Cannot enable ACPI support on A7N8X motherboard

Asked by KeithHalstead in Miscellaneous Hardware, Hardware Components

Tags: acpi, a7n8x, bios, enable

Hi,

I have an Asus A7N8X2.0 motherboard. I have recently had to reset the CMOS and reinstall XP. However, I get the error message that the BIOS is not ACPI compliant and I must disable ACPI (by pressing F7 on starting Windows Setup) to be able to proceed with the install. I have v1005 (ie latest version) of the BIOS and have tried re-flashing (no errors reported).

XP installs OK but will not power off the computer properly on shut down (I get the "it is now safe" message). Also, in the Device Manager under 'Computer' it says that the IRQ table could not be found. I am also unable to boot from CD-ROM, despite setting the boot priority list to CDROM, floppy, HDD-0.

Can anyone suggest if there are any BIOS settings I may have overlooked that were reset to default values? Is there anything I need to disable/enable on any of the advanced settings pages?

The rest of my system is XP2500+, 512MB DDR333 RAM, separate DVD and CDRW, Radeon 9600, Audigy2 soundcard. Once in XP I can install drivers for the motherboard, soundcard and graphics card and these work fine. There are no conflicts in device manager. On booting up the system, when it displays the IRQ list, the last line relates to ACPI Controller and has no entries in the left-hand columns (all other entries do) - I'm not sure if that is normal or not? There are no errors reported during POST.

Many thanks,
Keith
