Re: [coreboot] i would like to get coreboot working on VIA PC2500E

ok - i have just tried to be friendly and let you ask information needed must apologize if tones of my messages are wrong as i'm not native english and it may affect nuances of my writing or how it sounds to you - the basic issue is that after following your pages, coreboot won't boot - i have not yet tried to get output w serial console but try to follow previous hint to do 'make crossgcc' - as i try to do 'make crossgcc' the system appears to go to loop = now it has been trying for an … [View More]

Please paste what is written on the console. (Including log files is always recommended.) As all the tools get compiled from source it is to be expected that the CPU is used a lot.

Make sure to build everything using the reference toolchain. Run make crossgcc in the coreboot directory. Then post the debug log (serial output) from coreboot. //Peter

Hello i bought brand new pc500e from ebay as i really like via - and have been interested in coreboot for a long time. board is exactly the same as in Uve Hermanns image - http://www.coreboot.org/VIA_pc2500e . i have been using Linux for ages ( from kernel 1.2.13 or so ) and built my stuff mostly myself using some aschetic distribution, like early slackware and now CRUX to get started. after reading coreboot pages, getting coreboot, filo and flashrom sources from git, configuring and … [View More]

one rom image for two boards?
by Gerd Hoffmann 07 Jun '13

07 Jun '13

Hi, Is it possible to build a single rom which is able to run on two different boards? Background: qemu recently got an emulation for a more recent chipset. Current seabios roms detect at runtime whenever runs on the old (i440fx + piix4) or the new (q35 + ich9) and initializes the hardware accordingly. I'd like to do the same with coreboot if possible. Drivers seem to be kicked by hardware detection (struct pci_driver), so it looks like simply compiling in two southbridges could work. … [View More]

About the status of "Getting Started : QEMU"
by Svetoslav Trochev 07 Jun '13

07 Jun '13

Hi Everyone, I was looking at the wiki's Getting Started | QEMU section [1] and I noticed that all examples are outdated: coreboot V2 or V3. I understand that for most coreboot developers QEMU will provide no benefits, but for me it seem a good idea to practice building coreboot for QEMU in order to gain better understanding about coreboot before I start working with hardware. So my question is: Why listed examples are out of date? Is it because there is no much of benefit to play with QEMU/… [View More]

The microcode is like a "firmware" sent to the CPU. we don't think it's code but we don't really know.

On the X201 there are full versions of that, on the chromebooks there are light versions, but we don't know what theses light version do. > Again, can google control my laptop with this code?

The > X60[s] and T60[p] made no mention of proprietary code. :) Can anyone > confirm this? That would be pretty sweet! Theses have microcode. Prefer the X60[s] for now because it has native graphic initialization that will be submited for review really soon. The T60 is very similar though, so once the code will be submited, and if you're skilled enough you could port that code to the T60. Note that some T60 have an ATI graphic card, that won't work with the native graphics initialization becasue it's made for intel GPUs. Currently native graphics initialization gives graphics in grub as a payload. Peter Stuge has code on top of my code and I'm waiting for him to submit it. Then I'll test it even more but I was able to load parabola and trisquel distributions trough this method... Without native graphics init or the non-free option rom(which the native graphics init tries to replace) you will have no graphics during boot and probably some memory corruption issues with lastest parabola kernels. also nvramtool will need an extra parameter to work and cbmem -c will not work. Parabola is based on arch, Trisquel is based on ubuntu, both are 100% free software. > > The Lenovo X201 supports a faster cpu, but the status links to a page > that says it has proprietary components too...anyone know anything > about these proprietary components?

My goal is to build a laptop > that is 100% free of proprietary code... Right now there are some options: *) The Lemote netbook(not the notebook which has an ATI option rom). *) The Lenovo X60 *) The Lenovo T60 If you also plan to run a 100% free distribution on the Lenovo X60 or T60, you will probably need an internal or external wifi card that is not intel(because it requires a non-free firmware). Thinkpenguin sells some ( https://www.thinkpenguin.com/ ) that are supported by 100% free software. Also you probably want the dock for having serial(that's where coreboot logs are sent). it's the best way to get logs. The other way that would work is spkmodem, which only require an audio cable, however it's way slower, is receive only and only works in coreboot and grub2. cbmem is not a really good way to obtain reliable logs because: * it require a booted computer(up to grub or GNU/Linux). * it truncate logs when writing is slower than the flow of execution...
