- We are busy making an MS-DOS5 bootable floppy that starts PC-NFS4.0a
- with a >minimal size< of the bootflop. Maybe someone is interested in
- the same thing, then we could share ideas. If I get enough response that
- is not posted to the net, I'll post a summary.
-
- The reason why we want a minimally-sized bootflop, is that we have a
- classroom of PC/XT's with only 640kb memory, that boot from a (Dirk
- K\"oppen) boot-ROM. A minimally-sized bootflop is needed, since the
- image of the flop is downloaded as a RAM-disk, and one needs to have
- some memory left to start PC-NFS.
-
- These PC's now use the boot-ROM to get MS-DOS5 and PC-NFS3.0.1, and the main
- methods to make it work were:
- - delete all non-necessary files
- - compress (with PKLITE) most of the .COM and .EXE files
- - use a 306kb full, 34-track (instead of 40-track) formatted floppy.
-
- We have an MS-DOS5 PC-NFS4.0a bootflop that works for starting PC-NFS, but
- it is still too large, and some of the methods used are not great.
- Below I will describe the contents of the flop in detail,
- but first my questions:
-
- 1) Is there some way to get rid of RNMFILE.EXE? All hostname <-> address
- info comes from NIS in our case, so I could do without RNMFILE.EXE.
- Simply deleting it, or my guess at adjusting NETCONF results in a
- flop that can't start PC-NFS anymore.
-
- 2) Does anybody have any ideas to make PCNFS.MSG less than 37680 bytes?
- We deleted PCNFS.MSG from the floppy, and start PC-NFS using
- 'net -q init'. After we mount an NFS-drive, we point NFSPATH to
- a full directory (e.g. containing PCNFS.MSG). Of course, if we do not
- use the '-q' the first messages look bad ("PC-NFS message #???").
- The best solution for us probably would be a small PCNFS.MSG (only
- messages related to the first actions).
-
- 3) We are going to try to cut the last track(s) off the RAM-disk after
- CONFIG.SYS has been read (PCNFS.SYS could be on the last tracks, e.g.).
- Thereby some memory occupied by the RAM-disk would be released.
- If this works there will be ample memory for starting PC-NFS, the only
- goal then is to get a nice, working, 360kb PC-NFS4 bootflop.
-
- 4) Anybody have any more/better ideas?

- Read below for a detailed description of our current PC-NFS4.0a MS-DOS5 flop
-
-
- The current size of the bootflop is approximately:
- 362496 bytes total disk space
- 71680 bytes in 2 hidden files
- 2048 bytes in 2 directories
- 269312 bytes in 18 user files
- 19456 bytes available on disk
- 1024 bytes in each allocation unit
- 354 total allocation units on disk
- 19 available allocation units on disk
-
- File/dir contens of the flop: (with sizes in bytes)
- 293 autoexec.bat
- 222 config.sys

-
- The following files were compressed with PKLITE: net.exe prt.com command.com
- This helps a lot:
- net.exe: 110364 --> 62273 bytes
- command.com: 47845 --> 30976 bytes
- prt.com: 5436 --> 2975 bytes
