If you have swap section 512 Mb that it is not necessary change anything
. Simply add operative memory and all.

Subject: changing swap size


Following the advice about periodic freezes, I am going to add some RAM
to my system. However, currently my swap size is 512MB. If I increase
RAM to, say, 1GB, would I need to change the swap size to 2GB? If so, is
it a safe process (I assume this can be done using FIPS)? Would I need
to boot first in single-user mode? Any other thoughts? BTW - is there
any easy way to make sure how much RAM is currently installed other than
looking into the hardware? Top:

Mem: 146M Active, 23M Inact, 98M Wired, 15M Cache, 41M Buf, 22M Free

Which would seem to suggest I have 345 MB RAM. But from what I recall
this machine uses 320 MB RAM. Thanks!
