- Subject: 3b2 procedure to raise MAXMEM
-
- Below is the procedure I followed to allow enough memory for GnuEmacs to run
- on my 3b2/400. The end result of this is that a process can snarf up to 2Mb
- of memory. This can be a bit dangerous on a 2Mb machine, but I tried it and
- it worked ok.

-
- In the simplest case, these are the procedures to reconfigure a 3bx kernel.
-
-
-
- 1] cd /etc/master.d
-
- `ls` shows the files to be:
-
- README ctc* hdelog idisk ipc iuart kernel mau
- mem msg ports* prf sem shm stubs sxt
- sys xt
-
- 2] Edit the file which contains the parameter[s] you wish to change.
- In the following excerpt from /etc/master.d/kernel the value MAXMEM
- was raised from 256 to 1024.
-
- In V.3.0 and later releases, the parameter in question is MAXUMEM
- instead of MAXMEM.
-
-
- *
- * The following entries form the tunable parameter table.
- *
-
-
- NCALL = 30
- NPROC = 60
- NTEXT = 58
- NCLIST = 188
- * maxmem is number of pages (2K) was 256 --dmk
- MAXMEM = 1024
- MAXUP = 25
- * hashbuf must be a power of 2
- NHBUF = 128
- NPBUF = 8
-
- 3] cd /boot
-
- 4] mkboot -k KERNEL
-
- 5] shutdown -i5 -g0 -y
-
- This will take the machine down and bring it back up into firmware
- mode. When you see that the machine has reached this state, type the
- firmware password (default=mcp). The machine will ask for the name of
- a program to execute. At this prompt enter /etc/system . The machine
- should start to boot and display its configuration data.

- I do not feel that having the default firmware password is a
- problem... but if you wish to edit it out, feel free.
