The baseline EPROM would be useful for new builders trying to validate the primary functions of the SBC. It would be interesting the checksum the EPROM and assure the EPROM interfaces are functioning properly. It is possible for the first section of the EPROM to appear to be working but at progressively higher addresses, there is the possibility of mirrored disfunction. A memory test would be a good idea to assure the RAM address and data lines are working well.

The most useful aspect of the UBIOS right now is the SCSI2IDE target. This allows the firmware to be built using SDCC with only a minimum part in assembler, and the main in ANSI C. There is also a preliminary build for the N8 and the baseline (SBC V2) but those aren't ready for prime time yet.
