The 1.9.0 version of SeaBIOS has now been released. For more information on the release, please see:
New 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
