FreeBSD misdetects the amount of installed memory on a K7S5A Pro board with 1GB PC3200. Force it:

Commonly used mkisofs options
mkisofs # Command -v # Verbose -gui # Format output messages for use by GUI tools -iso-level 4 # ISO-9660:1999 -D # No deep directory relocation for ISO-9660:1999 -J # Generate Joliet records for Win32 systems -R # Generate SUSP/RR records, using the Rock Ridge protocol, for Unix systems -r # As -R, but normalizes certain values (uid/gid are 0, all entries are ugo+r-w, etc) -no-pad # Do not pad ISO to 150 sectors (useful for DVDisaster or uzip images) -p CyberLeo # Specify string for 'Preparer' volume header field -V FS-Label # Specify string for 'Volid' (label) volume header field -o <file>.iso # Name of file to hold resultant image <sourcedir> ... # One or more directories whose contents will be shoved into the image root
Rubygems will no longer fall back to installing into ~/.gem if running as non-root. Provide --user-install on the gem command line to fix.
