#95: Run coreboot in VirtualBox ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: defect | Status: new Priority: minor | Milestone: Component: misc | Version: Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ It would be nice if we could test coreboot images in VirtualBox, see http://virtualbox.org/. VirtualBox does not (yet) provide a simple mechanism to use a different BIOS in their emulated machines (something like "-L" in qemu). Instead the BIOS image (a custom bochs BIOS + LGPL'g VGABIOS) is converted to C code (an array of bytes, or the like) and merged into the VirtualBox executable. The relevant files are {{{ src/VBox/Devices/PC/DevPcBios.cpp bldprogs/bin2c.c }}} if someone want to hack VirtualBox to easily support using coreboot images instead of their usual BIOS. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/95> coreboot <http://www.coreboot.org/>

Hello, as I posted on the blog of Uwe, I have a sony vaio pcg sr1k laptop, and wonder if I could flash it with coreboot. The box has Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge chipset. hovewer the results of the following commands are not encouriging, please tell me if there is any chance to get coreboot working. Please find attached the outpoot of the commands. sudo superiotool -dV > siot.out lspci -tvnn > lspci.out sudo flashrom -V

[LinuxBIOS] Add initial support for intel i855gme northbridge
by Jon Dufresne Jan. 20, 2009

Jan. 20, 2009

Add initial support for i855gme. This is a work in progress and I don't expect it to work on all boards, or even any besides mine. This is based heavily on i855pm. Signed off by Jon Dufresne <jon.dufresne(a)gmail.com>

[LinuxBIOS] A8N5X port
by Robert Millan Nov. 21, 2008

Nov. 21, 2008

This patch includes config files for the asus/a8n5x port. It is the same as asus/a8n_e with a different pnp layout, so I used #include's whenever possible. System boots and is usable with usb keyboard. works: - serial port - vga (old pci card) - memtest86+ succeeds, but only with Rudolf's patch for unbuffered dimms in K8. Otherwise you get spurious memory corruption. - ide disk - usb doesn't: - ps/2 keyboard - onboard ethernet - vga pci-e card (??) - any other pci card I tried wasn't tested: - sata - game port - onboard audio (not supported by alsa anyway) - ps/2 mouse -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak? (as seen on /.)

LZMA magic number
by Myles Watson Sept. 30, 2008

Sept. 30, 2008

Is there a magic number for LZMA? Should there be? I accidentally used an uncompressed payload with v2 when it expected a compressed payload, and it gave me the message: Decoder scratchpad too small!! Decoding error = 1 I think it would be nicer to have an error like: Payload not compressed with lzma! Myles

[PATCH] [RFC] v3: CS5536 cleanup
by Carl-Daniel Hailfinger Aug. 18, 2008

Aug. 18, 2008

Clean up Geode companion chip CS5536 code and improve VPCI hiding debug message. This also eliminates a few dev_find_pci_device(). I'm not happy with the new code yet. hide_vpci() should have a variant which takes a struct device *.
