Thanks for the enlightenment!
I did notice before that ./configure says "Open Watcom was not found" but
I thought it was OK to ignore it. (my big mistake! >.< )
I also read in the configure file that OpenWatcom compiler is needed for
compiling the BIOS (which just reassures my mistake)
Followed the link and compiled and installed OpenWatcom and changes to
system.c already take effect!
