I presume the new one is similar to my original driver. OS-9 can handle 128 MB 
max if you use a cluster size of 1 sector (256 bytes/sector). If you increase 
the cluster size, you can get up to 4 GB (although, some software was hardcoded 
for 1 sector clusters, so you need to be careful about what utilities you run). 
If you add partitions to the mix, you can make several of up to 4 GB each (I 
tested mine with 5 descriptors of 4GB each on a 10 GB Seagate drive when I wrote 
the original driver). The idea of using offsets (to point to the start of each 
partition) was taken from Bruce Isted’s driver from back in the Eliminator days.

the way the spec for the ide explained it. You eventually run out of room for 
tables, but this is an experiment, so who cares. I'll just do it again until I 
find something I like.
