No. BIOS does not guarantee that the ROM 8x8 bold character set is
stored at 0xffa6e.  It's at wherever the int 0x43 vector says it is.

They're stored elsewhere in ROM; a pointer to them is in the int 0x1f
vector.  Ralf Brown's interrupt list gives the answer:
  int 0x43 and int 0x1f at  http://www.ctyme.com/rbrown.htm
