This very same problem has bitten me when upgrading ours with IBM Ultrastar 36XP drives (DRHS 36D). Basically the machine won't boot at all (it dies right before the boot0 stage?) whenever this disk is partitioned in "dangerously dedicated" fashion. It doesn't even need to be the boot drive, just having present in the machine is enough. Solution: partition the disk with fdisk ("fdisk -BI" was the exact incantation I believe) to create a "true partition entry", and then disklabel it. One more argument in favor of non-DD disks. On one machine I've got a Seagate 2Gb also, DD-partitioned. It works fine, the problem is only with IBM drives (or maybe drives > a specific size?). The box is running BIOS 12.3, with all the latest firmware stuff. Maybe I should mention this to Intel. --Renaud To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
