OK, so we have (these require the OS to support them, of course).
1) use inline assembly code
2) use graphics mode, and draw out the name.
3) use a graphics library
4) poke directly into video memory, as you could with DOS
5) use an API to write it out
6) use a system call, to do it.
And my idea's:
6) call a bat file, and have it print out the name
7) use pipes, to output it >
8) use ASCII style art, to write out the letters (letters would be larger than normal char's, but readable.
Seems like a pretty resourceful list, in total.
