Phoenix BIOSOS? 394

jhfry writes "In an interesting development by an unexpected source, Phoenix Technologies is releasing a Linux-based, virtualization-enabled, BIOS-based OS for computers. They implemented a full Linux distro right on the BIOS chips, and by using integrated virtualization technology, it 'allows PCs and laptops to hot-switch between the main operating system, such as Windows, and the HyperSpace environment.' So, essentially, they are 'trying to create a new market using the ideas of a fast-booting, safe platform that people can work in, but remain outside of Windows.'"

          He basically makes the argument that TPM is a dual-use technology: it can be used for good or evil. Problem is, the evil uses could easily be disabled without impairing the good uses... but that hasn't happened.

          "Remote attestation" is for DRM, plain and simple. It's evil. There is no reason I'd want my computer to produce a report of what software I'm running without giving me the ability to change that report before it's sent out. That feature is useless for me as a user; it's only useful to third parties that want to restrict the software I'm allowed to run (e.g. by refusing to send me a video stream unless they know I'm using their preferred player).

          If they removed remote attestation from the TPM spec, or simply put a switch on the side of the computer so the owner could forge attestations whenever he felt like it, it wouldn't be evil. So the question is, if Trusted Computing is such a boon for users, why does it still have features that only serve to undermine those very users?

            Or you might consider a slightly bigger world than your basement and uses for computers besides downloading porn and playing WoW. Remote attestation might not be something you care for, but if you were designing an ATM system you might feel differently about the ability to know, with a pretty high confidence, that the remote terminals are uncorrupted.

            You are stuck on the idea that it is YOUR computer and that will always be so, that the person in front of the display owns the machine. But that just isn't true in a great many scenarios. I'd really like a system that allowed me to know if one of the workstations around here had been compromised. All of our machines are 'mine' in the sense I'm the one responsible for them, the employees sitting in front of em just use em.

            Even remote attestation can be used for either good or evil. The key is to resist when big media tries to use it for evil. And it's evil because the machines aren't TimeWarner's yet they want to assert ownership over them just because they are displaying their precious IP.

              Fair enough. But if I were designing an ATM (or a kiosk, or any other public-facing terminal where remote attestation might have a legitimate use), I could put whatever additional hardware in there I wanted. I'm already adding a keypad, card reader, touch screen, etc. so why not one more thing?

              Remote attestation isn't something that needs to be built into the average PC. On a typical user's desktop, remote attestation doesn't really have any legitimate uses, only evil ones.

              If those workstations came with a switch on the side for forging attestations, and you didn't want users doing that, you could simply disable the switch. Just like you can already disable CD-ROM drives, USB ports, or whatever else users might use to compromise the workstations.

                As a system administrator, I disagree in the strongest possible terms. I'd love to be able to have the domain clients here restricted to an authorized software list. I could let users install things they needed or wanted instead of having to do everything for them, but I could restrict the list of available code to things I'd verified were safe and wouldn't cause system issues, security problems, etc. It'd also offer significant protection against resident malware. It'd be great.

      Very different. What Phoenix is doing is pushing Windows into a VM, permanently. The machine boots Linux from the BIOS and loads Windows into a VM container in the background while you have a basic Linux desktop to browse the web, read email, etc. You can flip between Windows and Linux with a hotkey. But Windows stays in the VM. This offers a hope of eventually containing the menace from Redmond. The question is whether Phoenix will want to go there.

      Imagine a real firewall dropped between the virtual NIC in Windows and the real one. Even better, just forget the network in Windows for most uses, use the Firefox on the 'other' more safe system that is a hotkey away. Push this tech a bit more and have seamless Windows(tm) windows running rootless on the X side. Now we don't even need to worry about two different displays. Basically, this tech offers the potential to blur the line between Windows and a real Internet ready system in ways impossible to predict. This could erase enough of Windows' defects to keep it viable or it could remove enough of the reasons to run Windows it hurts it. But Pandora's box is open and it will be interesting.

    DOS was a BIOS based OS. It passed a large number of its calls directly to the BIOS. We all know how well that worked out.

