Hello: Using top, I found that the 128MB of ram we have in our machine was not being used. Only about 64MB is being seen by BSD. I found a faq on bsd.org that said that the kernel needs to be told explicitly how much ram there is in the machine. The faq suggested to channge MYKERNEL config file by adding this line. "options "MAXMEM=<n>" Where n is your memory in Kilobytes. For a 128 MB machine, you'd want to use 131072." After adding this line, my make came back with this error: cc -c -O -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -nostdinc -I- -I. -I../.. -I/usr/include -DAPM_BROKEN_STATCLOCK -DFAILSAFE -DCOMPAT_43 -DCD9660 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL ../../i386/i386/machdep.c ../../i386/i386/machdep.c: In function `init386': ../../i386/i386/machdep.c:1157: parse error before `<' *** Error code 1 If I take out the line, if makes fine. Any help with this would really be apreciated.
