Don't intend to buy, I expect Intel (or somebody) to GIVE me one to play with :) How's this for a scenario: We get an 8-slot passive-PCI chassis (or one of those SuperMicro's that was mentioned before) with a P-II/400 on its master, then put 2 DPT's each with 3-4 small FW-SCSI3 disks and populate the other 5 slots with the Intel intelligent 100/Pro cards. -- oooOOO O O O o * * * * * * o ___ _________ _________ ________ _________ _________ ___==_ V_=_=_DW ===--- Don Wilde [don@PartsNow.com] [http://www.PartsNow.com ] /oo0000oo-oo--oo-ooo---ooo-ooo---ooo-ooo--ooo-ooo---ooo-ooo---ooo-oo--oo  To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
