Remaining to be done: PIRQ table MP table ACPI table relocate the GDT reload to a sensible place -- or figure out if we even need to bother; we're back to execute in place and the GDT is in flash rom ==> we can leave it until we boot the payload I think. At this point, however, we've got the basic bits to sensibly create tables. This has been tested and works on bochs. It is working to a point, but still failing on qemu for reasons we don't quite understand.

------------------------------------------------------------------------------- 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.
