Re: [LinuxBIOS] Support for recent chipset and powerful desktop CPU

You mentioned earlier that youre designing a PVR/MediaCenter PC -- lots of consumer devices such as cable boxes and digital cameras use FireWire to transfer images and video. MythTV can use FireWire[1] and according to Wikipedia almost all modern digital camcorders have included this connection since 1995. [2] I think the MSI K9N Platinum motherboard would therefore be better suited for a Multimedia PC.

[LinuxBIOS] Disassembly?
by Drew Lundsten 30 Nov '06

30 Nov '06

Although I haven't seen discussion of disassembling factory BIOS, I would think this has been discussed; why is this not routine, or effective, for these unruly Intel chipsets which can't get DRAM happy? Not that I would look forward to disassembling legacy BIOS, but if that's what it takes... Drew

YH ________________________________ From: linuxbios-bounces+yinghai.lu=amd.com(a)linuxbios.org [mailto:linuxbios-bounces+yinghai.lu=amd.com@linuxbios.org] On Behalf Of Simon Labrecque Sent: Wednesday, November 22, 2006 4:34 AM To: linuxbios(a)linuxbios.org Subject: [LinuxBIOS] Support for recent chipset and powerful desktop CPU Hi, We're starting development of a (pretty much high-end) PVR/MediaCenter which will of course run linux. Now, one of the avenue we're looking at is using standard x86 hardware (as opposed to custom built embedded hardware). Since the product will need a lot of processing power (since if we're using x86 hardware, we'll do most processing in software), we would like to use a dual-core CPU, something powerful. But it must also be low power/low heat, as you can't have a 12" fan running at 8000rpm to cool your CPU in the living now... The device should also feel "appliance-like". That means that it must boot very quickly, at least displaying some nice animated loading screen within 5 seconds. And that's where LinuxBIOS comes into play. Are there any supported board/CPU combo that would fit our needs? For an AMD board, something with an AM2 socket would be ideal as it's a recent chipset and will stay longer on the market than say socket 939, but it's not a requirement per se. We would need standard stuff on the board: USB, IDE, ideally PCI-E and pci and maybe onboard sound and video (although that's more optional than anything). If no such board/cpu combo is supported by LinuxBIOS currently, we would be willing to evaluate the possibility of hiring someone to port LinuxBIOS to the chosen platform. Do you know of any individual/company that would do such work and an idea of how much such work might cost? Thanks a lot. Simon Labrecque

For some reasons none of the last batch of messages with linubios in the cc: showed up. This is a direct test. Sorry for the noise. -- Richard A. Smith

Run it with max debug, and observe the register activity, etc. > 5. you will be able to see enough to probably figure out how DRAM is started up. This is cool and better than disassembly. How is it different in terms of copyright law? Drew

> Main problem stays: does a DIMM socket carry the right voltages? Yes, Vdd-spd should be in the range of 3.3V standard. Even if you need to take from 1.8V there are plenty of options. Drew
