To: freebsd-current@freefall.cdrom.com (FreeBSD Current), freebsd-ports@freefall.cdrom.com Date: Sat, 4 Mar 1995 17:34:04 -0800 (PST) X-Mailer: ELM [version 2.4 PL24] Content-Type: text Content-Length: 1713 Sender: current-owner@FreeBSD.org Precedence: bulk I upgraded my 486DX66 EISA system from 8MB to 24MB of RAM, but I can't tell if the system ``knows'' about all the memory. I looked at the output from `dmesg', `top', and `systat -vmstat'. Dmesg and systat appear to report that 24 MB are present, but top seems to be missing 8MB. So, how does one determine if ALL the memory is being utilitized? Does top contain a bug that makes the system appear to be limited to the ISA 16 MB boundary. %dmesg FreeBSD 2.1.0-Development #0: Wed Mar 1 09:06:05 PST 1995 root@troutmask.apl.washington.edu:/usr/src/sys/compile/TROUTMASK CPU: i486DX (486-class CPU) Origin = "GenuineIntel" Id = 0x435 This is an i486DX2 Stepping=5 Features=0x3 FPU VME real memory = 24772608 (6048 pages) avail memory = 23425024 (5719 pages) %top load averages: 1.56, 1.03, 0.52 17:24:36 30 processes: 2 running, 27 sleeping, 1 zombie Cpu states: 65.0% user, 0.0% nice, 23.2% system, 1.4% interrupt, 10.4% idle Memory: 15M Act 2384K Inact 2732K Wired 472K Free 6% Swap %systat -vmstat 4 users Load 1.31 1.12 0.64 Sat Mar 4 17:27 Mem:KB REAL VIRTUAL VN PAGER SWAP PAGER Interrupts Tot Share Tot Share Free in out in out 305 total Act 7764 1124 50028 36908 2800 count 100 clk0 irq All 23468 9504 679420 648300 pages 128 rtc0 irq -- Steven G.
