When I was building out a 6.0 box a few days ago using 4k sector drives, I first booted into rescue mode and partitioned using fdisk via: fdisk -uc -H 224 -S 56 /dev/sd{a,b,c,d} (I'm not sure, but the -H and -S might be irrelevent due to the -uc.) The first partition then defaulted to starting at sector 2048 (one MB), size of 200MB. On all disks, one other partition was created holding the remainder of the disk. All partition types were set to 0xfd. I then booted the install disk normally and eventually things got configured so that partion 1 on all drives makes up a 200MB mirrored /dev/md0 for /boot, and everthing else went into /dev/md1 as RAID6. As far as I can tell, I've not buggered things up ... Devin
