I wanted to add to this for the archives. We have tested RaQ3s and RaQ4s with 768MB RAM one 512MB and one 256MB. They run FINE, went through a restore with 80GB drives, and never had and error. So, our recommendation is to use 768MB Gerald -- http://frontstreetnetworks.com | http://store.raqware.com Front Street Networks LLC, 229 Front Street, Ste.#C New Haven, CT 06513-3203 | phone: +1-203-785-0699 _______________________________________________ cobalt-developers mailing list [EMAIL PROTECTED] http://list.cobalt.com/mailman/listinfo/cobalt-developers
