Critical security flaw found in Lenovo PCs... again
If you are sick of hearing about how Lenovo Machines are riddled with security flaws, then this ain't the story for you. Security researcher Dymtro "Cr4sh" Oleksiuk claims to have uncovered a flaw in Lenovo machines that could let attackers circumvent Windows' basic security protocols. According to his post on Github, the vulnerable firmware driver was copy-and-pasted from data supplied by Intel. His concern was that other manufacturers might have adopted the same code -- with at least one HP Pavillion laptop from 2010 already identified as packing the flaw.
New SteamOS beta tempts more testers with support for older PCs and dual-booting
Valve released its SteamOS beta with a warning: Only touch this if you know what you're doing. While that surely did something to separate true testers from the first wave of eager users, there were a few problems. Even the qualified needed a relatively new machine with UEFI, and a dedicated one at that, given attempts to make the OS a secondary boot option were troublesome at best. However, a fresh beta that folds in efforts by both Valve and the community is now available. On top of fixing the aforementioned issues, thereby welcoming more to get to grips with early SteamOS, other major updates include partition, recovery and DVD install support. This doesn't mean it's ready for general consumption, though, so we'll point the brave to the source link below and swiftly wash our hands of you.
Linux Foundation finally gets Microsoft signature on secure UEFI bootloader
Whatever hoops the Linux Foundation had to waddle through to get an MS-signed bootloader for use on Windows 8 hardware, it appears to have worked. Whereas Ubuntu and Fedora already had UEFI Secure Boot support, and there was the Shim bootloader and other fixes for smaller distros, this official solution promises to be more user friendly and universal, albeit with a few caveats that are described by MJG59 at the link below. Once you're sure you want it, head over to the source with a USB key and do the honors.
Linux Foundation vet explains setbacks in getting a Secure Boot key for Windows 8 PCs
Linux fans wondering why they still don't have a friendly UEFI Secure Boot option for Windows 8 PCs won't get a solution in hand this week, but they'll at least get an explanation. The Linux Foundation's primary backer for the alternative OS efforts, Parallels' server CTO James Bottomley, has revealed that Microsoft's requirements for signed, Secure Boot-ready code are tough if developers aren't entirely onboard its train of thought. The Redmond crew demands a paper contract signature (remember those?), agreements on work beyond the relevant software and a packaging process that complicates attempts to use open-source tools. Bottomley has already overcome most of these challenges, although he's still waiting for a Linux Foundation-specific key that should theoretically clear a major hurdle. Whether or not that leads to a remedy in days or weeks is up to Microsoft; in the meantime, we'll take comfort in knowing that a signature is so far a convenience for booting into Linux, rather than a necessity.
Linux Foundation proposes convoluted solution for UEFI Secure Boot
With Windows 8 Microsoft is pushing manufacturers away from a traditional BIOS to UEFI with Secure Boot. But that poses problems for alternative OSes like Linux, because UEFI requires any software have a signed certificate. The Linux Foundation has been looking for a solution and thinks that it may have one. The proposed work around is a little convoluted and surprisingly involves obtaining a Microsoft signature for a new barebones bootloader. This wouldn't actually boot Linux or any other OS actually. Instead, it would then start a second bootloader, the one associated with your OS of choice. It's a little messy, but it should mean that the signed bootloader will be a catch-all solution for any operating system. Of course, it could take a while for the Foundation to actually obtain a signature from Microsoft. So "Designed for Windows 8" systems might not be able to run Linux right away, but rest assured a solution is on the way.
Microsoft details Windows 8's pre-boot world, helps you skip the F8 F8 F8 routine
Microsoft has been going into very exacting detail as to how Windows 8 works, but one area it hasn't explored much is what happens before you even see the Start screen. As user experience manager Chris Clark notes, the days of mashing F8 repeatedly to reach a pre-boot configuration are (mostly) over: you can invoke it either through an "advanced startup" in settings, through Start menu shortcuts or, if your PC is truly sick, let it show automatically. At least on systems blessed with UEFI instead of an aging BIOS, you'll get a lot more to tinker with as well, including going straight to the command prompt, recovering from a system image or booting from external storage. The emphasis on choosing your environment before you hit the power button is virtually necessary. A Windows 8 PC with a solid-state drive leaves just a 200-millisecond slice of time for any user input, and Microsoft would rather not have users caught in an infinite loop of restarting their systems as they unsuccessfully try to boot from USB drives. You'll likely discover the pre-boot space first-hand when the OS ships later this year, but for now you can check the source for more.
