It seems that didier@omnix.fr.org said:

/dev/sd12g 279647 217650 39625 85% /spare
Only CVS here for /usr/src, /usr/ports and the secure code from ZA.

It is in the FAQ :-)

8.6. I have 128 MB of RAM but it seems that the system use only the
first 64 MB. What's going on ?
Due to the manner in which FreeBSD gets the memory size from the BIOS,
it can only detect 16 bits worth of Kbytes in size (65535 Kbytes =
64MB). If you have more than 64MB, FreeBSD will only see the first
64MB. To work around this problem, you need to use the kernel option
specified below. There is a way to get complete memory information
from the BIOS, but we don't have room in the bootblocks to do it.
Someday when lack of room in the bootblocks is fixed, we'll use the
extended BIOS functions to get the full memory information...but for
now we're stuck with the kernel option.
options "MAXMEM=<n>"
Where n is your memory in Kilobytes. For a 128 MB machine, you'd want
to use 131072

Uh? 256 users on the *same* account ? What did I miss ? I guess you mean
256 users at the same time, no ?
