What's going on here? I added another 4 MB memory to my Mac II, for
a total of 8. I booted A/UX, and got the (reassuring) numbers
total memory size 8388608 bytes
available memory 7012352 bytes
Then I went in to "tune" the kernel parameters and used kconfig -n /unix
to set the following:
NBUF=2500
NINODE=600
NFILE=400
Upon rebooting, available memory dropped to 4382720. I did a pstat
and got "System name list out of date". I heard about the pstat bug,
so I dropped NBUF to 999. Now available memory was 6000640. When I
reduced NINODE to 200 and NFILE to 200, I got 6078464 available.
Can anyone explain what's going on? If anyone with 8 MB of memory has
a good set of kernel parameters, could he/she email it to me?
