There is no mention of changing the tunable parameters using the ktune command when you change the configuration of memory in your UNIX PC. This is unlike the 3B2 line where you are instructed to modify the /etc/master.d/kernel file and adjust the tunable parameters according to their "chart" of memory configurations. The chart in the manual AT&T UNIX PC UNIX System V User's Manual Volume I, under ktune(7) says: --------------------------------------- parameter Minimum value Default --------------------------------------- nbuf 25 100 ninode 80 400 nfile 80 300 nproc 30 100 ntext 24 75 nclist 32 150 npbuf 4 16 ncall 16 32 nttyhog 0 1024 The manual states that if you change these values to "unusable" ones for your memory configuration, the UNIX PC will changes these (either increase or decrease, accordingly) depending on your memory configuration during bootup sanity checking. Basically that means you can't mess them up and get a unbootable /unix. If someone can suggest changes to these for different memory configurations from 2MB to 4MB in .5MB increments this will be very useful! -Lenny -- US MAIL : Lenny Tropiano, ICUS Computer Group IIIII CCC U U SSS PO Box 1 I C U U S Islip Terrace, New York 11752 I C U U SS PHONE : (516) 968-8576 [H] (516) 582-5525 [W] I C U U S TELEX : 154232428 [ICUS] IIIII CCC UUU SSS AT&T MAIL: ...attmail!icus!lenny UUCP : ...{mtune, ihnp4, boulder, talcott, sbcs, bc-cis}!icus!lenny
