please check your AutoConfig.kmk. I assume it contains

  VBOX_WITH_OPEN_WATCOM :=

If your build environment does not contain the Watcom C compiler,
the alternative BIOS source file is used, see

  src/VBox/Devices/PC/BIOS/VBoxBiosAlternative.asm

To use the C files, install the Open Watcom C compiler, see

  http://www.openwatcom.org/

Then rerun the configure script and make sure it finds the compiler
and sets VBOX_WITH_OPEN_WATCOM properly.

Kind regards,

Frank