    That said, I would rather have a read-only, default, fallback, usable OS in the system firmware. You know, something that could be used for:

    1. OS installation.
    2. Basic networking.
    3. Backup and recovery operations.
    4. Performing basic system utilities.

    The PC is one of the few platforms where the hardware is actually useless to the end user without an installed operating system. Reflashable BIOSes further compound the problem by allowing a software command to render the hardware unbootable and unrecoverable (that is, unless you happen to have a FLASH programmer and another computer lying around...). The PC has perhaps the worst architure and implementation of any major platform, and it's about time they did something to fix that.

    In fact, with the falling prices of flash, why not just flash a Linux kernel into the BIOS?

    1. A bootable, usable Linux system with BusyBox can fit into 4 MB of flash.
    2. A 64MB flash (possibly much less) could support the above, plus MicroWindows or similar.
    3. Why bother having a separate OS when the kernel could fit on the firmware?
    4. Let the rest of the system - libraries, apps, configuration, etc... reside on the disk, but keep the hardware related parts (i.e. drivers, etc...) on the firmware itself.
    5. With kernel drivers *in the hardware itself*, one would never have to worry about getting the correct driver, etc...

      For security reasons. Your firmware OS might have exploitable privilege escalation bugs, so you don't want to run untrusted software under it directly, only in a protected virtual machine environment. That virtual machine environment must have its own OS, and that would be a disk-based OS which is easier (and safer) to update in the event that security holes are found. It's preferable if the whole boot environment is as near to possible as read-only, just to reduce the possibility of malicious exploit. It shouldn't even be possible to re-flash the system without physical intervention (such as changing a jumper).

      With kernel drivers *in the hardware itself*, one would never have to worry about getting the correct driver, etc...

      This is true for the flash-based OS and the built-in hardware, which is why you can boot into a usable system so long as enough of the hardware is integrated on the motherboard. Don't forget plug-in cards and external peripherals, though. There's no avoiding the need for those drivers, in general.

    Most of these comments make me want to puke. I've worked on everything from OS and drive code to firmware/bios code. The one thing I've learned is that you _DONT_ want a heavyweight BIOS/firmware. There is a certain appeal to having a system which ships with a hypervisor, and a heavyweight BIOS that can do everything from configure your memory subsystem to allow remote web based console visualization. On the other hand, you have massively complicated and restricted your system. Everyone thinks that putting all this functionality on the motherboard is a good idea because you only have to flash your BIOS once in a while.

    If you want an example of where a heavyweight BIOS leads to, you only have to look at the EFI or OpenFirmware specification. They are so full of technical holes and complexity that nothing works right, and in the case of EFI you have to update the drivers in the BIOS as often as you have to update them in your OS. So, instead of one driver you have two.. Plus flashing cards, or upgrading firmware drivers is _NEVER_ as easy as installing a new OS driver. There is always some technical or human factor that kicks you in the rear.

    I've had this discussion with other people in the field, and basically aside from the zealots a lot of other people agree. The core concept of the PC BIOS is really close to the ultimate design. Of course its 25 years old, so its gained a lot of cruft and bugs, but if you were to start over the goal should be a modern version of the BIOS rather than some embedded OS, hypervisor, etc.

    What you want is fairly lightweight bootstrap and POST utility to get the machine far enough along that you can fetch the hypervisor, or OS from the disk. This means you have to standardize the API for functions like read sector, print text on screen, read data from keyboard etc. You also have to provide the ability to extend or override those functions from a firmware blob sitting on a SAS adapter, or video card.

    This is not an argument against service processors (an entirely separate topic, that people often get confused about), but rather an argument that I don't want my motherboard to try to standardize a hypervisor or OS. I want that decision left up to me. Generally the poor dumb customer doesn't want it either, they just want a machine that runs windows, linux, OSX or whatever, if they are even that detailed. The OS in the firmware people forget that firefox has been sending me weekly (daily?) patches lately, and its likely that over a few years timeframe the later versions of FF won't even run on some older firmware restricted OS without the original vendor providing upgrades. This puts the motherboard vendor in the position of being the support infrastructure for the _WHOLE_ computer. Something i'm sure the majority of them are unable to provide, even though they may have a couple people who can port corebios/linux/etc to run on their hardware.
