| 172647 | 2003-09-03 00:34:00 | In Event Viewer (XP Pro), under System, I found the following service error: acpi , from Properties, I got this message details: "AMLI: acpi BIOS is attempting to write to an illegal IO port address (0x4d1), which lies in the 0x4d1 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance." What is this? Cheers |

| 172648 | 2003-09-03 01:13:00 | Microsoft say: [i]CAUSE This behavior may occur if your computer's basic input/output system (BIOS) tries to write to one of the earlier ports by using an AML [Advanced Configuration and Power Interface (ACPI) Machine Language] System IO operation region. Your try may be blocked by Windows XP because accessing these ports by using this mechanism is deemed dangerous and can cause system instability. This feature is designed to improve the stability of your computer's operating system. STATUS This behavior is by design. Contact the BIOS vendor for a possible BIOS update. |

| 172649 | 2003-09-03 01:19:00 | Thanks, godfather . I think this problem occured after I applied some Windows updates not too long ago . Is it advisable to apply the BIOS update if available? Cheers |

| 172650 | 2003-09-03 02:49:00 | I've downloaded and successfully flashed the latest BIOS update but the error remains. Do I have to live with this error :_| or there is some other ways of disabling this feature? ?:| My system is an old Gigabyte GA-6VXE+ motherboard with 6VXEP.F9 update. Cheers |

| 172651 | 2003-09-03 03:15:00 | Its worth reading up on it in Google (but you probably have by now) Search on: illegal IO port address (0x4d1) Looks like your BIOS is just not compatable with XP, as access is never allowed to 0x4d1. For the good of your health and stability according to MS. |

| 172652 | 2003-09-03 03:38:00 | Thanks again, gadfather. I just went to Gigabyte site and there is an article on this matter. Their recommendation is to re-install XP after flashing the latest update. I don't really want to reinstall Windows unless it is absolutely necessary! It's too much time involve in getting all the bits and pieces right to my tastes! :( Do you think performing a Windows repair will do the job? Cheers |

| 172653 | 2003-09-03 05:46:00 | A Windows repair will not stuff around with your settings so it wouldn't hurt to give it a try. All you have to lose is your time while it does the job and if it works, great. If not, then reinstall Windows as you have had suggested. :-) | Susan B (19) | ||
| 172654 | 2003-09-03 14:25:00 | does it affect your system to the point of instability or performance degradation? or is the only resulting factor of it the instance of an extra log message? Basically if it doesnt affect you, leave it. When you next reinstall/repair XP, the problem should disappear. And if it hangs around after the reinstall and it really concerns you, just dont use the ACPI HAL altogether. Switch back to the StandardPC HAL + APM. |

How do I configure ACPI HAL setting to use Standard PC HAL + APM? What is HAL, by the way? Thanks whetu. |
