So it's a Linux distribution that is utilizes a Debian Wheezy base with extensive modifications. That's no different with Microsoft using a modified Windows for the Xbox. Or Sony using modified FreeBSDs for the PlayStations.
it's a RT kernel distro with steam preinstalled and integrated to remove every bit of lag from games. the fact that i see desktop is bothering me more, especially since they use RT. hope it only runs when you leave out and logs out when you go back to BPM in order to conserve resources. i'd truthfully prefer something like Boxes integrated in steam and access remote machine, but hey... can't have everything. then again... when you think, having console and development seemingly integrated might be downright game developers tastes.

Originally posted by ricequackers View PostHonestly, what's the point in using Coreboot over UEFI aside from ideological reasons? The latter is standard in off-the-shelf motherboards (remember, they want Steam Box to be "just a computer"), it's supported well enough by Linux and the boot firmware is largely an irrelevant concern. For secure boot, they'll either disable it or preload the SteamOS bootloader's keys into the firmware.

UEFI have nothing to do with signatures.
SECURE BOOT (which is JUST an extension to UEFI), does not either...
Its just OEM's who may not bother to add any non-MS keys... (That's why getting keys from MS is so smart)

It is not "just" ideological. It has to do with the fact that UEFI (sadly) is bug infested, also due to the fact that even the reference implementation is way too large. It is full of nonsense also (vendors love to put in animations of spinning fans, "3D" setup menus and other crap). It has to do with performance. It has to do with royalties / licenses to be paid for this mess. And last but not least it has to do with security and privacy. A firmware that is so huge like the Linux kernel without drivers, wow, that leaves a lot of open surface for attacks / security holes, general bugs or intentional backdoors.
So Coreboot would probably be not the worst choice. They can add some Seabios payload in case somebody needs to install Windows on it (which afaik still does some BIOS calls).Stop TCPA, stupid software patents and corrupt politicians!

Phoronix then made game benchmarks and did not notice significant differences but perhaps Valve did.