Windows 8 ditches '80s BIOS boot for streamline UEFI
Every time we reboot our computers, that scrolling code takes us right back to the days of War Games and Tab. Bringing us into the 21st century, Microsoft has decided to ditch the old boot by beautifying the whole experience with a graphical menu. Windows 8 will shift from the standard fugly BIOS system to a Unified Extensible Firmware Interface (UEFI) -- giving users a high resolution logo and a graphical menu to gaze upon while powering up their PC. Besides just looking better, the menu lets you boot to a different disc, OS or USB drive using pretty pictures and words as prompts. If you're into a little self-inflicted eye torture, you can always pull up the command prompt menu from nightmares past. Check out the throwback video tribute to the computers of yesteryear after the break. Update: Just to clarify, Microsoft isn't actually building flashing mobos, but it's pushing towards UEFI to achieve "significantly richer capabilities" while booting. Update: Microsoft isn't actually building flashing mobos, but it's using its considerable industry weight to push manufacturers towards UEFI to achieve "significantly richer capabilities" while booting.
MSI demos X79 motherboards with PCI Express 3.0 and UEFI BIOS at IDF 2011 (video)
While MSI wasn't quite ready to publicly divulge all the details of its forthcoming X79-based motherboards, it was more than happy to give us a teaser. We were shown three upcoming models from the company at IDF, all toting PCI Express 3.0 slots, overclocking buttons and that snazzy UEFI BIOS. The latter makes changing settings a snap, and is carried over from the company's existing Sandy Bridge boards -- it even comes with a button that launches a browser, but unfortunately the machines in the booth weren't configured to support it. We'll know more in Q4, but in the meantime a gallery awaits you below, along with a video after the break. Myriam Joire contributed to this report. %Gallery-134332%
MSI reveals mad Sandy Bridge motherboard with eight PCIe slots, eight USB 3.0 ports, and three BIOS chips
Straighten up and salute the Big Bang Marshal, MSI's attempt at redefining the term "overkill." This XL-ATX board packs a total of eight PCI Express lanes (though it only has the bandwidth to simultaneously feed four x16s or eight x8s -- relevant if you're crazy enough to think about using more than four GPUs), three separate BIOS chips, extra 8-pin and 6-pin 12V power intakes, and a thoroughly excessive set of power regulation components. The less extremely minded among you will appreciate having a full array of eight USB 3.0 ports on the back, though we can't get over the measly four DIMM slots on offer. Word is that features might change before the Marshal goes to market in the first quarter of next year, so let's hope more room for your RAM sticks is among the tweaks between now and then.
Swedish website tries out Sandy Bridge motherboard with BIOS-replacing UEFI
We haven't heard a ton about the Unified Extensible Firmware Interface (or UEFI for short) since a rumor cropped up back in June suggesting that MSI would be introducing it on its Sandy Bridge motherboards, but Swedish website SweClockers has now actually gotten it hands on a motherboard with working version of the BIOS-replacing firmware, and delivered our first real look at it. The biggest difference, as you can see, is a significantly more user-friendly interface, but there's also a few other considerable advantages over a standard BIOS, including faster boot times and the ability to boot from drives bigger than 2TB. Head on past the break to check it out in action, in Swedish. [Thanks to everyone who sent this in]
MSI replacing BIOS with UEFI firmware interface sometime this year?
The Unified EFI Forum is a trade group that includes Microsoft, Apple, Intel, and ARM. The goal? To develop and implement UEFI (Unified Extensible Firmware Interface). The specification replaces BIOS as the software interface between your computer's hardware and OS, doing away with several limitations of the BIOS firmware interface in the process. Unlike the old, dependable BIOS, however, UEFI comes with a flashy-mouse driven interface; and instead of being written in assembly, it's written in C -- which means that it needs more resources, although it's also a lot more flexible. According to an article on THINQ.co.uk, MSI will introduce the spec on Sandy Bridge motherboards "towards the end of this year." Also according to THINQ, Seagate has stated that UEFI is "an essential requirement" for PCs with boot drives larger than 2TB. That said, it doesn't look like the classic text-based firmware is disappearing any time soon: most existing motherboards simply don't have the overhead to support its flashy successor. Besides, manufacturers have spent too much time developing their own custom BIOS and hardware features to throw 'em away just yet. Update: Of course, this is but a brief introduction to the topic. Special thanks to Brian Richardson for pointing out this post at Intel that goes into much greater detail.
