Did you ask if there's PAE support in Linux? There is. PAE seems to be of dubious value though. Apart from performance issues, even though you have 36-bit memory addressing, your programs still use 32-bit addressing; also, if I remember correctly, user programs in Linux are limited to 3GB each... Seems to me that it's better to go fully 64-bit rather than utilise the PAE hack. -- Regards, Juha To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
