I looked at the official x86emu code at ftp://ftp.scitechsoft.com/devel/x86emu/x86emu-0.8.tar.gz This contains something pretty similar than what we need in the v86bios directory. It's a bios emulation that either plugs into vm86 or x86emu. > Looking at the size I got the x86emu emulation including an incomplete > legacy bios emulation plus userland pci code (testbios) to > below 150k with -Os, so it would fit in a 256k rom with linuxbios and > etherboot pretty easily. On x86 most of the code can be dropped leaving > probably less than 32k for the legacy emulation. compiling v86bios.vm86 from above I get everything into 20k.
