 Subject:  RE: Freeze with 47 MB RAM?... not enough?
 Date:  Thu, 19 Aug 2004 11:04:53 +0200
One of my m0n0 boxes is a p120 with 48 MB ram. Stable as a rock.

From the m0n0 website I understand that the amount of RAM is especially
important when it comes to firmware uploads. With PC based m0n0's booting
from CD this is not an issue since firmware uploads are not supported.
