Without this bugfix, the resource for the PCI/ISA video memory at 0xa0000 - 0xbffff is too big, i.e. it goes up to 0xcffff instead of just 0xbffff as it should. Here's the diff from two runs of the tool from http://www.linuxbios.org/pipermail/linuxbios/2007-June/022449.html on the MSI MS-7260 (K9N Neo), with and without the bugfix. After applying, the resource size is correct again. --- dumpres_lb_pci_vgacard_without_resfix.txt +++ dumpres_lb_pci_vgacard_with_resfix.txt @@ -11,7 +11,7 @@ MMIO map: #2 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 MMIO map: #3 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 MMIO map: #4 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 -MMIO map: #5 0x00000a0000 - 0x00000cffff Access: R/W Dstnode:0 DstLink 0 +MMIO map: #5 0x00000a0000 - 0x00000bffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #6 0x00fc000000 - 0x00fd1fffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #7 0x00fd200000 - 0x00fd1fffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #0 0x000000 - 0x003fff Access: R/W ISA VGA Dstnode:0 DstLink 0 Signed-off-by: Rudolf Marek <r.marek@assembler.cz> Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2853 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 |

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