Dear SeaBIOS folks,
It was announced already on the coreboot mailing list , so some might already know this.
redsPL got SeaBIOS and a Win 3.1 (floppy disk) (with coreboot) booting .
Because the standard coreboot payload with SeaBIOS only occupies only about 1MB out of the full 8 on the ROM, I thought about embedding a full OS on the remaining 7 megs. It turns out that SeaBIOS has partial support for booting from flash - it sets up a virtual floppy drive with your floppy of choice loaded from floppyimg/<name>.lzma, but this gives us at best 2.88MB (standard ED floppy disk size, exactly 2x as large as a popular 1.44M), and I wanted more.
I guess it should be reproducible in QEMU too.
