This may have been asked before, but .. One of our clients wants to use PC-NFS next to a rather memory demanding application. The two don't fit in memory together even in a barebone stripped system. The book says "PCNFS.SYS is approximately 75 KB (after allocating buffer and cache structures)" We discovered tha PC-NFS allocates buffers for drives D - V, where our client needs only drive D. Can we tell PC-NFS not to claim that many buffers and how much memory can we gain this way -- Guus van der Wal Computing Centre Delft University of Technology, The Netherlands USEnet: rcdswal@dutrun.tudelft.nl BITnet: rcdswal@hdetud1.bitnet

Not true. PC-NFS tells DOS that it is a block device handling units D to V, but it doesn't allocate any buffers for these drives. It includes certain internal data structures for 8 drives, but this space is hard-coded and cannot be reconfigured. It also includes a number of buffers, but the number is not configurable. #.... where #our client needs only drive D. Specifying LASTDRIVE=D will save a little space in DOS, which uses this to determine how much space to allocate for the logical drive table. You can also free up some space in PC-NFS by telling it that not to reserve space for file locks or IP fragment reassembly buffers. (Assuming you don't need them, of course!) This is all documented under "Customizing PC-NFS" in the manual. -- Geoff Arnold, PC-NFS architect, Sun Microsystems.

What we do here at SJRPP is run QEMM Loadhi.

This pc is an AST Premium 386 with an Artist 12GT vidio board running ACAD R10.
After loading the drivers Norton SI reports 99 kbytes used, 541 kbytes available.
CHKDSK reports 533968 bytes free.
I can shell out of ACAD and run just about anything!!!
