In their infinite wisdom, Digital Research made 2.x is 2 sectors larger than 1.4, leaving only 7 sectors for the BIOS. California Computer System's solution was to put a stripped BIOS on the system tracks, and hack the command processor so that it attempts to execute RLOCBIOS.COM when first booted. RLOCBIOS then finds the current BIOS and overwrites it with a bigger one. I think this method is gross in the extreme and would like to find a better way. For example, I could use an interactive bootstrap like the one most Unix systems have. It understands filesystem structure, allowing me to boot in any executable file on the disk by name (e.g., "unix", "testunix", etc).
