[comp.sys.amiga.tech] GVP drives: How much memory space?

black@rpi.edu (Jerry Glomph Black) (11/14/89)

When I boot my 1MB A500 off the usual WB1.3 floppy, I end up with 900k or
so memory available.
When I boot up my 46 MB GVP hard drive, another 150k disappears!  It is in
two partitions, set up for BUFFERS=30, so I might expect to lose 50k, not
150k, by virtue of the drive's existence.  What's going on??
