vista installation load failure bios not acpi compatibl

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!

may be acpi compat, but did you turn it on in the bios. check the manual.

Hi, thank you for help! I fixed this issue - the problem was really in BIOS option: just ACPI was turned off in BIOS... i truned it on and installation started! :-)
