    I'm getting so many errors when trying to this, I don't even know where to start reporting :(

    My host is now filled up with masses of useless non-working files, patches and downloads and results from partially running scripts, giving even more funny errors when trying to compile anything and i got no clue what to delete.

    I tried all the ways i could find on mdw, and none was even close to working. Is there any downloadable ready and current bios file?

    @ lustich, get yourself proper Linux development environment & you will have no errors. It is not really complicated to compile seabios

    And this is wrong section, there is already sticky about the subject in Virtualization

    Hi,

    little question :D

    Can you tell me what exactly to change in patch.sh ?
    What to delete and what to add?

    Thanks in advance!

    jackdany,

    Pull the SLIC tables from post forums.mydigitallife.net/threads/5952-Win-7-amp-Server-08-R2-SLIC-2-1-Bin-Collection [moderator: please fix URL], and change the /sys/firmware directory to the SLIC blob from the file.

    See a diff:

    Code:

    Build your BIOS, load your VM with it and register it with the "Windows 7 Repository". Worked like a charm to me.

    Good luck.

    Lustich,

    Followed line by line and it just worked. Glad that the links are not broken, even after a year.

    Anyone got this working recently on Ubuntu 14.04?
    Somehow, the BIOS loaded is not reflected in guest VM

    thanks, Tito.

    Your signature has two well informed posts. But I still not getting it. For win7 dell machine, there is only SLIC, not MSDM table. Also, is bios.bin is still required? tried qemu 2.0, with SLIC dumped. Somehow it didn't work.

    SeaBIOS 1.9.0
    ==========
    Available on 20151117. Major changes in this release:
    The default boot menu key is now the ESC key (instead of F12)
    Initial support for Trusted Platform Module (TPM) hardware and BIOS calls
    Initial support for chain loading SeaBIOS from Grub (via multiboot support)
    Initial support for booting from SD cards on real hardware
    virtio 1.0 device support
    The build will no longer include the build hostname or build time on "clean" builds. This makes the build binaries more "reproducible".
    Basic support for running SeaBIOS on Baytrail Chromebooks
    SeaVGABIOS improvements: Improved support for old versions of x86emu (the "leal" instruction is now emulated)

    Several bug fixes and code cleanups


    SeaBIOS 1.8.0
    ==========
    Available on 20150218. Major changes in this release:
    Several USB timing fixes for USB controllers on real hardware
    Initial support for USB3 hubs
    Initial support for SD cards (on QEMU only)
    Initial support for transitioning to 32bit mode using SMIs (on QEMU TCG only)
    SeaVGABIOS improvements Added cursor emulation to coreboot native init vgabios (cbvga)
    Added support for read character calls when in graphics mode

    Developer documentation added to "docs/" directory in the code repository and several documentation updates
    Several bug fixes and code cleanups

    As of the 1.8.0 release, new feature releases will modify the first two release numbers (eg, 1.8) and stable releases will use three numbers (eg, 1.8.1). The prior behavior of using a forth number (eg, 1.7.5.1) for stable releases will no longer be used.



    Any new patch for SEABIOS 1.9.0 ?

    How can we make it permanent for all VM,
    does KVM and other seabios base Linux hypervisors have a default config file for all VMs, we can modify.

    Thanks.

    No, you do it for each VM
