bayou 0.2
by Jordan Crouse 27 May '08

27 May '08

I've posted a updated tarball for the bayou chooser: http://coreboot.org/~jcrouse/bayou_0.2.tar.gz This version has been updated to use the PAYLOAD_PARAMs options from the payload, so it is prettier. This requires the patches I just sent for libpayload. I've also uploaded a demo ROM for qemu: http://coreboot.org/~jcrouse/bayou-demo-2.rom Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc.

Hello, I know Carl-Daniel had a few questions recently about logos.... What I think, would be a great promo for coreboot booths at shows is a "powered by coreboot" logo small enough to fit on a "case badge" that could be handed out. We could also use this "powered by" logo for websites that have webservers running coreboot etc. What do you think? -- Thanks, Joseph Smith Set-Top-Linux www.settoplinux.org

buildrom

buildrom wants to set up v3 for dbe61 but not 62? Did 61 suddenly get supported and I missed it :-) I'm really just trying to build etherboot that works ... ron

Hi, if you know of any cool features in coreboot, flashrom, buildrom, libpayload, coreinfo etc., please list them in response to this mail. Since I'm working almost exclusively on v3 and flashrom, I'm bound to miss the exciting news/features in other areas, so please help me out. Exciting coreboot features are: 1. Almost every (free) operating system can be used as a payload in ROM 2. Having an OS in ROM means it works even if HDD/UDB/NIC are broken 3. Logging in with SSH is possible regardless of the brokenness of local storage if the payload has a SSH server or can load one via network 4. Security against viruses/malware: If write protection for the ROM is active (and can't be circumvented), the OS in ROM can't be compromised 5. Improved diagnostics: We don't rely on the usual cryptic and uninformative beep codes, but output meaningful english error and debug messages via the serial port 6. Error and status messages are saved in RAM (v3 only) and can be read by the OS during or after boot with a dmesg-like mechanism 7. Extemely high speed: We have a record of ~600 ms from poweron to bootloader, which is in stark contrast to the 10-30 seconds for proprietary BIOS 8. Anything supported by the hardware can be supported by coreboot: Some universities use the second processor socket of a dual processor board for a FPGA instead f a processor 9. The code is written almost completely in C with ~100 lines assembly remaining per architecture, compared to pure assembly for proprietary BIOS 10. Recompilation of the whole firmware with arbitrary features takes 10-30 seconds (v3 only) 11. You decide which features (EFI/OpenFirmware/BIOS/etc) you want, the vendor can't limit you Exciting flashrom features are: 1. No reboot needed for BIOS update 2. No DOS/Windows needed for BIOS update 3. Cross-flashing is possible 4. Hot-flashing is possible Regards, Carl-Daniel

Dear coreboot readers! This is the automated build check service of coreboot. The developer "mraudsepp" checked in revision 3350 to the coreboot source repository and caused the following changes: Change Log: Mark SST49LF004A/B as tested (trivial). Tested by me on actual hardware (all operations) - Artec Group DBE62 with SST 49LF004B Signed-off-by: Mart Raudsepp <mart.raudsepp(a)artecdesign.ee> Acked-by: Mart Raudsepp <mart.raudsepp(a)artecdesign.ee> Build Log: Compilation of via:epia-cn is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=3350&device=epia-cn&vendor… If something broke during this checkin please be a pain in mraudsepp's neck until the issue is fixed. If this issue is not fixed within 24h the revision should be backed out. Best regards, coreboot automatic build system
