- Convert dpt_pci.c to newbus.
- Add support for ISA based DPT adapters (this doesn't quite work yet).
- Sync dpt_eisa.c with my local copy.
- Simplify how EISA IDs are matched.
- Prototype.
- Formatting nits.
- Conform to how I do things in dpt_pci.c/dpt_isa.c.
- Modify dpt_scsi.c:dpt_alloc() to DTRT with newbus.
- Add some comments to dpt_scsi.c:dpt_pio_get_conf().
- Add additional check to dpt_scsi.c:dpt_get_conf().
- Add some useful error messages to dpt_scsi.c:dpt_init().
