codepager is simple dumper for the 0x00-0xFF character symbols. Simply assemble the code, then drop the binary on a floppy or a flash drive and boot from it. This will give you the codepage depictions on your particular setup in a mildly organized manor. Quite useful for debugging, or just to cure your curiousity.
Assemble it, or use the pre-built image, then put it on a floppy or a flash drive, and boot from it.
