We have a handful of idle powercrypt cards, which are Hifn's IIRC, idle here, and we have boxes without the i810 entropy device on their motherboards. This would be handy. Did you just dump the entropy into the existing entropy pool of the standard random(4) driver, or does it replace the driver with 100% hardware entropy? What kind of entropy bandwidth are you able to get? cheers, Adrian -- [ adrian@ubergeeks.com ] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
