AFAIK the 'extended translation' option on the Adaptec's is a hack for DOS etc. - it changes the number of heads on the reported geometry to 255, this lets you use large drives with the likes of MSDOS FDISK et'al... I don't think it would make much difference to FreeBSD (maybe to the boot process - when the BIOS is used to load the kernel)... I'm pretty sure some of our machines here run with it enabled, some with it disabled... Most are machines here use 9.1Gb drives and up, and we've not had any problems... -Kp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
