I've got the same problem, my system configuration is:
Ram : 1333 x 2GB
uP : E5800
My Bios is: TXG4110H.86A.0037.2010.0222.1734
I can manage to dont get the ACPI error at first,
I still fully installed my SO but I hope it's gonna pass.
I've just in Power put this configuration:
Af Power Failure Stay Off
W o L f S5 Stay Off
ACPI Susp Sta S1 state
S3 State Indicator OFF
S1 State Indicator OFF
P P Management Disable
W S f S5 Disable

I hope this will help,

I would be great if Intel can tell me if I installing Bios 53 do the trick or it can go worst
i installed a 4500 dual core and the machine worked fine. i then upgraded the firmware and put the 5800 processor back in and all is well.
i´ve got the same problem with the acpi at begin instalation in XP, VISTA AND WIN 7 , i´m upgrade bios and don´t work
intel e5800 processor.
What processor was in the motherboard at the time of flashing the BIOS and what BIOS version are you attempting to flash from? I think it may be key that the CPU which is installed, is already fully supported before attempting to flash a newer revision to give greater CPU compatibility. Perhaps your supplier can help out and perform the update if you don't have a suitable CPU?
