I just tested the minimum memory requirements for FreeBSD 6.1-RELEASE through 2.2.9-RELEASE using VMware 5 Workstation: FreeBSD 6.1-RELEASE: 4MB, 8MB: Dies at bootstrap loader. 12MB, 16MB: Dies while loading acpi.ko. 20MB: Boots / Successfully installed the default minimal distribution set. Mem: 2484K Active, 1396K Iact, 6004K Wired, 680K Cache, 1984K Buf, 348K Free Swap: 7184K Total, 2732K Used, 4452K Free, 38% Inuse FreeBSD 5.5-RELEASE: 4MB, 8MB: Dies at bootstrap loader. 12MB, 16MB: Dies while loading acpi.ko. 20MB: Boots / Sysinstall dies after writing filesystem information. 24MB: Boots / Successfully installed the default minimal distribution set. Mem: 2332K Active, 1196K Iact, 9468K Wired, 1136K Cache, 3008K Buf, 840K Free Swap: 32M Total, 2748K Used, 29M Free, 8% Inuse FreeBSD 4.11-RELEASE: 4MB: Dies at bootstrap loader. 8MB: Dies while mounting root filesystem. 12MB: Boots / Successfully installed the default minimal distribution set. Mem: 1900K Active, 1408K Iact, 2896K Wired, 472K Cache, 1120K Buf, 308K Free Swap: 32M Total, 2576K Used, 29M Free, 7% Inuse FreeBSD 3.5.1-RELEASE: 4MB: Dies at bootstrap loader. 8MB: Boots / Sysinstall dies while extracting files. 12MB: Boots / Successfully installed the default minimal distribution set. Mem: 712K Active, 3780K Iact, 2092K Wired, 2024K Cache, 809K Buf, 520K Free Swap: 29M Total, 29M Free FreeBSD 2.2.9-RELEASE: 4MB: Boots / Sysinstall dies while probing devices. 8MB: Boots / Successfully installed the default minimal distribution set. Mem: 3764K Active, 432K Iact, 1472K Wired, 244K Cache, 420K Buf, 184K Free Swap: 42M Total, 64K Used, 42M Free I also did a minimum disk space study using FreeBSD 6.0-RELEASE back in January: * 1st column of numbers are from the VM disk image file, outside FreeBSD. This is significant because it records the total disk space FreeBSD needed *during* install. * 2nd column is from inside FreeBSD with "du -m" after install. * All numbers reported in megabytes.
