I was refered to the man page in the z0magic patch file and I snarfed
the following text from the network mods. I put in a few comments about
the Vax and RT differences. I still believe the 2048/1024 discrepencies
in the rest of the man page should eventually be reconciled. As the man
pages are are being maintained in the system dependent man directories,
I believe on installation, the proper 1024/2048 swaps should be made.
