Thus far they are working OK under 3.0-CURRENT (as of 15th(ish) of April) - and I'm using "flags 0xa0ffa0ff", which I beleive is bus-mastering 32 bit "max. multisector" the drive will negotiate for... They survived a 5gb 'restore' from tape, and a 3gig dump to another SCSI drive... If I put them back in my 2.2.6 system and go for 32 bit / multi-sector - they barf... If I run them on 2.2.6 with just multi-sector - there happy... I guess this doesn't really help much :-) Both my 2.2.6 and 3.0 systems are running 440FX chipsets... I guess if were talking defaults for 3.0 I'd say 32 bit is probably OK... Kp -- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
