Solution

  • The standard PC BIOS has no runtime APIs for network communication.

    Pretty much the only networking code you find in a BIOS is the PXE boot loader, which provides a pre-boot environment for downloading a kernel from a network server and executing it. This does not provide any post-boot runtime services though.

    If you want to do network communication while you are running from disk, you need to implement your own networking stack.
