliance?

It's odd that after 3 years the machine is seemingly out of nowhere 'not ACPI compliant'

BIOS UPGRADE ATTEMPT

Despite the indication of success, attempt to upload the image via BIOS and CD is not good: no BIOS image on monitor. I am not sure how one would try to do this again without a good working BIOS.

    Have you tried enabling ACPI S3 Hard Disk Reset? Have you tried updating the BIOS? What have you tried so far? – theJack Aug 11 '16 at 5:23
  • Good questions: Yes: attempt to enable ACPI S3 results in the same symptoms. Attempt to Flash ROM seemed successful (see photo above), however booting up the machine: no BIOS observed on monitor. @downvoter: If voting down a post, that's fine: leave some constructive feedback. – gatorback Aug 11 '16 at 6:51

    msdn.microsoft.com/en-us/library/windows/hardware/… here is the issue: If Parameter 1 equals 0x11, the system could not enter ACPI mode. parameter 2 = 0x7 which is checksum error: A pointer to the table that had a bad checksum – magicandre1981 Aug 11 '16 at 7:43

Despite a shaky start upgrading the BIOS, it seems that the problem is resolved. It is a little puzzling that XP did not complain about the BIOS for years and suddenly the BIOS is unfit. Wondering now if BIOS was somehow corrupted and how to prevent corruption.

BIOS Upgrade Link: the download must be unzipped on Windows box and the .iso file can be burned to a CD and presented to the current BIOS for install.
