Intro To Intel's Next-Gen BIOS Architecture

Posted by timothy on from the redefining-basic dept.

An anonymous reader writes "This article introduces the Intel Platform Innovation Framework for the Extensible Firmware Interface (EFI), which is intended to provide an alternative to BIOS that will allow for faster booting, manageability, and additional features. According to the author, there has been rapid evolution of the personal computer platform since the 1980s. These advances have included order-of-magnitude increases in performance, ease-of-use, storage capacity, and connectivity. But there is one element of the PC that has not changed for the past 23 years -- namely, the BIOS (basic input/output system)."

    The awesome backward compatibility of the PC architecture is one of the main reasons it's the most popular personal computer platform. Besides, there have been tons of advances in BIOS technology over the past 20 years. Sure, the basics are still in there, but even 5 years ago you couldn't boot off a USB key fob or even over the network (PXE) on most motherboards. 10 years ago power management was basically non-existent and things like ACPI and APIC were years away. Extend, don't just throw it away. If you're going to get rid of it then at least adopt Openboot firmware like Macs and Suns have.

      On the Openboot prompt you can do this:

      OpenFirmware (defined in IEEE 1275 as updated in 1994) is no longer being maintained. It was withdrawn by the IEEE Standards Organization in, I belive, 1999. The rights to the document were sold to Global Engineering.

      This does not mean that OpenFirmware is dead. On the contrary, there are several commercial implementations available. It does mean that it is no longer considered a "standard", though.

      If you'd like some more information on OpenFirmware, you can visit the OpenBIOS web site.

    EFI allows really big enhancements to the bootup procedures. Everything that happens from POST onwards in BIOS's today is a huge waste of time. (Especially on windows PCs, haha). All that time spend ennumarating ISA slots (what ISA slots?), floppy drives, hard drives, etc etc is a big time blowout.

    One of the biggest steps in moving from that 1-2 minute bootup time on a PC is getting rid of the 10 or so seconds we spend letting the BIOS do its thing.

    Why shouldn't you hit the "on" button and see the logon screen instantly? With more and more advances like EFI and solid state storage this might be closer than you think.

    Otherwise you have to patch Lotus 1-2-3 to make it work.

    Seriously though, it seemed to me that at first this should break backward compatability but why couldn't BIOS emulation be plugged in as an EFI driver? All it has to do is provide the same software interrupts and it wouldn't even have to be loaded unless your OS needs BIOS to boot. Just because this "framework" isn't natively backwards compatible doesn't mean it couldn't be made backwards compatible.

    Okay, so EFI can emulate standard BIOS through a module. Which means that it can also obviously emulate OpenFirmware.

    Since OpenFirmware is also totally programmable, does that mean that OF could emulate EFI?

    It'd be interesting to see if future video cards decided to support EFI instead of x86-specific BIOS code. One of the big problems with getting video cards on the Mac is that they use x86 BIOS code which means that vendors need to make two versions, one PC and one OpenFirmware, and since the PC market is so much bigger the OpenFirmware version is usually 2-3x as expensive (and because of the development effort in making the OpenFirmware version, ATI et al do whatever they can to prevent people from just flashing the x86 version of the card with the OpenFirmware firmware).

    It sure would be nice to not have to pay $200 for the Mac version of a $75 Radeon...
