In reading thru the documentation available on Bios Parameter Blocks, I tried to get around the 32Meg drive limit by makeing the sectors larger (2048). What I ran into was that DOS refused to use the driver and complained about "Invalid Sector Size in C:\SCSI.SYS". It turns our that you cannot have a loadable driver that defines a sector size larger than the largest sector size used by the internal/resident drivers. Now for the question. Does anyone know of a way to convince DOS to allow the larger sector sizes? It might be possible to create a boot floppy with large sectors, but I don't want to have to boot from a floppy all the time. Help!?!?!?!?
