+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.
