vista installation load failure acpi not compatible

Hi, i tried to install Windows VISTA Beta 2, on my home PC, but immediatly after booting from intallation DVD, just after installation environment loaded it's files i got the following error message:
Info: "Windows failed to load because the firmware (BIOS) is not ACPI compatible" Status: 0xc0000225
I have checked characteristics of my motherboard (it was produced in 2001, but i'm sure that it supports ACPI) - here it's specification, which approves ACPI compatible.

Anyone got the same problem? Could you please specify what certainly is not supported by my motherboard and advise some solving of the problem? May be BIOS reflash would help or my computer is absolutely not compatible with VISTA?
Thanks for any help!

Wouldnt surprise me if that board is not fully ACPI compliant, as it doesnt even support DDR RAM above pc 2100 or even support 8x AGP. A BIOS flash may help...but you might have to bite the bullet and buy a new board if you want to run Vista.

Vista should run. It scales to older hardware much better than XP did.

Hi,
Have you flashed the BIOS since 2001? It may not be fully compliant. Check with the motherboard manufacturer for this.
