- Implement a simple PIO driven function for retreiving the onboard
configuration information from a DPT card at a given port. This is needed by the ISA bus front end (still to come) and the EISA bus front end (which hasn't ever worked). - Blow away dpt_eisa.h as the information it contains does not justify an additional file. - Convert dpt_eisa.c to use the onboard config instead of trying to read the EISA configuration registers.
