I have a computer with a BIOS that doesn´t support ACPI. I tried to install Windows 8 but the setup said I cannot install Windows 8 without ACPI. After some research I found out that this is since Vista.

Is there any option to install Windows 8 even if the BIOS doesn´t support ACPI?

  • Paedow can you do me a favor and correct some? It'd only be one change and they don't allow that but the grammar nazi in me can't stand it. – Griffin Mar 09 '13 at 16:22
  • @Griffin: you can edit questions for spelling etc. See the "edit button" at the end of the question. – Xavierjazz Mar 09 '13 at 16:26
  • @Xavierjazz I can yet you need to edit a certain number of characters before it will allow you to click the done thing. At least that's what it has done in the past. – Griffin Mar 09 '13 at 16:30
  • A MacBook Pro doesn't even have a BIOS, but Windows 8 still runs on it. I'm running it. – pratnala Mar 09 '13 at 16:58
  • @pratnala: So what's your point? All PowerPC Macs used Open Firmware and all Intel Macs use EFI. (U)EFI is fully compliant with ACPI tables/firmware. The latter is used at runtime, whereas the former is mainly used during the bootstrap process. So Macs not having a BIOS is irrelevant since they have its successor which is EFI, which Win8 of course also fully supports (not to mention Apple's EFI implementation is [non-standard and buggy](https://help.ubuntu.com/community/UEFIBooting), which is why the Linux kernel has [patches](https://lkml.org/lkml/2011/6/8/322) to work around them). – Karan Mar 10 '13 at 19:22

No.

Windows used to support APM (and you could in fact even force a specific HAL version at install time), but with Vista they dropped it. Build 5048 if you want to be specific.

Anyhow, if your system is so old not to support ACPI, I'm really doubtful it could even meet the other minimum requirements for W8 (namely SSE2 and NX bit). Nevermind.
