Hi guys I don't know how usefull is it but there is a bug in cache_as_ram.inc and cache_as_ram_post.c for the 6fx intel processors. The code disable / enable the prefetcher in IA32_MISC_ENABLES MSR register. cache_as_ram.inc : /* Disable prefetchers */ movl $0x01a0, %eax rdmsr orl $((1 << 9) | (1 << 19)), %eax orl $((1 << 5) | (1 << 7)), %edx wrmsr should be movl $0x01a0, %ecx Same thing in cache_as_ram_post.c /* Enable prefetchers */ "movl $0x01a0, %eax\n" "rdmsr\n" "andl $~((1 << 9) | (1 << 19)), %eax\n" "andl $~((1 << 5) | (1 << 7)), %edx\n" "wrmsr\n" should be "movl $0x01a0, %ecx\n" Regards, Thomas

EP80579 Mainboard support
by Arnaud Maye 25 Jun '09

25 Jun '09

Hello Everyone, We are designing a mainboard powered by an EP80579 and I came across coreboot. I've seen corebot v2 supports the Truxton EP80579 Development kit. However I cannot get any relevant information about Truxton. Is this the "official" intel development kit (EP80579TRXDK) or something else? I wanted to order the exact board coreboot supports and use this as a reference design. Could the people in charge of maintaining the EP80579 modules get back to me with this information? The initial stage would be to have Windows/Linux running on our board followed by VxWorks. Anyone around here as already used coreboot to "boot" a Vxworks system? Thank you!

LinuxTag 2009 in Berlin, June 24-27
by Peter Stuge 03 Jun '09

03 Jun '09

Hello, I am happy to announce that coreboot will be exhibiting at LinuxTag in Berlin again this year, following up on our presence there in 2007 and 2008. http://www.linuxtag.org/2009/ If you have any ideas about something fun that we haven't tried at a booth before, or if there is something in particular that you would like to see, and of course certainly if there is something that you would like to prepare yourself, I would love to hear about it! If you have experience from our booths in the past maybe you can comment on what must be improved this time? Everyone who has a chance to make it to Berlin should make sure to come check the expo out! LinuxTag is a fantastic opportunity to meet others who are active in or interested in open source software. Lots of fun! :) //Peter

SeaBIOS, serial output, and grub
by Ward Vandewege 22 May '09

22 May '09

I've been experimenting with SeaBIOS, and I like what I'm seeing a lot. Great work Kevin! I think I found one bug, and I have a feature request. Feature request: I'd really like a serial console for SeaBIOS. I 'd like serial to just mirror the VGA console so that either could be used for viewing and input. Right now, it seems only sending debug output to the console is supported. Bug: I have grub configured to pause 5 seconds while giving the user to select either serial or VGA console for input. This is done with these lines in menu.lst: serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 terminal --timeout=5 serial console This does not appear to go over well. The symptoms I see are: a) the 'Press any key to continue' is only printed on the VGA console, not on serial b) it takes way more than 1 second between the 'Press any key to continue' lines - presumably because writing to serial is somehow failing c) while this is happening, keyboard nor serial console input works If I press enough keys before I get to grub and/or during this serial/console detection, I can sometimes get it to show the menu on the VGA console (it defaults to serial). If I get to that point, the keyboard usually works just fine. Also, the keyboard works fine before I get to grub, but it's hard to catch the F12 keypress as everything goes pretty fast. I've tried with and without CONFIG_DEBUG_SERIAL set in src/config.h. It does not seem to make a difference. CONFIG_SERIAL is set to 1. Suggestions?
