- makes sprintf work, in a re-entrant way - gets rid of a lot of ugly debug stuff (thanks for the Kconfig log level stuff guys!) - boots like a bat out of hell on qemu :-) The changes are trivial, I am self-acking. To run this under qemu, I do this: cp LinuxBIOSv3/build/linuxbios.rom bios.bin ; qemu -nographic -L . -kernel linux-2.6.15-bochs/vmlinux -hdc hda -hda hda | tee out 2>&1 here is the output from a run. Note that cpu's still don't have a path of any kind, and that show_all_devs is not working right. But we're getting there. I think I'll next try to really boot a linux with a hard drive, and see how it goes. LinuxBIOS-3.0.0- Tue Mar 6 18:41:59 MST 2007 starting...

------------------------------------------------------------------------------- LinuxBIOS README ------------------------------------------------------------------------------- LinuxBIOS is a Free Software project aimed at replacing the proprietary BIOS you can find in most of today's computers. It performs just a little bit of hardware initialization and then executes one of many possible payloads, e.g. a Linux kernel. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by LinuxBIOS. Examples include: * A Linux kernel * FILO (a simple bootloader with filesystem support) * GRUB2 (a free bootloader; support is in development) * OpenBIOS (a free IEEE1275-1994 Open Firmware implementation) * Open Firmware (a free IEEE1275-1994 Open Firmware implementation) * SmartFirmware (a free IEEE1275-1994 Open Firmware implementation) * GNUFI (a free, UEFI-compatible firmware) * Etherboot (for network booting and booting from raw IDE or FILO) * ADLO (for booting Windows 2000 or OpenBSD) * Plan 9 (a distributed operating system) * memtest86 (for testing your RAM) Supported Hardware ------------------ LinuxBIOS supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.linuxbios.org/Supported_Motherboards * http://www.linuxbios.org/Supported_Chipsets_and_Devices Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the LinuxBIOS website: http://www.linuxbios.org You can contact us directly on the LinuxBIOS mailing list: http://www.linuxbios.org/Mailinglist Copyright and License --------------------- The copyright on LinuxBIOS is owned by quite a large number of individual developers and companies. Please check the individual source files for details. LinuxBIOS is licensed under the terms of the GNU General Public License (GPL). Some files are licensed under the "GPL (version 2, or any later version)", and some files (mostly those derived from the Linux kernel) are licensed under the "GPL, version 2". For some parts, which were derived from other projects, other (GPL-compatible) licenses may apply. Please check the individual source files for details. This makes the resulting LinuxBIOS images licensed under the GPL, version 2.
